Create your own style of pebble tile for use in bathrooms in areas such as the shower stall floor and bathroom walls. Pebble tile sheets come in many styles and are sold by retailers for do-it-yourself installation. More ambitious do-it-yourselfers can make their own tile mosaics. Purchase bags of pebbles at a garden or home improvement store, or look for interesting stones around the yard, at the beach, or in rivers, brooks and streams. Adding a few coloured shiny marbles or beach glass is also an option.
Remove all existing tile and sand the wood. If you are looking to make a pattern on your floor or wall, draw out the borders of your design in pencil on the bare wall or floor.
Prepare the mortar in a large contractor's bucket by following the manufactuer's instructions. Mortar is ready to use when it is the consistency of thick pudding. Spread a 1-inch thick layer of mortar on the bare wood using the trowel. Then use the combed end of the trowel to create ridges in the mortar that will give the pebbles traction so that they stick better.
Start laying the pebbles in the wet mortar. Tap down the pebbles by using the wood plank to ensure that they have sunken into the mortar. Continue the process until you have finished your pattern. Periodically wet down the pebbles with a damp sponge as the mortar is drying to help the curing process and clean the pebbles from any excess mortar. Wait two to three days for the mortar to completely cure.
Cover the pebbles with sealant once they are set. Apply the sealant to moistened rag and wipe it over the mortar and pebbles. Continue with buffing the sealant over the pebbles and into the mortar until it is no longer visible. The sealant will provide shine and a finished look to the floor or wall that you are covering and prevent the pebbles from dislodging.
