Q 8651: We have been sealing our Black Galaxy counters with a solvent-based sealer for the past 3 years. The last time we sealed it was a few weeks ago and we are having a problem with buildup and smudging. The counters were originally sealed by the installer who simply stated "any granite sealer would do". After rubbing and rubbing for days I decided to look on the internet for solutions. I found this website and some information stating that the counters should not have been sealed in the first place. Where do I go from here and how do I maintain them going forward? Reply

Q 8650: I recently had granite countertops installed and shortly after completion came home to discover a huge coffee stain ring surrounding the coffee pot. I had not noticed this before leaving the house so it had about 8 hours to be absorbed.
I was unable to link to your site for advice on stain removal. I have being reading that hydrogen peroxide can be used to remove stains from granite. I was wondering if this product would be harmful to the stone in anyway? Much Sadness,
Reply
R1: Dear Much Sadness: (This ain’t your real name, is it? :lol:) When it comes to stain removal, either you buy one of those expensive “Professional kits” (that no true professional ever uses!) at a stone retailer near you, or you can spend less money and get my comprehensive guidelines on how to remove stains by using inexpensive and far more effective means that you may already have in your household! Such impressive piece of literature will also tell you how to tell stains apart from “stains”, and what to do about the latter! Ciao and good luck, Maurizio, Expert panelist 
Q 8649: We're thinking of having granite countertops installed in our kitchen and I keep reading were you say "maintenance is an all too important yet neglected subject that should begin before you even select it" and "get my thorough and in-depth maintenance guidelines for residential stone installations". I'm writing you as stated as I'm interested learning your guidelines. Can you forward them to me? Thanks Stan, Reply
R1: Dear Stan: First off, there’s no need for me to forward the guidelines to you. Bear in mind, however, that at this stage of your “stone adventure” the most important article you want to get hold of is “How to Shop for a Granite Countertop”. In fact, the man is much more important than the stone! Ciao and good luck, Maurizio, Expert Panelist

Q 8647: We installed white Carrara marble tile on our bathroom floor about 1 year ago and the tiles around the toilet have yellowed. i have looked though your forum and found out that this will be due to water/moisture. is this common around toilets? was wondering if i may have to remove the toilet and check for seepage...also, tiny black marks have started to appear. will this be acid etch? i'm pretty sure the guy that installed didn't seal it. is this something i can do now, or is i too late? is there a product i can use to remove the black marks and then seal over the floor? many thanks, andy, Reply 
R1: Dear Andy: You have a leak from the wax seal under the toilet and the moisture soaked the marble tiles oxidizing the iron mineral that White Carrara marble is rich with. In a nutshell: your tiles are rusted through and through and there’s nothing that you can do to remove the stain. The tiles have to be replaced after you solved the structural problem that caused the damage, of course. As for the tiny black marks you’re reporting, I have no idea what they could be without actually seeing them, but I can assure you that the lack of sealer has nothing to do with them, no matter what they are. Ciao and good luck, Maurizio, Expert Panelist 
Q 8646: Rusty water from my planters has seeped onto and over the sides of my granite stairs. Will RSR remove it? Please advise. Thank you. Shelley, Reply
R1: Dear Shelly: You do NOT want to use RSR on granite! Don’t even think about it! When it comes to stain removal, either you buy one of those expensive “Professional kits” (that no true professional ever uses!) at a stone retailer near you, or you can spend less money and get my comprehensive guidelines on how to remove stains by using inexpensive and far more effective means that you may already have in your household!

Q 8645: 1. What is the exact sulotion on how to restore the gloss of granite? The story goes like this, us we install the granite in the floor, we found out that the have not an exact level between the end to end of granite. What we did was we grind using an ordinary portable grinder with sand paper from big granule to very fine, but the result was a dull one. 2. What's come first waxing or sealing the GRANITE prior to finishing? (ready to us) 3. How can we prevent staining from granite? Hope you can give me the remedies.Thanks a lot, Reply
R1: Dear Inquirer: (got a name? :-)) You’ve gotta be kidding me!! Please, pretty please, tell me that you’re not serious!!
If I have to go along with the joke, your only option is to hire a bona fide stone restoration contractor who will have to grind, hone and polish the whole floor. Stone is polished be abrasion and friction, like gemstone, not by putting a wax onto it!
It will cost you a bundle, but, on the other hand, if you knew how to install granite tile properly, you wouldn’t need to hire a professional to fix your incompetent doing. Ciao and good luck, Maurizio, Expert Panelist 
Q 8644: Can you tell me about Kirkstone. It is from Europe, though my friend got it through New York. I love the green look and the matte finish. Is this a durable alternative for the kitchen and do you know if any fabricators in the Boston area? Gina, Reply 
R1: Dear Gina: Kirkstone is quarried in England and belongs to the slate group. You do NOT want it anywhere near your kitchen!
Consider hone-finished green marble treated with a good-quality stone color enhancer (instead of a regular impregnating sealer) as an alternative. Most importantly, focus on the man, not the stone! In an industry that’s virtually unregulated, how good and reputable the fabricator who’s is going to process the stone you’ll end up choosing is far more important than the stone itself. None of the horror stories that get posted in this very site stem from the stone itself: they all stem from the fabricator. That is why I seldom make final statements about any one particular stone. There may be differences within the same stone (and I’m not talking about looks, here!) from one bundle of slabs and the next. The slabs may have also been either “doctored” (which is bad), or “resined” (which could be good, but only to a certain extent) by the factory, which would make a big difference. Even more important, what’s a good stone in the hands of some “Michelangelo”?! And again: a reputable fabricator will only carry high-grade slabs, not some “special!” Ciao and good luck, Maurizio, Expert Panelist
Q 8643: I've just read all the reasons not to have Absolute Black honed "granite". Unfortunately, we knew nothing of your site until after we had it installed in our kitchen. Our granite was sealed by the fabricators and again on site by the installers. We now know it is not needed. I would like to use stone color enhancer / sealer as you recommend to cut down on the dark marks, etc. Should we strip the current sealer off first, and if so, how? I'm troubled some by the finger smudges, etc., but also by the lighter dusty swirl marks the installers seemed to seal into the surface when they put the finish on it on site. Also, the installers said to use Windex to clean it, which seems to work somewhat. The person who drilled more holes for us later said not to use the glass cleaner because it would eventually take off the finish and etch the surface of the stone, which adds to our confusion. Thanks, Mary, Reply 
R1: Dear Mary: You MUST get rid of the impregnating sealer! And the only way to do that effectively is to have a professional stone restoration contractor re-hone your countertop with honing powder. It will be money well spent, because the honing performed by using a good-quality honing powder will give a finish that’s much better (more uniform) than the one produced by the factory. After that you will apply a good stone color enhancer like my outlandish MB-6.
Now remember, it’s never too early to think about the proper maintenance of your stone. The issue of what you’ll be doing day in and day out to your stone is far more important than the sealing itself and it’s all too often neglected. As you can tell by reading many of this site’s postings, you’re not likely to get good information about it from your dealer or installer. Don’t become another statistic!

Q 8642: I am laying 12x12 inch honed and filled red travertine Turkish tiles in my 10x12 foot entry way. Currently, there are 1/2 inch thick hardwood boards (some damaged) over a wood diagonal board subfloor. I am not sure what I have to do to prepare the floor for the tiles. I think I need to pull up the old hardwood but am at a loss after that (new subfloor, underlayment, backerboard, mortar, it all runs together for me). Any help would be appreciated. Thanks, Crystal, Reply
R1: Dear Crystal: Your query requires more attention than usual, however. “One-on-One” consultation service that’s available there for a small fee. I will be more than happy to answer up to four (4) of your questions.  Ciao and good luck, Maurizio, Expert Panelist 
Q 8641: Hello, We had Limestone 18x18" tile installed in two of the rooms in our home about 3 weeks ago.("Batig Blue" to be exact). The tiles appeared damp at first, and have slowly dried somewhat, but there are still damp areas, specifically directly around all of the grout lines. At this rate of evaporation, it looks like it could take 3 months for them to dry! The problem is, I want to seal these tiles since both these rooms will be used as art & painting studios. We have a very excellent solvent-based sealer we used on our slate floors (Fila Wet), but requires that the tile be absolutely dry and clean. Our contractor, though very good, knows very little about this kind of thing, let alone understanding the English language. Do you have any experience with this issue with Limestone tile? Advice would be much appreciated. Thanks, Chris, Reply
R1: Dear Chris: By saying limestone you’re saying absolutely noting. There are many different (and I do mean different) kinds of limestone that span from dense and (almost) acceptable rocks, to limestone that will actually melt under running hot water, and everything in between. So which limestone do you have? I really don’t like your report of this excessive drying time. Are those floors installed on a concrete slab on grade? And if so, did the installer apply a proper water-proof membrane on the sub floor? Ciao and good luck, Maurizio, Expert Panelist
Q 8640: I just built a new home in India with marble floors. The marble is cream colored. (Not sure if this is relevant, but the dealer told me it was quarried in Oman, but someone else said Italy and a third person said Turkey.) The marble floor was installed in slabs of 2 feet by 3 feet. I just moved into he house last week and noticed that there are dark (yellowish) water stains roughly parallel to the joints between the slabs. (The contractor says he filled the joints with something called "white cement" and then applied a checmical treatment to the entire floor.) Is there anything that I can do to remove the unsightly stains short of replacing the marble? (BTW, the contractor does not know English and I do not know his language, so I am not even sure what he has done with the marble.) Could this problem have been caused by rain water falling on the floor during the marble laying process? (The windows were open during that time.) Thanks for helping! Vic, Reply
R1: Dear Vic: I don’t have a clue on what your installer did to that floor, but the mention of “chemical treatment” gives me the creeps! (Could it be “crystallization”?... I can’t think of anything else.) If that’s the case I’ve got some good news and some bad news for you. The bad news is that the floor is doomed. The good news is that’s only money! If it’s something different, then there could be hope. You must find out exactly what this vague “chemical treatment” is all about, and then we’ll take it from there. Could I ask you for a personal favor? Maurizio, Expert Panelist 
Q 8639: We are looking at either Verde Tropical or Emerald Pearl "granite" for our kitchen counters. I know that black granites should never by sealed or honed. Does that hold true for these darker green "granites" as well? We have not yet ordered and I want to get it right from the get go. Thanks for your advice. Chris, Reply
R1: Dear Chris: The two stones you mentioned could be suitable with a hone finish, providing that a good quality stone color enhancer like MB-6 is applied to it instead of a regular impregnating sealer. However, allow me to tell you that you’re starting with the wrong foot!
I hope you will understand the true meaning of what I’m about to say. It appears to me that like most other inquirers at this stage you seem mostly interested in the type of “granite” and/or its physical characteristics. It’s human nature at work, I reckon!:-) How about if I tell you that a certain stone is a good choice and then you get a low-grade slab? Trust me: the human factor is far more important than the stone itself and should be the only true deciding factor! Ciao and good luck, Maurizio, Expert panelist
Q 8638: I am just starting my kitchen project and have chosen the granite Costa Esmeralda for the lighter almost marbleized color greens/ yellows and softness of shade which I’ve seen in one yard and before purchasing want to get any advice from you experts. Is this problematic? Are there any tips I should be asking the fabricator ? I know just about nothing about granite and would like to try and avoid problems… By the way, I'm looking for in stock in the Los Angeles area- approx 40 square feet ---about how much should this run in materials? thank you in advance for any tips- about installation/fabricator/ and care--Myrna, Reply
R1: Dear Myrna: Quite honestly I still have to discover what kind of a stone Costa Esmeralda is. I’ve heard mixed feedback about it, but nothing definite. However, allow me to tell you that you’re starting with the wrong foot! I hope you will understand the true meaning of what I’m about to say. It appears to me that like most other inquirers at this stage you seem mostly interested in the type of “granite” and/or its physical characteristics. It’s human nature at work, I reckon!:-) Ciao and good luck, Maurizio, Expert Panelist 
Q 8637: I know you aren't suppsed to recommend specific cleaners, but I'd like to get a glossy finish on my 2 year old verde ubatuba kitchen countertops. What ingredients should I look for in a cleaner, and, of course, which should I avoid? thekisskas, Reply
R1: Dear The Kisskas: The formulation of a cleaning product is not just putting a whole bunch of different ingredients in a pot and then mixing them together. The most important issue is how the ingredients are connected to one another.
That is why I always recommend specialty cleaning agents for natural stone, like MB-5 or MB-17. (And don’t forget MB-13!) They’ve been extensively tested as being safe on just about any natural stone on the planet! Ciao and good luck, Maurizio, Expert Panelist 
Q 8636: What is the proper care of Travertine? How do I avoid wine, coffee staining Travertine? Reply 
R1: Dear Judy: Coffee will rarely stain your travertine. If it is polished (opposed to hone-finished) it will not stain it all. Wine will not stain it, either. It will, however, etch it (make a dull spot) because of the acidity inherent to wine (acetic acid). Nothing could prevent that. The issue of what you’ll be doing day in and day out to your stone is far more important than the sealing itself and it’s all too often neglected. As you can tell by reading many of this site’s postings, you’re not likely to get good information about it from your dealer or installer. Don’t become another statistic! Ciao and good luck, Maurizio, Expert Panelist
Q 8635: Can you give me some advice on Santa Cecilia? It seems to show “pitts” throughout the surface, that were not apparent when we picked the slab. Thanks, Dianne, Reply 
R1: Dear Dianne: [quote] that were not apparent when we picked the slab.[/quote]
You picked the slab? What’s your degree of expertise at doing that? All granite and most mercantile granite have (more or less) pits all throughout their texture. Santa Cecilia, which is Garnet Gneiss (didn’t they tell you that?), has typically more pits than average. If it’s really bad it could also be a low-grading slab. Ciao and good luck, Maurizio, Expert Panelist
Q 8634: I have a cast marble counter top in my kitchen and I noticed that where a glass was set there is now a water ring mark. What can I do to remove it. Thank, Genie, Reply
R1: Dear Genie: I didn’t know that they made cast-marble kitchen countertops. To tell you the truth, I would have liked it much better to never get to know it! Cast-marble does behave like true marble (etching, which is what you have), but being a manmade material I really wouldn’t know how to repair the damage. Don’t panic, though: first off, never forget that’s only money; second, I’m positive that the knowledgeable merchants that sold that stuff to you will know everything and then some about it, and will solve your problem in no time at all! Ciao and good luck, Maurizio, Expert Panelist
Q 8633: I JUST (last friday) installed soapstone countertops in my kitchen. I love them -however.... there is a small crack right in front of my sink, and behind the faucet. The installer sanded the crack, put epoxy on it, and said it was okay. I'm concerned that I should have the piece replaced. The cracks are about 3-4 inches long each and go all the way through the piece of soapstone. Can you offer me any advice? Are cracks okay in soapstone? Ann, Reply
R1: Dear Ann: “Are cracks okay in soapstone?” Cracks are NOT okay in soapstone, shampoostone or any other stone!! The areas of your countertop where the cracking occurred should have been properly rodded. Have your “no problem” fabricator replace the cracked section and demand that they rod it where necessary.  Ciao and good luck, Maurizio, Expert Panelist
Q 8632: I'm currently looking at a stone Giallo-Vizensa because my original choose was Impala Black and the dealer could not find the Black stone. I would like to know if Giallo-Vizensa is a good kitchen countertop stone? Thank you, Reply
R1: Dear Denise: I hope you will understand the true meaning of what I’m about to say. It appears to me that like most other inquirers at this stage you seem mostly interested in the type of “granite” and/or its physical characteristics. It’s human nature at work, I reckon!:-) Ciao and good luck, Maurizio, Expert Panelist
Q 8631: I have a saltwater pool with Crab Orchard stone coping that was completed in December. We also have used the same crab orchard stone on a nearby patio. I'm having a problem with some of the stones in the coping producing sandy grit that tends to get in the pool after it rains. The amount of grit varies, but I'd say that it can be as much as approximately one-third a handful (this is what I pull out of my Polaris cleaner). Some of the stones - particularly the reds and beiges - are starting to show small effects of this erosion. I can't tell that we are having the same problem with the stone in other areas like the patio, so I'm guessing that the saltwater is aggravating the problem. I've talked to several "experts" in the area, and the consensus seems to be to let the stone go through a complete weather cycle before doing anything like sealing, etc. in order to see if the stone will stabilize by itself. We like the natural stone look and want to avoid sealing if possible, but I'm concerned about the erosion. What do you think? Will any kind of sealer help this kind of problem, or will it just make things worse? If a sealer will help, is there anytime that will allow us to keep the natural look of the stone as much as possible? J. Peter, Reply 
R1: Dear Pete: I really don’t know if your stone will ever “stabilize” itself over time, but one thing I can promise you: the only good thing that a sealer for stone – any type or make – will ever do is helping their makers, distributors and applicators to put their kids through college!

Q 8630: We had 3500 square feet of Turkish travertine installed in the interior of our newly constructed highrise beachfront condo on Marco Island Florida. After the installation, the contractor (a very large, reputable one in Naples Florida) did not cover or seal the floor (it states in our contract he was to do so). Many other trades that we hired were still working inside (electricians, drywallers, finish carpenters ect.). The travertine has a factory honed finish, but most of the stones look like they have a paste or film on them, or just look dirty. We thought this would be resolved in refinshing the floor. Our marble installer hired a natural stone restoration company who came in and rehoned the floor with 180 powder and finished it with 511 sealer and enhancer. The dirty, pasty looking patches are still present. Did they not resurface them deep enough? I have read or heard something about diamond resurfacing. Could or should that be done? We paid $80,000.00 for this floor and we are very disappointed. Please respond with your expert advise as soon as possible. Thank you very much. Sherryl, Reply 
R1: Dear Sherryl: As usual, the problem is not with the stone: it’s rather with the man! I know exactly what your problem is and I have the final solution for you. I also know that the stone refinishing company is the sole cause of your problem. Considering the kind of money they made out of you, I think it’s only fair that you give them a chance to rectify the situation.  Ciao and good luck, Maurizio, Expert Panelist 
Q 8629: I moved into my home just a week ago, and my husband decided to cook maybe 3 pounds of sausage and bacon this morning, and splattered grease all over our tumbled copper slate backsplash which we have not yet sealed. I read through most of the posts on this website, and was unable to find anything specifically addressing my issue. Being a backsplash it's on a vertical surface so it doesn't provide the same options for some of the treatments you recommend for counters or floors, additionally, the countertops are coffee brown granite, so anything i use on the backsplash must not damage/effect the granite. My husband has found that a solution of our normal handwash dishdetergent and water seems to work slowly but surely at removing the grease. But my next question is sealing. 
The backsplash is light, mixed colors. light Greens, light reds, some blues and yellows but mostly greens and reds. When wet it looks way too dark so i'm worried about trying your suggestions of mineral spirits. I don't think i want a glossy look either. the grout is buckskin beige which is a light beigy brown. We purchased a grout sealer that's supposed to evaporate off of tiles and not affect color/sheen. Can anyone please enumerate my tile sealing options for me? Including any manufacturered products that might not affect the look of my slate very much, but still seal it well? It doesn't have to not affect it at all, but i don't want to take it too far away from the look we like so much now. thank you for your help, Andi Conrad,
Reply
R1: Dear Andi: The kind of slate you mentioned is rather problematic. Many a time even an impregnating sealer that’s not supposed to darken the stone will do just that. You’re best bet is to test a spare tile with one or two different impregnating sealers. As for the removal of the stains, even if it’s a vertical surface the poulticing method is the way to go. When it comes to stain removal, either you buy one of those expensive “Professional kits” (that no true professional ever uses!) at a stone retailer near you, or you can spend less money and get my comprehensive guidelines on how to remove stains by using inexpensive and far more effective means that you may already have in your household! Such impressive piece of literature will also tell you how to tell stains apart from “stains”, and what to do about the latter! Ciao and good luck, Maurizio, Expert Panelist
Q 8628: I did the lemon juice test on a sample tile of absolute black "granite". The drop just sat there, seemingly unabsorbed, for about a minute before I wiped it away. It left a light gray spot in the exact shape of the drop. The area of the spot is still shiny, but you can see it at a certain angle. I then assumed the tile must have some sealer on it that must be etched. So, I applied a stripper/remover containing methylene chloride. Nothing changed. That is, no "sealer" or dyes came off. Can it be assumed that there is no sealer on it and that the stone etched, or do I need to flood the tile in the methylene chloride based remover? I love the site and hope you can help me decide how to best use this tile. Fattie, Reply
R1: Dear Fattie: Do this: flood the tile with lemon juice or white vinegar. Let it sit for a few minutes. Wipe it dry. It should be all of the same color as the spot you have now. Spill a few drops on lemon juice (or white vinegar) and repeat your original test.
If the spots will etch again, then the stone actually etched and means that it contains some calcite binders within. You don’t want that! If instead the new test will no produce any further etching, then it means that the tiles had been doctored and the makeup is now completely removed. What you see is (a uniform, lighter color) is what you’re buying. Ciao and good luck, Maurizio, Expert Panelist

Q 8627: Based on your condemnation of slate as an inappropriate bathroom material, we found some tile that is labeled as granite for our bathroom project. For the walls, we found polished tile with a speckled, swirly grey, black and white appearance. For the floor, we found a blacker polished stone with visible crystals. How can I ensure that they are indeed granite and not marble before we put them in the hostile environment of a shower stall? Can we slip-proof them by affixing some sort of sand to the top or by a surface treatment? Could we do this ourselves or would we need to take it to a fabricator? Reply
R1: Dear Bill: It may not be true geological granite, but when they sell a stone as granite it’s never marble. At any rate, the lemon juice test will tell you. As for the slipperiness issue, the problem is solved by cutting the tiles into smaller tiles (3” x 3” or 4” x 4”) and the set them with a grout gap of 1/8”. Ciao and good luck, Maurizio, Expert Panelist
Q 8626: Can you tell me how to clean dirt and other organic material off of marble left outside? Also, I have to make a repair of a smallish five inch piece that broke off a wing.

Q 8625: We just installed granite countertops, light gold Kashmir and the day after noticed a dark stain under oil drops left over. The installer had supposedly sealed it, don't know the type used, what do you recommend in terms of type of sealer and approach with the installer as we have not paid the last half of the project. Thanks for your comments. Reply
R1: Dear Irene: Even assuming that your installer did apply a sealer to your stone, they clearly did not do a good the job. Now remember, it’s never too early to think about the proper maintenance of your stone. The issue of what you’ll be doing day in and day out to your stone is far more important than the sealing itself and it’s all too often neglected. As you can tell by reading many of this site’s postings, you’re not likely to get good information about it from your dealer or installer.

Q 8624: I'm getting nervous about an upcoming remodel involving 3 bathrooms. Please tell me what you think about the choices I've 'tentatively' made. First, on a bathroom floor (not in the shower): a bluish-green limestone called Basilica Verde (distributed by Emser). If it's an OK choice, how do I care for it in terms of 1) to seal or not to seal; and 2) ongoing maintenance. Second, in another bathroom: a travertine slab countertop (the only name I have for it is the color: "Classic".) Again, if it's a reasonable choice, what are your suggestions re sealing and ongoing maintenance. P.S. I have verde butterfly granite in my kitchen and it looks great after 5 years. I see no need to apply sealer. Do you agree? Thank you. Maybe once I have your response I'll sleep better at night. Lately I wake up with nightmares about these decisions. Kristen, Reply

Q 8622: we will be replacing some old marble tiles with newer ones on our floor. is it ok to gloss it with polyurethane when the job is done? any special preparation before we apply polyurethane? can we patch up the old cracks iwth grout just to "fill up" the cracks before we put polyurethane?

Q 8621: Hi, I was reading you site and am wondering if travertine is ok to use in a bathroom – specifically, on the floor, around the tub and in the whole shower(walls and floor). If it is ok, what is the best sealant to be used on it and what type of cleaners can I safely use? I haven’t bought the tile yet, so would like input before buying. Thank you! Kate, Reply 
R1: Dear Kate: “on the floor, around the tub and in the whole shower (walls and floor).” Yes, it is quite a suitable material, providing that’s installed properly, especially inside the shower stall! “on the floor, around the tub and in the whole shower (walls and floor).”Travertine is not very porous (I know: you’ve heard differently from left and right!). If it’s polished you do NOT need to seal it. If it’s hone-finished, you may want to consider – just as an extra-precaution - one application of a good impregnating sealer like MB-4 “what type of cleaners can I safely use?” That is what you really have to be concerned about! The issue of what you’ll be doing day in and day out to your stone is far more important than the sealing itself and it’s all too often neglected.

Q 8618: I've read most of your comments regarding marble, but still dont know which will add more value/desirability/ to the house. I purchased 120 Sq Ft of etched Marbel, it is not polished or smooth. It has a rough beautiful marbled surface. As with all homes here, there is a crawl space under the house so its not built on a slab. Presently my home contains a maple hardwood foyer, that continues around through the breakfast area and kitchen. I want to remove the hardwood and have the marbel put only in the foyer. (How do I deal with the height differance?) I plan to use a cermaic tile that matches the marbel. The ceramic tile border will but up to the marble that continues through the breakfast area and kitchen. The home is an executive home ($450,000. Plus) located in Tacoma, WA. We are an older couple that do not entertain, no children, the front door isnt used extnsively, as we go in an out the garage most of the time. We are four years from retirement and I know we will sell the home when I retire. Is it easier to sell the house with hardwood floor or marble. Which will add more value at sale time?
I install ceramic tile an do a fair job, but have never tried marble. Any advice will be appreciated. Morris,

Q 8616: I came across your very helpful website as it appears the same way most of your requests did - in a fearful panic about what to do. I have scoured the answers given and think I have my answer but given the expense of my counter tops and my total ignorance about stone I am fearful to just "wing it with a sealer." My kitchen countertops are a beautiful Green Argento Granite. I did the lemon test and after 45 minutes there was no stain. However, a month ago when the countertops were installed a wet rag that sat on the counter for an hour by the plumber (installing an island sink) that had some mineral spirit smelling liquid mixed in left a dark mark that did evaporate quickly when I removed the rag (after panicking and heart palpitations of course!). My granite installer, architect and designer say they have never sealed granite and suggest not to seal mine. The folks I bought the granite from say seal it. I have a lemon test success and a water mixed with weird substance dark stain that evaporated after 30 minutes. Please help - seal or not seal - I am desperate because there truly are no stone experts to ask here in the Bahamas. Thank you! Kelly M, Reply
R1: Dear Kelly: Although I saw it once (it’s very limited-production quarry out of Italy) I can’t say I am familiar with Grigio Argento. 
About the sealing issue, while I’m certainly not a minister of the “sealing cult” and my record shows that I always maintained that impregnating sealers are among the most overrated, oversold and over-applied products in humankind history. That doesn’t mean, however, that are totally useless products. They do have a rather important function when they are required; therefore the theory of not sealing any “granite” is an exaggeration in the other direction. Considering your report of the (temporary) staining you experienced, I would apply a good-quality stone impregnating sealer to your stone.  Ciao and good luck, Maurizio, Expert Panelist 
Q 8615: Thanks for your helpful advice on findstone.com. We just bought "New Venetian Gold". Eight days ago I left a crystal pitcher of water on the countertop, and the condensation formed a ring. Per the fabricator's instructions I tried a hair dryer and a fan. Then they came and applied a poultice (I am not sure what) and told me to remove it after 4 hours. It did lighten the ring, but it is still visible. Could it have been something in the crystal pitcher? The fabricator says water does not leave a stain, and has been adamant that there is nothing more they will do. Any suggestions as to type of poultice to try? Thanks, Christine, Reply 
R1: Dear Christine: "The fabricator says water does not leave a stain, and has been adamant that there is nothing more they will do." Wow, some customer service! I'm really impressed, especially considering that: A) they did a lousy sealing job and, B) they don't even know that a poultice can't work in only 4 hours, not to mention that, very possibly, they don't know what to poultice the stain with!
What to do now?

Q 8614: Not a fan of the "bling" that polished black granite has to offer, but love the color. I found some slabs of "antiqued cambrian black" It appears somewhat honed/polished flecks, dempled texture. I did lemon, oil, actone, water, and butter test on my sample (let it set for over an hour) and it wiped clean without leaving any stains. Could this be the answer to all of us out here that love black granite without the high sheen? I have read your website with great interest about the honed black granite advice. What exactly is this mysterious "antiqued" technique, I have not seen much written about it. Any advice on maintaining it if we should take the plunge installation for kitchen countertops? Reply 
R1:  I didn’t have the opportunity to visit a factory recently, therefore about the antiquing process I only know what I’ve been told from reliable sources. It is basically a flaming process followed by brush-honing and the application of a … fancy name! Knowing Cambrian Black anorthosite quite well, however, I can assure you that you will never need to seal that stone! All the tests that you ran confirm that big time. Just maintain it with a good-quality stone cleaner like my amazing MB-5 and be happy for years to come! Ciao and good luck, Maurizio, Expert Panelist

Q 8612: Hi, I've been reading your column about limestone floors. I had installed unfilled, honed limestone on the first floor of my new home, kitchen included. Everything you've said is true regarding cleaning. I love the floors and like the durability with pets. I wouldn't say they're the cleanest floors, but luckily I'm passed the baby crawling stages. I've found regular mopping and vacuuming with attachment for grouting and holes works well. Periodically I clean with a machine that also sucks up the water residue. Twice a year, I mix a little bleach in water and use a stiff broom in the grout crevices in high traffic areas, mainly kitchen. Then wipe with a clean damp cloth. All of this has worked well for the last 5 years. When speaking with a stone mason, he insisted that the stone be sealed and should have been done once a year. He recommended he do this when our family was out of town due to fumes. He charged $1.00 a square foot which totaled $2900! My house sitter said he was here for 2 hours. He and 2 other men applied a sealer with a cloth over the surface. In some areas where the stone was covered by area rugs, the rugs were removed, sealer applied and within 15 minutes rugs replaced. Of course I was not here and the check was immediately cashed. I have several questions...did I even need to seal? How could such a thin layer make a difference? What is the usual charge and time? Shouldn't the areas remain uncovered for a longer time? And if they are covered by rugs, why would they even need sealing? I was totally ripped off, wasn't I? Isn't this something I could have done? If it's even necessary. For that price I thought it was some very involved process. Thanks for your input!! Cindy Raleigh, NC, Reply

Q 8611: I have a biege- like dull terrazzo floor in my home and thought of using a light coat of muriatic acid, to etch the concrete out of the floor, similar to a skin peel, then fill in the etched area with either a white Portland cement mixed with small colored marble chips, or a ready made colored venetian plaster or venetian stucco, if there is such a product, then smooth and seal. Do you think it will work or do you think I'm batso? I have no previous experience but am willing to give it a go. If you don't think I'm batso could you give me any advice on how to do it. Thanks for your expert advice Stan Feinman, Reply
R1: Dear Stan: I don’t know the exact meaning of “batso” (I couldn’t find it in the dictionary), but if it means something like crazy, or koo-koo, or nutso … then yes, you’re batso, all right and big time, too!! :-)
Don’t even think about it!! Get hold of a bona fide stone restoration contractor in your neck of the woods and have you old terrazzo floor brought back to new life by slightly grinding it, honing and polishing.
A few days after the completion of the job, apply a good-quality stone penetrating sealer like my outlandish MB-4, keep it good with incredible MB-1 and, optionally, my amazing MB-7, and … enjoy!
Now, you’d better watch out! I consider stone refinishing as the very pinnacle of all the activities related to stone from a professional point of view. Unfortunately, there are a lot of quacks on the loose out there!

Q 8610: I live Florida, we are remodeling our 100 yr. old cracker house. The front porch is made of concrete, and is old and ugly. I would like to redo the concrete be covering it with slate, which is think will look in keeping with the house. Question...Do you think slate is a good choice. I am told by my local Home Depot, that the slate has to be sealed every year. What type of sealer? I saw an ad for Stain-proof, that uses silane molecules and says it will offer a 15yr seal. Also my husband thinks that slate that is sealed or even unsealed could be slippery in the rain. What do you think? thanks Barb, Reply

Q 8609: I have been looking at different kitchen surfaces and asthetically I'm drawn to limestone because of its more subtle color and pattern. I was really concerned though, after reviewing your comments. I had a piece of Jeruselum Gold , unfinished and straight from the stoneyard, which I then subjected for 10 minutes to lemon juice, A1 sauce and salsa. I didn't notice any significant change. Am I not leaving the products on long enough? Or does this particular stone fare better with regard to staining? If you believe the stone is a poor choice would you recommend a better product which has the subtle look I'm going for? Thanks for your expertise.-s.d. Reply
R1: Dear Sara: Jerusalem Gold is a very special “animal” on its own league, within the realm of limestone! IMO it is by far the best that there is out there!

Q 8608: OK, I didn't read your site before I had honed absolute black granite counter tops installed. I am good about using hot pads and cleaning up spills. But let's face it, stuff happens. Now how do I clean it? There are lighter circles where I have left wet pots to drain. The one area where I do most of my food prep is lighter. And of course finger marks galore. Help! Ane, Reply
Dear Ane: Welcome to the club, “I-whish-I-knew-better-before-getting-a-black-honed-granite-countertop!” The following is the answer that I give to all inquirers like you: “HONED-FINISHED BLACK ABSOLUTE
There are indeed different opinions on the issue of sealing black hone granite, but there is a unanimous consensus about the fact that it presents maintenance issues. The problem with honed black granite is that it is not, well … black any more! Most black stones are but an optical illusion: they become black only when highly polished, or when wet. (See the back of your slab to see the REAL color of your stone!) As you take gloss off the stone surface (and honing does just that) you lose depth of color and the stone turns gray; but when you wet it ... here it is black again! As you spill oily liquids, or you simply touch the stone surface with your fingers (perspiration), you're going to have all sorts of dark surface stains that are a terrible eyesore. Please notice that I said: SURFACE stains, not imbedded stains. In fact, you can clean those stains off (though with lots of labor), while if they were imbedded you would have to poultice them out. If you apply an impregnator/sealer in the stone you will not solve your problem one bit: in fact the sealer will only prevent liquids from being absorbed by the stone (which in the case of black honed granite is an unlikely event to begin with), not the staining of its surface.

Any solution? Well, yes: you have to give up the gray!
If you apply a good-quality stone color enhancer to your countertop (such as our MB-6, which is also an impregnator/sealer) instead of an impregnating sealer it will turn it permanently black, while preserving the hone finish. In that way, the surface-staining problem would be minimized. Let’s just hope that your fabricator, in their “infinite wisdom,” did not apply an impregnator/sealer to your stone: this would have to be stripped (not an easy feat!), or else the color/enhancer wouldn’t stand a chance to work properly.” Any other questions? And don’t you forget that in order to upkeep your stone and the color enhancer, your best bet is to use out MB-5 and/or MB-17 for your daily care! Ciao and good luck, Maurizio, Expert Panelist
Q 8607: Our new installed travertine floor is just finished today and looks beautiful. It has chiseled edges with grout filled all over in a bone color. We did see a finished home with the same material before purchasing it a month ago.
I was skeptical at first because of its porosity, but was assured by the store owner (manufacturer from Turkey) that if properly sealed 2 to 3 times, nothing would go through. So, of course this was reinterated to our installers (recommended contractors) who just finished the floor 4 hours ago. They knew I wanted to test a sample area with a little bit of coffee - which I just did (yes, the floor was dry at this time), and to my great surprise, the coffee stained right away the grouted joint !!! I will call them tonight to correct the problem: -Should this be sealed once or twice more ? and at what time intervals ?
-Also, would more sheen to the sealant help protect better? (they have been using AquaMix Ultrasolv) Thank you, Valerie Wiese,

Q 8606: we are considering putting travertine in our kitchen and bathroom, but are concerned about scratches and how to remove them. I have a sample tile at home that I scratched with a coin to see how easy it was to make marks, then subsequently cleaned it with a mild soap and a soft scouring pad/sponge. The coin marks came off with a little elbow grease, but I wasn't sure if that is the correct way to clean the tile. Also, since I have 2 young children, I am concerned about the tile breaking if they were to drop a can of soup on it for example. Does travertine break easily once it is installed? any advice you give me would be greatly appreciated. marisa, Reply
R1: Dear Marisa: I assume that you’re talking about hone-finished travertine, opposed to its polished counterpart. If well installed it will be a quite enjoyable material. Again, if well installed a can of soup will not crack the tile; it may make a nick, but then … what’s wear and tear? The use of natural stone in a kitchen is more an issue of culture than an objective matter. If you are going to be concerned about every single little damage that could occur to it, then a calcite-based stone is not for you and you should look into granite. If instead you will accept the “lived-in” look that travertine will take after years of use, then it’s “your man”! It’s like an old pair of blue-jeans, if you know what I mean.  Ciao and good luck, Maurizio, Expert Panelist

R1: Dear Rebecca: My husband heard that granite countertops emit radiation. That’s right. That is why I always tell our inquirers to dust off the old lead suit before approaching their granite countertop! People are all dying like flies if they don’t wear it! In the mildest case scenario they will grow tails, glow in the dark, and won’t be able to have babies no mo’!! Now, please don’t ask what happens to all the workers that have been handling granite professionally for years, from the quarry to your kitchen; that would be too graphic to describe, especially after dinner!! Just a little hint: the Ancient Romans were the first known people to quarry granite some 2500 years ago. And look at what happened to them: they are all dead – bar none!! :-)
I can’t find any scientific evidence for this on the web. Well, that’s the problem: there ain’t any, but if ask any salesperson of Corian and the likes, they will give you all the “scientific” information you need and then some! Where can I find documentation that proves granite countertops are safe? Concern yourself about a good fabricator and you will do just fine! Ciao and good luck, Maurizio,

Q 8603: We are interested in honed azul lagos limestone for kitchen countertop. I realize that limestone is not the ideal material but this is the only stone my husband and I both love. Is there a better limestone or a sealer/wax/impregnator that would make the limestone more durable. We don't mind the etching, but would want to minimize the stains. Elizabeth, Reply
R1: Dear Elisabeth: You’re in luck! Azul Lagos is indeed a good limestone, although with all the limitations inherent to limestone that you seem to already be aware of.

Q 8602: Hi, This is my first time on the site and it's really helpful. Although I have to say after reading everyone else's questions/problems I'm now more nervous than ever about our flooring. Here's my question. My husband and I have fallen in love with the look of Marble. It is the only tile that I've seen that I see and think "Wow, that's what I want in our house!" We would like to use it throughout the foyer, and living room. (480 sq ft.) - Also doing a focal wall with "Cignus" and an inset of "Jade Green Onyx".

Here are my questions....

1.Nobody gives me a clear answer on how often residential Marble (placed in regular traffic area) needs to be sealed. (ie Every 6 mos, Every year, or Every three years.) Is there an approximate time frame that I can use to figure into our decision?

2. A lot of the sales rep's get this pained look on their face when I tell them that I'm looking at Marble for our floors. They always try to steer me to the porcelain, telling me that Marble will scratch too easily and crack. Why do they keep telling me this? I know Marble is used in hotels and other high traffic areas, so why is installation in a residential house such a bad choice?

It is my husband and myself & our two dogs (cocker spaniel & maltese). When we have kids, I'm just going to make sure that they don't run, etc... where the Marble is. (I know, don't make a face, people look at me weird over that statement too....) The thing is, I don't want porcelain, I don't like how it looks. Every store I go into has all of these tiles that look just like all the tiles in the other stores. Unless Marble is REALLY going to be a problem, I want to stick with natural stone.

3.We live in Houston, TX (very humid during summer). My question is about the installation. The contractor that I'm using recommended putting "antifracture membrane" between the cement floor and the tile. He said that it would keep the tile from cracking if the foundation "settled". Is this a good recommendation? Also, in other Q&A's I noticed people have had problems with grout
and other things drying properly after installation. We were preparing for installation in August. Should we hold off until November when the whether is not humid and alot cooler?

4.I noticed in another Q&A that you had that a listing of Marble grades was given. I've found a Marble that I would like to use on the floors. It is called "Bologna Gris" Kind of mottled grey's and creams with a hint of pink/brown tones and little gold striations every so often. I've been looking on the Internet to find the manufacturer so that I can get the hardness scale but can't find it anywhere. Has anyone heard of it? I'm in Houston, TX and found it at Floor Decor if that helps. Thank you so much for any input. This is our first house and I'm really nervous about making a huge mistake because I didn't get enough information before installation. Lori, Houston,TX, Reply

Q 8601: I was very relieved when I found your website...Thank you! I recently purchase approximately 2200 sq. feet of travertine for my new home. The dealer knew that I wanted a glossy floor. When the travertine was being installed I mention the dealer that it was dull. He assured me that after installation the floor would be sealed and it would shine. Well, when the installation was complete the tiles has highs and lows dried bubbles and still looks dirty. The dealer returned and applied a second coat of sealer. It still looks the same. He has informed me that he returned and did the second coat of sealer as a favor because travertine tiles do vary in height and because I wanted so much fill that the chemistry of the fill and the travertine are different therefore absorb the sealer differently and nothing could be done. I am livid. I spent a HUGE amount of money on these floors and I hate them, they look dirty all the time. Is there anything I can do in order to get an even gloss on my floors?

Q 8600: I have recently installed 700 sqft of 24X24 turkish travertine, and now after a couple weeks, more than 1/3 of the floor is hollow, the tile is litterally comming completely off the floor, without any adhesion of the thinset to the floor. Anyone know how I can overcome this? Is there a moisture issue? Is there a chemical reaction between the slab and the thinset? The home is located in Wagonwheel (Trabuco Canyon), CA. Thanks, Wayne, Reply

I work for a fabricator in Texas and have enjoyed this forum for several months now. I've even responded to a few simple questions where I was confident I could assist the questioner accurately. In fact, I've been so impressed with the volume of accurate information (it's amazing how much garbage about natural stone is really out there) that I've recommended your site to several potential customers. I like that they can see for themselves that what I say when we discuss their project is true, and I like that you really don't hold much back. Most of them that actually checked out the site have had very positive things to say. They usually go on to say how much "crap" information they received at some of our competitors. In many cases the information they gained at your site was the difference between choosing us instead of the "other guy" as their fabricator.

I've only been in the stone industry for about three years and like every venture I undertake, I like to educate myself as much as possible about what I do. Much of what I've learned, I found right here at your website. Just wanted to say "thanks" and to keep up the good work. Some of us are really listening. --Alisha
