Installation
It is recommended to use a white thin-set mortar with a exible acrylic additive (or a white polymer fortied
thin-set mortar). Apply this mixture with the manufacturer’s recommendations of a notch trowel (typically
3/16”x3/16” V-notch and then knock down the trowel ridges with the at side of the trowel to produce an
even layer of thin-set mortar). Spread only enough thin-set to install a few sheets at a time. Back-butter each
sheet with the at edge of the trowel. Be sure to achieve full coverage on the back of the tile to avoid the
notch marks in the thin-set from showing through the glass. Carefully, press into the thin-set leaving even
spaces in between tiles. A grout oat can be used to tap the tiles into place. We recommend to allow a
1/8” joint between tiles. Allow for movement joints where the tiles abut restraining surfaces and around the
perimeter of the installation. Grout with an unsanded grout, to prevent scratching, after the adhesive has
had proper time to cure according to the manufacturer’s recommendations.
Cutting
A ceramic tile cutter is not recommended. Use a wet saw with a diamond blade designed for cutting
glass. It is important to use the proper blade because blades designed for ceramic tile will chip the glass.
A porcelain continuous blade is best suited for cutting glass and is available in multiples sizes. Whenever
possible, cut edges should be placed in corners where they can be hidden.
Drilling
Use a drill bit that is especially designed for glass. The glass tile must be securely clamped into place to
prevent movement of the tile during the drilling process. When drilling the hole, keep the bit and hole
lubricated to prevent chipping. Drill from both ends of the tile, starting with the back and drilling half the
depth of the tile. Then, turn the tile over and complete the hole. This will prevent the glass from chipping as
the drill bit exits the tile.
Cleaning
It is recommended to use a non-abrasive cleaner to prevent scratching of the tile. Tiles that have been
scratched prior to or during installation are the customer’s responsibility.
