What are the Different Tile Types? Natural Stone,
Ceramic & Porcelain Product Descriptions
Marble
building products are processed from blocks that are
quarried all over the world. This metamorphic rock
is comprised primarily of calcium carbonate and other
minerals that create a wide variety of colors. Applications
include floor tiles, wall tiles, vanities & other
surfaces, fireplaces, columns, balustrades, water
tables, steps, thresholds & windowsills.
Polished Marble:
High gloss finish - vivid colors.
Excellent for wall and light traffic floor use.
Must use grout in any installation that may be exposed
to moisture or installation will eventually fail.
Must use unsanded or epoxy grout to prevent scratching
finish.
Sealers do not penetrate well and offer little protection
against etching and will not protect against abrasion.
Very expensive to repolish or remove stains.
Tumbled Marble:
Natural looking aged finish - soft muted colors.
Best choice for floors, bath and countertop use.
Displays best surrounded with honed or tumbled field
tile.
Must use grout in any installation that may be exposed
to moisture or installation will eventually fail.
May use sanded grout for additional strength - excellent
for outdoor applications.
Accepts enhancers and sealers readily - excellent
protection against etching - scratches are less obvious.
Resistant to staining and easy to reseal.

Granite is the most durable architectural building
stone. This igneous rock is comprised mainly of quartz,
graphite, mica and other minerals. The increasing
popularity of this stone is a testament to its beauty,
versatility and consistency. Used in a wide array
of commercial and residential applications, granite
is ideal for tile floors, walls and countertops, as
well as exterior applications such as pavers and wall
cladding. Granite is quarried worldwide, with the
most exotic colors coming from Brazil, India, Finland,
North America, China and Southern Africa. New quarries
are discovered each year further enhancing color choices
and keeping prices in check.

• • • Limestone is a sandy sedimentary
rock formed closer to the earth's surface and often
captures fossilized plant and animal life. Similar
to marble and granite, limestone is processed for
a wide range of interior and exterior building applications,
including floor tiles, wall tiles, vanities &
other surfaces, fireplaces, columns, balustrades,
water tables, steps, thresholds & windowsills.
Limestone can be polished to a high gloss finish,
but is more commonly known for its honed (matte),
tumbled (antique or acid washed) and natural (split
face or rough) finishes, typically in more neutral
tones.

• • • Travertine, mostly known
for its porosity, is comprised primarily of calcium
carbonate. Slabs and tiles are cut from blocks with
the veining (regular cut) or across the veining (cross-cut).
Processors of this material will market the stone
as is, with the holes for a more rustic & antique
look, or fill the holes with a tinted epoxy and hone
or polish the surface to achieve a solid surface effect.
The stone is used in a wide range of interior and
exterior building applications, including floor tiles,
wall tiles, vanities & other surfaces, fireplaces,
columns, balustrades, water tables, steps, thresholds
& windowsills.

• • • Slate is a fine-grained metamorphic
rock that splits into thin, smooth-surfaced layers.
The most common building applications for this material
are floor, wall and roof tiles as well as fireplace
surrounds. Tiles can be split and cut-to-size with
only the natural cleft surface, or manufacturers will
add value by calibrating the material to ensure a
consistent thickness throughout the piece.
• • • • • • •
• • • Ceramic & Porcelain tiles
are hard, brittle, heat-resistant products that are
manufactured by firing clay and other materials. Porcelain
tile is a type of ceramic tile fired from pure white
clay to generate a translucent effect. The patterns
of these products attempt to emulate the look of natural
stone products; the prices are typically less expensive;
and the color range is very consistent due to the
man-made nature of the product. As a result, ceramic
& porcelain tiles are an excellent alternative
for the value-oriented buyer. Primary applications
include floor and wall tiles, along with trim and
transition (corner, wall to floor, etc.) pieces.
Tile Terminology
Bullnose Tiles:
Trim tiles featuring one rounded edge used to finish
wall installations.
Decorated Tiles: Ceramic tiles that
have been embellished by means of hand-painting, silk-screening,
decals or other techniques.
Frostproof Tiles: Tiles specifically
designed by the manufacturer to withstand freeze/thaw
conditions with minimal effect, hence suitable for
exterior applications exposed to high humidity and
low temperatures.
Frost Resistance: Ability of certain
tiles to withstand freeze/thaw conditions with minimal
effect.
Grout: Installation material used
to fill the joints between tiles
Matte Glaze: Glaze that produces
a non-shiny finish.
Moncottura Tiles: Tiles produced
by the single-firing method. Also called Single-fired
tiles. Glazed tiles produced by the single-firing
method in which the raw tile body and gaze undergo
a single pass through the kiln at high temperatures.
Mortar: The setting material used
to bond tiles to a given surface. Different types
of mortar are suitable for different backing and conditions.
Mounted Tiles: Tiles assembled into
units or sheets by the manufacturer for easier installation.
Porcelain Tiles: Dust-pressed ceramic
tiles with water absorption levels of less than 0.5%
and high mechanical and chemical characteristics.
The surface of these tiles may be glazed or unglazed,
polished or unpolished.
Ceramic Tile FAQs
Tile Ratings Among the manufacturers
of ceramic tile there are certain standards that are
universal. ISO Standards have been established by
the International Standards Organization to unify
product standards and testing methods for ceramic
tiles worldwide. One of the most important of these
standards is the PEI rating. The P.E.I. (Porcelain
Enamel Institute) rating is a measurement of how well
a ceramic tile will wear. Generally, ceramic tile
manufacturers classify their products in 5 categories.
They are as follows:
PEI I Usually refers
to tiles applicable for wall installations only
PEI II Suitable for floor applications where there
is very light traffic
PEI III Suitable for most residential applications
other than kitchens.
PEI IV Suitable for all residential applications and
some light commercial applications
PEI V Suitable for all applications except malls,
airports and transportation terminals
In addition, there is a classification, U, which is
given to products specifically designed for industrial
applications.
What
is the difference between glazed and unglazed tile?
Glazed tile is coated with a surface finish (glaze)
fused to the body by firing at very high temperatures.
Because of the ease of adding color, pattern and texture
to the glaze, style, color and design are virtually
unlimited. The color of unglazed tile results from
the natural clay of the tile body or pigment added
to the clay. The colors are more limited but because
that color extends throughout the tile, wear is not
visible. Unglazed tile is, therefore, an excellent
choice for the most heavily trafficked areas.
Will
ceramic tile break or chip?
Ceramic tile is more susceptible to breaking before
installation than after. After proper installation,
it is very difficult to break or chip tile unless
it is hit with a heavy object such as a hammer having
a small impact area. Structural breaks can occur if
there is movement in the substrate. If damaged, individual
tiles can be replaced.
Is
ceramic tile cold?
Tile is actually the same temperature as the surrounding
air. It holds warmth in a sunny room or a cooler temperature
in an air conditioned or cold room. Body temperature
is usually warmer than the air, and this causes tile
to feel cool.
Is
ceramic tile slippery?
Slip-resistance will vary with the type of tile. Ceramic
floor tile will have about the same slip-resistance
as other hard surface floors such as vinyl or wood.
Naturally, if there is liquid spilled on any hard
surface floor, the slip-resistance will greatly diminish.
Abrasive surfaces are available on many tiles. Keep
in mind that the more abrasive a tile surface is,
the more difficult maintenance will be. Consider using
a mat at entrances and wet areas.
How
durable is ceramic tile?
Ceramic tile, properly installed, should last the
lifetime of your home with minimum care. Tile will
not show wear when used on walls; unglazed floor tile
also will not show wear. Glazed floor tile is dependent
on the durability of the glaze and body and the amount
of traffic to which it is subjected. Most manufacturers
do classify the durability of their tile.
Can
ceramic tile be used outdoors?
There are numerous ceramic tiles that are frost-resistant
and are excellent for patios, porches, pool decks,
etc. Many unglazed tiles are suitable for exterior
use. Their slip-resistance will be dependent on the
surface texture, and slip-resistance is important!
Glazed, frost-resistant tiles are recommended for
vertical exterior surfaces only. The ceramic tile
manufacturer will indicate if a participate type of
tile is frost-resistant. A frost-resistant installation
method is essential.
Does
ceramic tile have shade variation?
As is true with other quality decorating products
such as textiles, carpet, wall coverings, and wood,
ceramic tile does have shade variations. Hand-crafted
tiles generally have the greatest variation, and this
quality contributes to their unique beauty. Samples
are meant to represent the tile as adequately as possible
but may vary to some degree. Be sure to inspect your
tile before it is installed to determine if it meets
your approval.
What
should I know about grout?
Grout, the colored mortar between tiles, has been
drastically improved in recent years. It is available
in numerous colors to coordinate with your tile choice.
The actual finished grout color in an installation
is affected by moisture, temperature and installation
techniques. Because of these variables, the installed
shade may differ from a showroom sample. Choose grout
color to blend rather than match. Today, there are
grout formulas that contribute to stain-resistance
and mildew-resistance. Good maintenance procedures
that remove surface soil always improve the appearance
of any ceramic tile installation. Improved sealers
can assist in keeping the grout at its best.
Does
ceramic tile require a special floor construction?
Standard floor construction of 2" x 10"
floor joists spaced 16" on center with 5/8"
plywood subfloor and 3/8" plywood underlayment
is suitable. However, more than 20 years' experience
shows that a rigid, cementitious backer board is superior
to plywood as an underlayment. A clean, structurally
sound concrete slab is suitable and does not require
additional underlayment.
Should
ceramic tile be waxed?
Sealer is unnecessary and should never be used on
glazed tile. Sealer is often used on unglazed natural
clay tile, pavers or unglazed porcelain tile. Some
manufacturers of these products recommend a particular
sealer. However, in most cases, a good penetrating
sealer is advisable. It is usually invisible or provides
a soft luster. Heavy sealers such as urethane are
not recommended because of potential scaling or uneven
wear.
Should
sealer be used on ceramic tile?
The initial installed cost of ceramic tile may be
higher than other finish materials. Today's improved
technology, marketing and competitive pricing have
decreased the margin of difference. When considering
the true cost comparison, you must look at the life
span of ceramic tile. Due to the fact that you probably
will never have to replace your tile and the low cost
and easy maintenance, ceramic tile is the least expensive
of all finishes. Statistics show that an investment
in ceramic tile will increase the value of your home.

Ceramic Tile Care
Type of Tile/Usage
Routine Cleaning
Heavy Duty Cleaning
Glazed Walls/Countertops
Wipe with damp cloth or sponge using all-purpose
cleaner. Use window cleaner for glossy surfaces.
Wipe dry with cloth.
Clean with scouring powder, commercial tile
cleaner, or all-purpose cleaner using non-metallic
scouring pad or very fine grade stainless steel
pad. Rinse and wipe dry.
Glazed Tile Floors
Vacuum regularly to remove gritty particles.
Damp mop using solution of water and "soapless
detergent.
Use a commercial tile cleaner or a strong solution
of water and "soapless" detergent. If
stained, use scouring powder paste. Let stand
for five minutes, brush and scrub. Rinse and dry.
For large areas and for areas that are difficult
to clean, a power scrubber is recommended.
Glazed Tile Showers
Use all-purpose or bathroom cleaner. Allow to
stand for five minutes rinse and dry. May also
use a mixture of equal parts water and white vinegar
or a commercial tile cleaner.
Use chlorine bleach or hydrogen peroxide*. For
stubborn stains, use scouring powder containing
a bleaching agent. Let stand four to six minutes,
then scrub and rinse thoroughly. To remove mildew,
use a commercial tile cleaner, chlorine bleach
or ammonia. DO NOT MIX.
Unglazed Tile Walls
Sponge with a diluted solution of water and
"soapless" detergent.
Use scouring powder paste. Let stand for five
minutes, then scour with brush. Rinse and wipe
dry.
Unglazed Tile Floors
Vacuum regularly to remove gritty particles.
Damp mop or sponge with water and/or a diluted
solution of water and "soapless" detergent.
Use scouring powder paste. Let stand for five
minutes, then scour with brush. Rinse and wipe
dry. A small brush is suitable for small floors;
consider a scrubbing machine for larger areas.
Natural Porcelain/Semi-Polished Porcelain**
Vacuum regularly to remove gritty particles.
Damp mop using a solution of water and "soapless
detergent", rinse and then wipe dry.
Use scouring powder paste. Let stand for five
minutes, then scour with brush. Rinse and wipe
dry. A small brush is suitable for small floors;
consider a scrubbing machine for larger areas.
Commercial Applications
For smaller commercial areas, vacuum
regularly to remove gritty particles. Using a
"soapless detergent", scrub with an
inexpensive nylon brush (such as a "Doodle
Bug"). Follow by using a dry/wet vac to remove
water and soap residue. Note: After initial cleaning,
replace nylon brush. Replace thereafter as it
becomes worn. A clean scrubber makes for a clean
floor. For large commercial settings, consider
the use of a commercial floor scrubbing machine.
* With colored grout,
test a small inconspicuous area first or follow grout
manufacturer's instructions.
**A note on Semi-Polished
Porcelain: Porcelain tile is virtually impervious
to stains and wear. However, the polishing process
opens microscopic pores in the surface of the tile.
Therefore, it is recommended that a penetrating sealer
be used 2 hours prior to grouting. Penetrating Sealers
need only be applied once, following the manufacturer's
instructions.
Remember, prompt
clean-up of spills and regular cleaning will keep
your ceramic tile surfaces looking their best.
DO's
and DON'Ts of Ceramic Tile Care
Do not combine ammonia and household bleaches.
Do not use harsh cleaning
agents (such as steel wool pads) which can scratch
or damage the surface of your tile.
Do test scouring pads
in a small area first.
Do use a silicone sealer
on grout joints if continuous staining is a problem.
Do read and follow
label directions for all cleaners.
Do visit El Dorado
Tile Marble and Granite for advice on special cleaning
problems or if you have any questions.
Care
and Maintenance of Tile Grout
Grout may present a special cleaning problem because
it is susceptible to many staining agents. Apply a
silicone sealer to grout joints several times a year
for maximum protection.
In addition to keeping
the grout clean, be sure to keep grout joints in good
repair. Scrape out loose, cracked or powdery joints
and refill with a good grout.
One common grouting
trouble spot is the joint between the tub and and
the wall in your bathroom. As the house or tub settles,
the grout may crack and crumble. It's relatively simple
to remedy. Remove the old grout with a sharp pointed
tool, watching out that you don't scratch tile or
tub. Then dry the joint thoroughly and fill with a
flexible caulking compound, such as silicone rubber
caulking

*Caution: Vinegar may damage some
tile glazes. Be sure to test this solution first
in a small area to see if it etches the tile or
erodes the grout.
Porcelain
Tile FAQs
Isn't
porcelain delicate and easy to break?
No. There are different types of porcelain, including
dishes and dolls, that can be very fragile. Porcelain
stone, on the other hand, is tough and long lasting
because it is fired at extremely high temperatures
(2000° F and above) until it becomes vitrified
(glass-like). This process makes porcelain stone 30
percent harder than natural stones such as granite
and marble. Prove it to yourself by trying to scratch
a piece of porcelain stone with your house keys. Or,
put a pencil under a porcelain stone, step on both
sides of the top, and rock back and forth. Ordinary
tile or stone would break - not porcelain stone!
My
porcelain sink chipped. Won't porcelain stone chip,
too? Or, what if I drop a big can of tomatoes on the
kitchen floor?
Not to worry. Your sink is merely glazed with porcelain,
so the color doesn't go all the way through like it
does with porcelain stone. With porcelain stone, there's
never a problem with wearing through the color layer.
If porcelain stone were to somehow chip, you probably
wouldn't even notice - it's the same color inside
as outside.
How
does porcelain stone compare in cost to other countertop
materials, like granite, laminates or solid surfacings?
Porcelain stone may cost more than humanmade laminates,
but it is important to compare value - not price.
On the other hand, porcelain stone costs less than
most solid surfacing products and some natural stones,
like granite. Porcelain stone delivers great looks,
an incredible range of color options, easy installation
and wipe-clean maintenance.
Suppose
I put porcelain stone on my kitchen counter. Will
it absorb stains or form mildew along the grout lines?
Porcelain stone is almost totally non-absorbent, which
means it is virtually impervious to stains and mildew.
It's the grout between the stones that you need to
be savvy about. Many countertops are now installed
with 100 percent epoxy grouts that are easy to use,
clean up quickly following installation and refuse
to stain or mildew. Otherwise, an application of high
performance grout sealer is recommended to retard
the staining of joints when using conventional sanded
grout.
I
want a real bright white tile. The porcelain stone
colors look creamy. Will they work with the white
background in my wallpaper?
Porcelain stone is made from raw materials found in
the earth that simply don't come in bright white.
Ordinary tile can be made from any kind of clay since
the body color is hidden under the glaze, whereas
white porcelain stone shows its true color throughout.
I'd
like to buy porcelain stone for my great room, but
won't it be cold?
Not necessarily. Porcelain stone is no different in
temperature than anything else in the room; it's just
that we tend to equate smooth with cold. (Of course,
cool is good in warm weather climates!) Still, it's
easy to warm things up with an area rug or two. Or,
if you're installing a brand new floor, ask your contractor
about under-floor radiant heating. Low-voltage electrical
floor warming systems are available, affordable and
easy on your heating budget.
Why
does porcelain stone cost more than ordinary ceramic
tile?
Because you are getting a superior product. Porcelain
stone requires the finest natural ingredients and
a rigidly controlled manufacturing process that utilizes
the most advanced processes and technology.
Why
are certain colors of porcelain stone more expensive
than others?
Simply because some colors cost more to manufacture
than others. The coloring agents are more expensive
and more difficult to control, requiring more technology,
time and skill.
How
do you install porcelain stone tile? Does it need
a special adhesive or grout? Do you have to seal it?
Porcelain stone is installed as easily as ordinary
ceramic tile, using the same installation tools. A
different adhesive is used with Porcelain tile than
with Ceramic tile. In most cases, your installer will
know which setting material is best, but if you're
planning a do-it-yourself project, it's a good idea
to discuss your particular installation with the knowledgeable
folks at El Dorado Tile, Marble and Granite.
What
size grout joint should I use?
The size of your grout joint is a personal decision
that you need to make. Keep in mind, however, that
larger grout joints tend to crack and attract more
dirt. Some people suggest a thinner grout joint. As
thin as 1/8" to 3/16" is best. If your design
includes stones of multiple sizes, consider using
a 1/4" grout joint throughout, which adds consistency
to the overall appearance.
How
do I keep the polished porcelain stone shining? It
looks like a lot of work.
The trick to keeping porcelain stone shining is to
thoroughly rinse off the dirty wash water when cleaning
it. Detergent residue can form a coating that's difficult
to remove, even from porcelain stone. Once you've
cleaned your polished porcelain stone, dry the floor
thoroughly with a soft cloth or a buffing pad to enhance
the shine and prevent water spots.
Granite and Marble
What
do I need to consider when buying marble or granite?
Because they are natural stones, marble and granite
are blessed with a remarkable natural beauty that
has captivated humans throughout the ages. Inherent
in such natural products is a certain lack of predictability
that sophisticated architects and designers celebrate.
Consumers who are less acquainted with the material
expect the marble ordered to be identical to the 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 an 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.
What's
the difference between marble and granite?
Although both are stones and both are 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, and is a very hard, resistant stone
made of crystallized minerals. The marble family –
limestone, travertine, marble, onyx – starts
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 beverages.
Should
I use marble or granite for my kitchen countertops?
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
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 to its original luster, taking simple precautions
and regular maintenance can save a lot of trouble
and cost. All marble an granite tops are sealed immediately
after they are installed. The impregnating substance
penetrates the stone clogging most of its pores making
its quite impervious to alcohol, juices, soft drinks,
cosmetics, cleaners, coffee, food and even oil. With
course of time, depending on how heavily the tops
are used, the sealer gets washed out. The clear indication
of this happening would be the fact that the liquids
are easily absorbed into the stone leaving temporary
(if promptly wiped off) stains.
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.
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 stone
countertops or floors. Never use any product which
is acidic; this includes substances like ammonia or
many common liquid cleaners such as Windex. You should
always use sealers and cleaning products designed
specifically for natural stone.
Granite FAQs
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.
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 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.
My
little sample of granite has pits on the surface –
will I have these on my kitchen counters?
Granite, which is crystalline in structure, always
has tiny pits – spaces between the various mineral
crystals. You don’t see them on a larger piece
because the overall appearance is polished and mirror-like.
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 humanmade.
How
do I clean my granite tops?
POLISHED GRANITE is a very durable stone, much harder
than marble. Polished Granite should receive the same
cleaning care as polished marble, using a mild phosphate-free,
biodegradable liquid dish-soap, soap flakes or powder
which contain no aromatics, followed by a through
rinsing and drying with cotton-flannel or chamois.
Will
my granite look like the sample?
Granite is a natural material with naturally occurring
variations in color, tone, granularity, pattern, etc.
These variations are expected and are the source of
its natural beauty.
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, may show a dark spot
when the water is wiped away. This spot will then
dry up and no evidence will show. Only a few colors
demonstrate this trait.
Can
I set hot pot on my granite countertop?
Granite is formed by extreme heat and pressure combined
beneath the earths crust. It can not 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.
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.
Can
granite seams show?
Because granite is a natural material and is mined
from the quarry in blocks usually no more than 10'
long, 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 will show
more seams than a uniform pattern. Most customers
have found that the beauty of natural granite outweighs
the concern of seams.
How
are seams made?
Seams are done where the granite joins with a smooth,
straight cut. During installation, a small bead of
silicone is placed along the seam to seal it. Occasionally,
in areas of stress or without sufficient support,
the seams will be joined with epoxy, which must be
supported temporarily until the epoxy cures.
Can
granite crack?
Not with the ordinary use. Granite is most susceptible
to cracks during shipping and installation. Normal
use will not overstress this durable material.
Can
granite cantilever?
You can cantilever granite up to 14" 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.
Marble FAQs
Can
I use marble on my kitchen counters?
Yes. In fact, marbles that have a honed finish will
not etch because its surface starts out with a matte
finish. Because marbles (and limestone and travertine)
are calcium carbonate, the polished surface is more
vulnerable to household acids including vinegar, mustard,
catsup, citrus and a host of other food-related products.
These acidic substances cause a chemical reaction
which will remove the polish.
Is
marble really appropriate to use in kitchens or high-traffic
areas?
Yes. Since ancient times, marble has been used in
all areas of the Grecian home; from furnishings to
floors. These Greek marbles have proven as durable
as materials traditionally considered to be sturdier
with the added benefit of creating a warm welcoming
atmosphere.
Can
I cut on marble?
Marble is a more porous material and therefore likely
to be damaged by a sharp object.
