GRANITE
COUNTERTOPS?
Question
1: What do I need to
consider when buying marble or granite?
Being natural stones, marble and granite have
been blessed with remarkable characteristics that have
captivated humans throughout the ages. Inherent in such
natural products is a certain lack of predictability that
architects and designers celebrate. Consumers who are less
acquainted with the material expect the stone ordered to be
identical to a picture or sample they were shown. Although
sample stones are intended to be representative of the
quarry's product,
the material quarried at
one time may differ slightly in color and veining from the
sample. Moreover, even a single marble or granite slab will
possess a certain amount of color variation from one end to
the other. Interior designers and architects have come to view
this tendency of natural stone as an advantage. Slight
irregularities can be pleasing, introducing an element of the
natural into human designed spaces, whether residential or
commercial.
Question2:
What's the difference between
marble and granite?
Although both are stones and quarried from the
earth,
granite and
marble
(and marble's relatives limestone, onyx and travertine) are
very different from each other. Granite is formed deep in the
earth's mantle at extremely high temperatures. It is a very
hard, resistant stone made of crystallized minerals. The
marble family limestone, travertine, marble and onyx start out
as sediment animal skeletons and shells, plant matter, silt at
the bottom of bodies of water. After millions of years this
solidifies (lithifies) into stone. Because its main component
is calcium, it can be affected by acids such as vinegar and
citrus.
Question3: Should
I use marble or granite for my kitchen countertop?
Although typical application of marble is for
the bathroom vanity tops, Jacuzzi tops and fireplaces, it is
possible to use it in the kitchen. However, due to the fact
that it is easy to scratch and is affected by acidic
substances, such as vinegars, ketchups etc, we don't usually
recommend it. Moreover the high gloss of the marble countertop
can be partially lost as many chemicals etch its surface.
Granite in turn is considered the second hardest stone, its
polish is not subject to etching by household acids, or
scratching by knives and pots and pans under normal use. It is
also not affected by typical kitchen heat such as hot pans.
Question4: Is it
necessary to seal stone?
Since mineral surfaces are quite porous they
absorb liquids, which may result in discoloring and staining.
Although there are many commercial grade products available on
the market which may bring the stone to its original luster,
taking simple precautions and regular maintenance can save a
lot of trouble and cost. All marble and granite tops are
sealed
in our shop before they are installed. The
impregnating substance penetrates the stone clogging most of
its pores making it quite impervious to alcohol, juices, soft
drinks, cosmetics, cleaners, coffee, food and even oil. With
course of time and every day use the sealer wears out. The
clear indication of this happening would be the fact that
liquids are easily absorbed into the stone, opposed to
bubbling up on the surface.
Question5: Do I
have to buy the whole sheet/slab?
Slabs are always sold intact. Buying random
slabs is similar to buying fabric. Like a seamstress or
tailor, your fabricator buys the raw material and sells you a
completed installation. In the price is included the cost of
transporting the material, making field measurements and
templates, cutting, polishing, bringing the pieces to your job
site and fitting them into place. How much material he needs
is determined by the layout and the amount of waste. The
fabricator will lay out your job in a way that will minimize
the amount of waste material while maximizing the natural
beauty of veining and pattern.
Question6:
What is the
best way to clean marble and other stones?
The old rule of thumb is never to use anything
you wouldn't use on your hands. Never use powdered cleansers
or abrasive pads to clean your stone. Even "soft scrub" type
cleaners contain pumice, which is powdered volcanic stone, and
might damage your marble vanity tops or floors. You should
always use sealers and cleaning products designed for natural
stone. Clean your stone with lukewarm water and dry with a
cotton rag.
Question7:
How do I deal
with sink and stove cutouts?
With
CNC technology
we have the ability
to cut any sink or surface unit cutout with computer aided
design files. Undermount sinks (sinks that are mounted under
the countertop so as not to show any rim) are fully cut out,
then the inside rim of the cutout is polished. The countertop
is also fitted on the bottom surface of the top with special
cutouts that accept a steel anchor that will allow us to
mechanically attach your sink to the top. Self rimming cutouts
are only scored 6" into each corner leaving some of the
material to be cut in the field to facilitate safe shipping.
Question8:
Can I cut on my
granite countertop?
Only if you want to ruin your good knives.
Granite is harder than your knife blades and will dull them
very quickly, if you use the countertop as a cutting surface.
Always cut and chop on a wooden or plastic cutting board.
Question9:
Can
my granite top be damaged?
Like any solid surface, high impact blows can
harm granite. Because of its crystalline structure, it can
chip if subjected to hard blows with sharp hard objects.
Unsealed, granite can absorb stains such as oil, which can
ultimately cause dark spots or discoloration. Heat from pots
and pans or burning liquids will not affect granite under
normal circumstances. If you have a stain in your top contact
your stone supplier, they can help you
remove the stain
by supplying you with a poultice that you can apply to the top
to remove the stain.
Question10:
My little sample
of granite has pits on the surface. Will I have these on my
kitchen counters?
Yes, granite being crystalline in structure
always has tiny pits and spaces between the various mineral
crystals. Some granites pit more than others when being
polished, we suggest that you take a closer look at the slab
you choose for your job. Chances are, if you look at it across
the light you will notice the natural pitting of that stone.
Remember, this is natural and it should not be considered an
imperfection of the stone. Granite sometimes has natural
fissures as well, which may look like cracks, but are not
structural defects and are a naturally occurring result of the
immense heat and pressure which formed the granite eons ago.
These characteristics are part of the natural beauty of stone
and will not impair the function or durability of the
material. A product of nature cannot be expected to look
manmade.
Question11:
How do I clean my
granite tops?
POLISHED GRANITE is a very durable stone, much
harder than marble. Granite has been used in the past in the
commercial industry.
Some of the
obvious applications have been
panels on the outside of buildings, walls, and floors of "high
traffic" areas. Granite will withstand almost any element it
comes up against including heat and cold. Granite itself is
approximately 9598% stain resistant although, we use a
silicone impregnator sealer
on all our natural stone products. This will insure lasting
life and beauty. Polished Granite should receive the same
cleaning care as polished marble, use lukewarm water and dry
with a cotton rag. When needed, spray glass cleaner (i.e.
Windex) and paper towel dry.
Do not let window cleaner sit on granite
surface, clean right away.
Question12:
Will my granite
look like the sample I saw in your showroom?
The samples you see on our website computer
have been scanned and saved as digital images. Variations are
expected and are the source of stones natural beauty. That is
why we encourage any of our customers to inspect the actual
slabs we have for your project before production begins.
Nothing compares to actually being able to select the slab to
be used in your job. This is the best and only way to ensure
that color, veining and characteristics on any of our
materials are to your satisfaction.
Question13:
Does granite
stain?
In general, no. All stone, however, is porous
to some extent, but Granite has very little porosity. Most
colors will never show any moisture. A few colors may show
some moisture if exposed for a period of time. For example, a
puddle of water left on the counter for 30 minutes for some
colors (specially lighter), may show a dark spot when the
water is wiped away. This spot will then dry up and no
evidence will show.
Question14:
Can I set hot pot
on my granite countertop?
Granite is formed by extreme heat and pressure
combined beneath the earths crust. It cannot be affected by
heat from a cook top or frying pan. A lit flame placed under
the granite will have no melting effect and will not leave any
burned or scarred marks.
Question15:
Can granite chip?
In only cases of sever abuse with a hammer or
impact tool. A chip can be filled with a granite dust and
epoxy mixture.
Question16:
Do
granite seams show?
Because granite is a natural material and is
mined from the quarry in blocks usually no more than 9' to10'
in length, you will end up with seams. Also, because granite
is sold in rectangular pieces, you may want to use seams to
reduce your costs, such as in an 'L' shaped corner. The
visibility of seams will depend on the granularity, color and
pattern. A small, uniform grain will not be as apparent as a
larger varied grain. A dark color will be less apparent than a
light color. A dramatic pattern with swaths of color
definitely will show more seams than a uniform pattern. Most
customers have found that the beauty of natural granite
outweighs the concern of seams.
Question17:
How are seams
made?
Seams are created by joining two pieces of
granite together with a knife grade epoxy that is color
matched to the background tone of the granite countertops.
Suction cups and seamers are then used to tightly join the
pieces together. Any excess bonding material is then cleaned
off the surface with razors to leave a smooth and sleek bead
of epoxy between both pieces. Occasionally, in areas where
expansion and contraction are predominant, the use of silicone
replaces the epoxy.
Question18:
Does granite stain
or burn?
No. You can't burn it with ordinary use.
Granite does not stain. The only caveat is that a few colors
may absorb some moisture with prolonged contact. Usually, no
evidence remains when the liquid is removed and the granite
dries, but could be a problem with dark pigmented liquids.
Question19:
Can granite crack?
Not with ordinary use. Granite is most
susceptible to cracks during shipping and installation. Normal
use will not overstress this durable material.
Question20:
Can
granite cantilever?
You can cantilever granite up to 12" with
sufficient support on the fixed end and with a large enough
piece. Never cantilever unsupported granite where it might
receive excessive stress like someone sitting on a counter or
stepping on a counter to change a light bulb. You must have
support underneath for these situations.
