Pebble tiles consist of a mesh tile covered with pebbles in various sizes and colours. The mesh sheet makes installation much easier as you do not need to place each individual pebble on the surface, which can be a time-consuming project. These tiles often have a slightly irregular shape that allows you to fit them together like puzzle pieces to seamlessly cover any surface.
Place the pebble tiles on the surface. Cut along the mesh as necessary with scissors so that the sheet of tile fits in the space. When you are happy with the appearance of the tiles, remove them from the surface.
Spread a 1/4-inch-thick layer of ready-to-use tile mortar onto a two-foot square area with a notched trowel. Turn the trowel and comb through the mortar with the notched edge to create grooves in the wet mortar.
Lay the pebble tiles onto the wet mortar immediately. Gently tap on the top of the pebble tiles with a rubber grout float to secure them to the mortar.
Fill in any empty spots around the edges of the pebble tiles by cutting individual pebbles from a spare pebble tile or from scrap pieces you trimmed away earlier. Press the individual tiles into place on the wet mortar.
Tile the area in two-foot sections by spreading the mortar and pressing the pebble tiles into place. Let the mortar dry overnight or according to the directions on the mortar's packaging.
Apply a tile-sealing product to the surface of the pebble tile with a clean sponge and let the sealer dry according to the product's instructions. Use tile sealer and not grout sealer because they are two different products. The sealer will prevent grout from sticking to the pebble tiles and make cleaning much easier.
Mix dry sanded grout in a bucket with water, according to the directions on the packaging. The grout should be the consistency of thick mud.
Scoop some of the grout from the bucket and place it on top of the pebble tile. Spread the grout around with a rubber grout float to fill in the crevices between the pebbles. Don't worry if some of the grout remains on the face of the pebbles. Continue until all of the pebble tile has been grouted. Let the grout dry for approximately 30 minutes.
Scrub the pebble tiles with a stiff brush to remove excess grout from the surface of the tiles. Try to avoid dislodging chunks of grout from between the pebbles.
Clean the face of the pebble tiles with a damp sponge to remove any remaining grout. Rinse the sponge as necessary in clean water.
Soak up any visible water left behind after cleaning with a sponge and let the grout dry completely.
