About Natural Stone
A natural characteristic of granite and marble is its inherent lack of
uniformity. Because it is a completely natural material, it can have a
great deal of variation in color, shade, nish, tint, hardness, strength,
and so on.
Any time you use natural stone, you can always expect differences
from one tile to the next. You will frequently see dry seams, pit or fos-
sils. These areas are often lled in at the factory. Over time through
normal use, the ll may work its way out.
Even though stone tile is a natural product, it nevertheless can be af-
fected by extremes in weather. Both marble and granite are decorative
and durable, but they have different compositions and wear differently
in the elements.
We recommend barbecue island owners keep their island covered if
they are concerned about damage from constant exposure to weather.
This is particularly true in areas where there is snow, ice, or very hot
weather.
Stone is porous, especially marble, and often has natural ssures in the
surface. Constant exposure to extreme heat or cold can cause these
natural features to expand and eventually crack.
Although the stone has been properly nished and is suitable for use in
an outdoor environment, Cal Spas does not apply a weather sealant to
our countertops. We never wish to second-guess how our customers
want to use their barbecues or the locale they will use them in, so we
leave the choice of applying a weather sealant entirely up to owners.
We do not recommend any specic brand or manufacturer, although
there are literally hundreds of excellent products on the market cus-
tomers may choose from.
In addition to maintaining the stone tile surfaces, barbecue island own-
ers need to know that the grout between the tile, while it is durable,
can also be affected by both extremes in weather and by normal use.
Grout is much easier to repair than stone tile and gaps between the tile
can cause water to seep into the barbecue island and cause damage
to the interior.
In those instances where natural cracks occur, we recommend having
an experienced tile worker lling them with a material of a complemen-
tary color. After the ller sets and is sanded smooth, apply a weather
sealant to help prevent further cracking.
