Install Glass Tile on a Countertop Install Glass Tile on a Countertop

When remodeling a kitchen or a bathroom, choosing glass tile can bring counter tops back to life. It is not that much harder to install glass tile than it is for regular tile, except for a few details. It is important to carefully choose and install the tile because it is going to be there for a long time.

Preparing the Surface

Before to begin the tile installation, the counter top must be prepared to receive the thin set. If an old counter top was removed, a new counter has to be rebuilt with plywood that is free of paint or glue.

Deciding how to make the edge of the counter top has to be done before laying the tile. Installing a wood molding all around the counter is an easier option to prevent breakage than making it of glass tile.

Preparing the Mix

Mix some thin set powder in a pail to until getting a non liquid thick mixture. Use a sponge to wet the plywood before applying the thin set. Otherwise the plywood will absorb the water in the thin set and cause it to dry too fast. Since glass tile is transparent, the white color of the thin set will be seen through the glass. A different color can be obtained by mixing some sanded grout within the thin set.

Installing the Tile

It is better to apply about 3 foot square of thin set at a time with the straight edge trowel than to do the whole counter top to prevent the mixture to get dried too soon. Install the tiles starting at the edge of the counter top going towards the back splash wall. That way if a cut has to be made it will be out of sight.

Using spacers is important to make sure the spaces are nice and straight between the tiles.  It is better to use a sanded grout to fill the joints on a counter top so the spaces between the tiles should be not less than 1/8 inch. The joints should be cleaned of any excess of thin set between the tiles with a wet sponge.

Applying the Grout

After the installation is completed, the tiles must be allowed to dry for 24 hours before removing the spacers. When ready, mix sanded grout with a small amount of water in a pail. A mixture that gets the consistency of Elmer's glue works perfectly.

Apply the grout with a soft rubber trowel and let dry about 10 to 15 minutes. Then clean the tiles with a sponge twice. If a wood molding needs to be installed at the edge of the counter top, it must be done before applying the grout. Then the wood trim can be finished with a lacquer.

After the excess of grout is cleaned off, the joints between the tiles should not be touched to avoid marks to be made in the soft grout. It takes another 24 hours before it gets completely dry.
