Clear the area on which you wish to glue down a ceramic tile with a wire brush and putty knife. Chip away any pre-existing mortar or glue with the putty knife and sweep away the debris with the wire brush.
Mix 2 cups of the tile mortar with 1/3 cup of water in a small plastic bucket. Integrate the mixture until the consistency is smooth. This amount will be enough for one, 8-inch tile. Mix more for extra tiles if needed.
Allow the mortar to stand for 10 minutes.
Scoop the mortar into place with a pointed trowel.
Spread the mortar so that it is 1/4 inch thick in all places. Rake the mortar with a 1/4 inch notched trowel.
Firmly press the tile into place.
Place a wood block on top of the tile and gently hammer the block with the rubber end of a hammer to set the tile.
