Q1:
I am planning to re-do my kitchen. What should I choose for
the counter. I have a choice between Marble and Granite.
R1.
Ideally the kitchen counter in India should be of a non-porous
stone as Indian cooking involves a lot of oil. Porous stones
not only absorb oil and dust but also food particle and food
juices which later on provide breeding ground for bacteria.
It also retains odor.
I would recommend a granite preferably of a uniform shade like
black or Red as they would clearly show spills and food particles.
Mixed colors in granite appear dirty.Granite
is hard and will wear well and will be less susceptible to scratches.
However if you insist on using Marble, the next best choice
is Green marble. If you like a white top then use a fine grained
marble and get it treated with a good epoxy sealer (food grade)
before laying.
Q2:
Is granite suitable for flooring?
R1:
Granite is hard wear resistant stone. This property makes
it the ideal flooring material BUT the dust and sand leaves
scratches and re- polishing laid granite is next to impossible.
Scratched granite floor looks bad. Marble being a soft stone
can easily be re-honed and polished. If the area under consideration
is low trafic with minimum dust polished granite can be used.
But be careful, if wet it can become dangerously slippery.
Un-
polished granite (honed) or even flamed granite can be used.
Other alternates amongst stone are Kota Stone, Bansi Paharpur
(a variety of sandstone).
Q3:
What do I use in a bathroom.
R1:
A classical question with numerous alternatives. We will just
concentrate on stones. I have seen practically all kinds of
stone being used, right from Polished Granite to hand chiseled
sand stone.
Ideally
the bathroom surface should be fairly rough( recommended friction
factor is 0.7 (anti-skid)) and non-porous. You can use un-polished
granite, honned marble with epoxy filling and sandstone with
epoxy and sealer coat. The details about the chemicals to
be used can be provided.
Q4:
I have a farm house where I have put up a lot of sculptures
in stone in the open. How do I protect them?
R1:
You can and should take of your sculptures. Some people want
them to age. This can be best attained by leaving them untreated
or by using specialty staining chemicals to give them an antique
look.
Alternatively
if you want them to retain their new look get them treated
with suitable sealant and coatings. This will vary from stone
to stone and we need more details to provide specific treatment.
Q5:
I have marble floor in my house. The floor is stained . I
have tried repolishing the floor but the stains do not go.
R1:
Stain removal from stone is an art. The
first step is to identify the stain. Is it oil, ink, paint,
dirt, wine, coffee, rust etc. Etc.
Once
the stain is identified special stain removal poultices are
available to remove them. The older the stains the more difficult
it is to remove them. It is best to get the stone sealed by
an impregnating sealer immediately after laying it to prevent
it from getting stained.
Q6:
I have fixed a yellow Italian marble. It was looking good
initially but within a year it has started developing holes
and pits.
R1:
You have used Travertine. It is a beautiful
stone but it inherently has pits and holes which are normally
filled using a mastic. Maybe in your case they just used pigmented
mortar which is now coming out. Get it patched with a matching
mastic and re-polished. It should last you a life time.
Q7:
I like yellow sandstone. The one which comes from jodhpur,
Rajasthan. Can I use it for cladding.
R1:
Yes you can use it for cladding but you should pre-seal the
stone as it is very porous otherwise with time you will have
colored patches.
Q8:
Which marble is the best?
R1:
Which food is the tastiest? It depends
on your choice and utility. It is very difficult to answer
this in absolute terms.
Q9:
We have an old marble fountain in our yard. We have been cleaning
the salt scales using toilet acid for a number of years. The
stone seems to be getting yellow and cracking. What should
I do?
R1:
You have been using the wrong method
for cleaning. Acid (in your case hydrochloric acid) has been
eating away layers of stone causing pores and pitting. The
yellow stain is because of chlorine. Stop using immediately.
Fountains like yours are priceless and should be preserved.
Clean up the entire stone by using an alkaline penetrator.
This will remove all traces of acid from the stone. Get the
stone polished and sealed using an ideal underwater sealer.
Q10:
We have used high quality green marble in our restaurant floor.
We have started noticing a white powder coming out of the
joints and the stone near the joints is loosing polish and
becoming rough. The floor looks bad.
R1:
It is efflorescence. You must be washing
the floor very frequently. The water is going in through the
joints (grouts) and dissolving the chlorides in the mortar.
Normally the sand in the mortar contains chlorides. This causes
the formation of a weak acid which starts attacking the joints
as these are the weakest spots and here the stone pores are
exposed . This is like a chain reaction . It is best arrested
by reopening the joints and filling with a non toxic water
based epoxy. If you want immediate results use High molecular
weight polymer oils (HMWPO). Just apply this oil on the stone
joints once a month and that sould arrest the problem.
Q11:
I am planning to build a house in Bangalore. Where can I buy
good quality stone at reasonable prices.
R1:
Right here on Findstone.com. Post your
inquiry and I am sure a couple of Bangalore stone dealers
will approach you . You can choose and negotiate.
Q12:
I have marble mines in Rajasthan. I am looking for a financial
partner. Can you help me?
R1:
You will have to give more details on
the quality, type of deposit and the kind of financial arrangement
you are looking for. Post the details on the site and you
may receive responses.
Q13:
How do I find buyers for my stone. I would prefer export inquires.
R1:
The answer is the same as for Q 15.
Q14.
I have seen a number of interesting stones on your site. Can
I get samples?
R1:
I am sorry. We can not help you directly
but you can contact individual suppliers / mine owners/traders
and they may send you samples. They may also charge you for
it.
