Tile adhesive, also called thin set or tile mortar, is a kind of construction material that used to affix tile to a surface. For best results, avoid using too much adhesive or spreading too much adhesive on the substrate at one time. Limiting the spreading of tile adhesive to enough of a surface area to lay two or three tiles at a time will prevent the tile adhesive from drying too soon before you have a chance to adhere your tile. Make sure to work in a well-ventilated space.
- Follow the manufacturer’s directions to prepare enough tile adhesive to be used within 30 minutes. This will prevent the adhesive from drying. If you have tile adhesive that requires no further preparation you can skip this step.
- Use a trowel to take a glob of tile adhesive out of the container and drop it on the surface. You can also dip the trowel into the tile adhesive so a glob of adhesive rests on one of the corners of the trowel.
- Use the notch of the trowel to spread tile adhesive to cover the surface area of one to three tiles. Hold the trowel at a 45-degree angle as you spread tile adhesive so the adhesive will set an even height. For best results, move the tile adhesive in a direction that is diagonal to the ridge pattern on the bottom of your tile.
- Apply one tile at a time before the tile adhesive has an opportunity to dry. This should be done within a few minutes. Use plastic spacer to leave joint between tiles to apply tile grout if necessary.
