- 1). Dry-lay the tile sheets along the installation area. This will give you a good idea of how many tile sheets you'll need and where they should be cut. In many cases, it will be easier to find and mark a center line and work out from that line. Once you decide on a layout for the tile sheets, mark a starting point with a pencil so you know where to begin applying thinset mortar.
- 2). Apply the thinset mortar. Place the mortar on the area with a ¼-nch V-notch trowel. Use the notched edge of the trowel to create ridges and remove the excess. After the ridges have been created, use the flat edge of the trowel to slightly smooth the ridges. This is especially important if you are working with glass tile sheets because ridges will show through the glass tile after they are installed.
- 3). Press the tile sheets gently into place. If you are installing the tile sheets on a wall, work from the bottom of the wall upward. Evenly set the tiles with a block and a hammer. Place the block on top of the tiles and gently tap the block with the hammer. This should ensure that all of the tiles are set into the mortar.
- 4). Remove the paper facing with a damp sponge. Wait approximately 30 minutes before trying to remove the paper facing. As you remove the facing, make sure it is dampened and then slowly remove it in a diagonal direction. Let the thinset mortar dry for two days.
- 5). Grout the tile joints with an epoxy grout float. Run the float over the tile diagonally to remove the extra grout. Use a damp sponge to remove the grout haze from the tiles. The grout should be allowed to dry for 24 to 48 hours.
