FAQs About Using Stone In Your Home

1. Q. IS NATURAL STONE A GOOD CHOICE FOR HOME USE?

A. YES.  Natural stone is a terrific (not to mention beautiful) material to
use in all areas of your home.  Knowing the different types of stone,
their finishes and applications will help you to make an informed
decision on which stone is the best for your project.

2. Q. CAN YOU EXPLAIN THE DIFFERENT FINISHES FOR STONE?

A. There are many finishes and options available.  Here are the most
widely used:

• Polished -- A high gloss surface.
• Honed -- Smooth with squared edges and without a polished
  surface.
• Tumbled -- Lightly tumbled to achieve rounded edges and a
  surface that is not as smooth as honed.
• Antique Tumbled -- Medium tumble edges and surface to achieve a
  slight rustic look.
• Cobbled or Distressed -- Heavily tumbled edges and surface to
  achieve an aged or ancient look.
• Brushed -- Acid washed and wire brushed for a smooth textured
  surface.
• Flamed -- Blow torched for a rough textured surface.

3. Q. DOESN'T STONE STAIN? I DON'T WANT STAINS!

A. YES.  All natural stone can stain and etch (a dull spot in a polished or
honed surface), including GRANITES. Sealers DO NOT prevent
staining as they are a moisture barrier only, yet they will help to give
you a small amount of time to wipe up spills.  It is nearly impossible to
prevent staining or etching, but serious stains can be almost
completely removed and any etching can be resurfaced if either is
truly bothersome to you.  To help keep a perspective on choosing to
use natural stone, remember the following:

1. For centuries, many European countries have used
natural stone from floor to ceiling, inside and out.  The
stone becomes stained, cracked, pitted?and that is why
we love it! These characteristics only make it that much
more beautiful.  (Only we Americans get uptight about
such things!)
2. Because stone is quarried from the earth and not "man"
made, it is improbable to ever find two exact matching
tiles or matching slabs for that matter. One slab may even
look different from each end of itself.  That is also the
beauty because each piece is different, but when pieces
are put together as a whole it is a masterpiece!  (Be sure
to purchase enough to complete your project as you may
not be able to get more from the same lot.)
3. Stone is timeless.  It does not get dated like the 70's
Avocado Green and Harvest Gold décor did.
4. Stone will last longer than any of us will. There are
centuries old castles, made of 100% stone and still
standing today!
5. It is a natural resource that will never run out.
6. The more it is used, the faster a "Patina" (light sheen on
the surface) will develop.  The "Patina" will also aid to
prevent staining to a lesser degree.

4. Q. WHAT IS THE BEST STONE TO USE IN MY HOME?

A. It is really a matter of choice and the look you want to achieve.  Ask yourself the following questions when making your decision:  Is it
beautiful to me? Do I love it?  Could I live with it for years? 
The best advice that I can ever give to anyone choosing stone is:  Go
with what you are drawn to from the beginning.  First, because you
will only spend a lot of time and become confused when laboring over
the "right" decision by looking at many different stones and colors;
secondly, you will probably not be happy with your selection if you
have to settle on something else; and finally, you will more than likely go back to what you liked the first time.  Reviewing the following most used
stone types will help when you are ready to make your choice.

• GRANITES -- Granites usually have a "spattered" or "swirled"
  grain and can contain many colors (minerals).  Generally, granites
  have a polished finished and have a "busy" look, but to keep up
  with current trends, more manufacturers are producing honed
  (smooth & unpolished) and flamed (rough textured) surfaces. 
  Granites may be purchased in slab and dimensional tile form and
  can be used in almost any application. It has become ever popular
  as it is being used frequently in newly built tract housing,
  apartment/condominium complexes and commercial buildings. 
  Granites are imported from many countries and have just as many
  colors and sizes to choose from.  A note in using polished granite is
  to know that it can be slippery to walk on until a patina builds on
  it.  As with any other commodity, stone is also graded for quality
  standards.  Be wary if it is extremely inexpensive?(less than $7.00
  per square foot unless you are buying a large quantity.)  The price
  ranges in granites can be anywhere in between $8.00 to $90.00 per
  square foot, depending on the color, rarity and where the stone
  comes from.  The "blue" stones, containing minerals/gems such as
  sodalite are usually in the higher priced ranges.

• LIMESTONES - There are many types of limestone available and
  vary to many degrees, depending upon where it comes from. 
  Unpopular to belief, limestone is also a perfectly suitable stone to
  use in all areas of your home.  Most limestones have softer earth
  tone colors; may contain a "swirl" veining movement throughout;
  can contain fossils; or may have a light speckled grain. 
  Limestones, just like granite or any other natural stone can stain,
  etch or get scratched, but again, you should not use natural stone
  if this will bother you. Limestone also is widely available in
  dimensional tile and slab form. This stone is used most frequently
  in higher-end homes, architectural designs and commercial
  applications as it is easy to work with, the colors are muted
  compared to granites, it is available in as many finishes and
  textures as granite and it is still relatively new to the market. It is
  still considered to be a "custom" choice, as it has not reached the
  overuse level of granite. Some limestones from countries such as
  France and Portugal can be somewhat porous but are perfect for
  flooring, backsplashes, fireplace surrounds and outdoor uses. 
  Limestone from countries such as the US and Israel (Jerusalem
  Stone) are generally heavier and usually as dense as granite, which
  makes it suitable for almost every application.

• SLATES - Slate used to be used mainly for chalkboard, billiard
  tables, science lab areas and roof tiles.  However, in recent years it
  has become more popular for residential use in most applications,
  with the exception of fabricated counter tops.  Slate tiles are
  generally rough in surface texture, with the exception of the
  tumbled version.  Most slates are available in a wide variety of
  sizes in dimensional tiles; a few in slab form and most can be
  gotten in crates of random pieces like flagstone. It is a perfect
  stone for water areas such as showers & spas, patio/driveway
  areas, pool surrounds and roofing applications. Most slates
  contain a huge variation of color, even within the same lot and
  some will even look to have been stained from spills of red wine,
  which is not the case. This is caused from earth minerals such as
  iron and only adds to the beauty of the stone. Slate holds onto heat
  well, which is another reason besides being fire proof; it is widely
  used as roofing material. (Use light colors in outdoor areas where
  you may be walking barefoot!)  Since slates have a softer property,
  be aware that it can shale off the surface more easily.  This will not
  harm it per se, but may cause you concern if you are not aware
  that it happens. One of the difficulties of slate is that it is varied in
  thickness. Because of the shale properties, it is very difficult to cut
  evenly.  Generally, manufacturers will cut them with a "gauged"
  thickness or "sawn back" treatment, leaving one side smoother. 
  Because of the varied thickness between each piece of tile, specific
  sized installations may be more of a challenge, so expect your
  installer costs to be a bit higher. Slate itself is generally a less
  costlier stone. Expect anywhere from $4.00 - $8.00 per square foot,
  dependent upon the grade and country of origin.  Again, beware of
  any extremely inexpensive prices and be sure to check the quality
  of the slate to be sure that it has not been filled with dyes. Test by
  holding a piece under running water for a few minutes and also by
  putting a few tablespoons of vinegar or lemon juice on it and
  wiping off.  If any color comes off, return it immediately! Just a
  note: I only recommend using any acidic solution on stone in this
  instance for testing purposes only.

• MARBLE - Most people are familiar with marble in many uses.
  From Greek statues to Roman baths, marble has been used for
  centuries in just about every possible application, both interior
  and exterior.  Marble has the same general properties of limestone
  and can stain, etch or scratch, but it only becomes more beautiful
  over time and use.  It is readily available in just about every color,
  size, finish and texture known to man.  Most marbles have a
  veining of a mineral throughout them and are generally thought to
  be from Italy, but it in actuality it is quarried from all over the
  world.  Tumbled marble has become extremely popular in the
  United States in the last few years for backsplash, flooring and
  shower areas.  Prices range from $6.00 - $30.00 per square foot,
  again dependent upon the rarity, color and country of origin.  A
  couple of drawbacks to marble to be aware of is: 1. Green marbles
  containing serpentine need to be installed in water areas with
  specific setting guidelines that your installer should know of as
  water can warp and break apart green marbles; 2. Polished
  marble can be slippery to walk upon until a patina has built up on
  the surface.

• TRAVERTINE - Travertine is marble, except it is filled with
  "holes."  To understand what causes the holes, think of it this
  way?wherever a river or stream was prior to the marble being
  quarried is where you will find travertine.  Because of the holes,
  people can be scared off because travertine is generally thought to
  be more porous and not suitable for residential use.  This is not the
  case, as all of those holes become filled in with grout during
  installation, giving it a very unique look.  The same travertine can
  be used in two separate areas but appear another way just by
  using two different grout colors!  Travertine can be purchased
  with the holes pre-filled, but in my experience with it, I don't
  recommend it.  In general, the epoxy fill that is used has a color to
  it that does not look natural to the stone and it has a tendency to
  come out after a short amount of time in high traffic areas.  Expect
  to pay anywhere from $5.00 - $15.00 per square foot.

5. Q. IS STONE MORE DIFFICULT OR COSTLY TO INSTALL THAN
CERAMIC TILE?

A. On the whole, it is not more difficult to install.  There are exceptions
of course such as the difficulties with thickness gauges, which takes
more time in planing the layout and whether a complex pattern is being used.  As for cost it is generally not more expensive except for time spent on laying out patterns and the thickness gauging again, at least for the tile contractors I have worked on projects with.  The setting supplies and procedures are the same, but stone is heavier to work with.  I suggest talking it over with your installer and also taking the time to look at previous jobs he or she has installed if possible.  I will be giving tips on selecting a tile contractor/installer in my next article. 

6. Q. CAN A STONE DESIGN BE USED OR MIXED WITH OTHER
KINDS OF MATERIALS?

A. Absolutely!  The possibilities are endless.  You can incorporate stone
with ceramic, porcelain, glass, and terracotta?anything you can
think of, even mixing different types of stones together.

7. Q. HOW DO I FIGURE THE QUANTITY THAT I WILL NEED?

A. Generally, tile and stone for a "field" area (space where plain tile will be) is figured by the square foot.  To figure square footage, measure the area that you will be putting the tile with a tape measure.  Examples:

1. You measure your room and it comes out to be 10-1/2 feet
wide by 15-3/4 feet long?you would calculate it by
multiplying 10.5x15.75 = 165.38.  Round this number off
to the closest whole number (165).  I suggest adding on a
10-15% overage to plan for cuts, breakage and a little
extra to store in case a piece needs to be replaced later in
time.

2. You measure your wall area to be covered and you get
18" tall and 33" long.  Multiply 18x33 = 594". Now divide
that number by 144, resulting in 4.13sf. (There are 144 sq.
inches per square foot). Again, round it off and add on
for overage.

When figuring for decorative tile or trim, it is usually by the piece
and calculated by the lineal foot.

For slabs, it is best to let your fabricator figure the quantity for you.

8. Q. WHAT SIZE GROUT JOINTS SHOULD I USE?

A. Again, this is a matter of choice and the look you prefer.  Honed stone
can usually be butt-jointed (tight to each other) with very little grout
showing if you want to see much grout or grid pattern; tumbled stone
usually has a 1/8" to 1/4" grout joint which will show off the edges
more.

9. Q. WHAT SIZE OF STONE TILE SHOULD I USE FOR MY
PROJECT?

A. It depends upon the project itself and the area size.  Something to
keep in mind is that if the area to be tiled is small, it is better to use a
bigger size tile, if you want the area to appear larger.  It is not
uncommon to believe that if you have a small perimeter of floor that
you should use a 4", 6", or 12" tile, which is not necessary. When
doing so, it will make the area feel small and you will have more grout
joints.

10. Q. I DON'T LIKE THE GRID PATTERN I SEE FREQUENTLY. 
WHAT CAN YOU SUGGEST FOR AN ALTERNATIVE?

A. There are many pre-set repeating stone patterns available, or you can
make your own "random" pattern from different size pieces of stone. 
A pre-set pattern is easier to use and the amount of stone that will be
needed for the project will be easier to figure.  To also help from
keeping a grid pattern from being so obvious is to use a grout color
that is as close as possible to the color of the stone. Using dark grout
with light tile, or light grout with dark tile was a popular look in the
80's. However, I think it is better to see as little grout as possible.  Your stone is the expensive part of your project so you should want to show it off, not your grout!

11. Q. CAN YOU HELP ME WITH DESIGNING MY STONE LAYOUT?

A. Yes, I can.  I charge an hourly fee of $75 and I will need several things
from you:

1. A copy of your blueprints, including the elevations if you
have them and the area to be tiled clearly marked; or a
drawing of the area, including the dimensions and the
area to be tiled shown. Make sure to specify what
room/location it is, if it is not marked on the blueprint.
2. The style of home you have; or the look you prefer,
i.e.?rustic, contemporary, elegant, traditional?
3. Whether or not you have already chosen your stone.  If
so, what did you pick and what size? If not, do you want
me to make suggestions for you? If yes, do you have a set
budget?
4. Will you want to use decorative trim pieces? If so, did you
choose one yet? What are the dimensions of a piece(s)?
