Installation

GBM glass tiles can be used in heated areas such as steam rooms, showers, saunas or hot pools.
The proper installation of GBM glass tiles is critical to avoid stress on the glass.
CUTTING GLASS TILES
The easiest, fastest and best way to cut our glass tiles is with a simple glass-scoring tool and a
straight edge. IMPORTANT! All cut edges on GBM glass tiles need to be embedded completely with
the setting material. To cut, score the glass lightly on the front or unpainted side of the tile along the
desired cut line and snap along the line. To snap the tile, place the tip of a tapered hardwood dowel,
similar to the size of a pencil, directly under the edge of the scored line and place even pressure on
both sides. Carbide wheel glass-scoring tools are available at nearly all hardware stores. A very
useful and important tool for all glass tile installations is a pair of GLASS RUN PLIERS. Using glass
run pliers allows the installer to easily cut and trim G.B.M. glass tiles. Cuts as thin as 3/8” or smaller
are possible.
Once the tile surface is scored, the score line is aligned with a white stripe on the top of the pliers
jaw. Slight pressure applied to the pliers will snap the glass. When score cutting, be sure to use the
Glass Run Pliers to affect the initial cutting of the glass. Then, while holding the tile face up, separate
the tile with a downward motion allowing the cut edge to sever the tile membrane.
GBM. glass tiles can also be cut with a wet saw. If using a wet saw, be sure to use a glass
compatible diamond blade in good condition. A blade for cutting glass has smaller diamonds than a
tile blade and has a continuous rim. Most blades designed for ceramic tiles are coarse and will chip
the glass. It is very important when cutting glass with a wet saw to have adequate water flow and to
cut slowly. It is best to practice making a few cuts with regular 1/4” window glass before proceeding
to cut the tile. A lapidary blade will also make a very clean cut on glass.
When cutting glass tile on a wet saw, it is required to cut the tile face down. This will prevent
chipping of the colored areas of the tile. A piece of electrical tape, masking tape or duct tape laid
along the line of the cut on the tile face will greatly reduce chipping along the edge. A light piece of
cardboard or building paper on the saw bed will protect the surface of the glass from scratches.
All edges must be sealed with an epoxy grout system to ensure complete protection to the tiles.
Edges of the cut tile can be chamfered with a diamond hand pad. Hand pads and related glass tile
cutting tools are available through 3M Corporation as well as a variety of other glass tool distributors
found on the Internet. Silicon carbide sanding belts may be used if the belt is dressed with a light
coat of silicone spray.
CLEANING
GBM glass tiles can be routinely cleaned with any non-abrasive cleaning compound or formula that
is recommended for both glass and tile. Follow rinsing instructions carefully. DO NOT USE acids to
clean GBM glass tiles.
