How to Lay a Pebble Floor
If you like the look and feel of pebbles instead of tile, learn to do it from start to finish.
Proper Subfloor
Before you start, make sure you have the proper sub-floor installed. Proper cement board, or ditra underlayment down.
Dry Set the Pattern
Lat out the pattern of pebbles before you place them. Make sure the fitting is as natural as possible.
Set Tile
Use a trowel, and apply an even amount of thinset (no thicker than 1/8"). Lay the pebble tiles down, interlocking each tile on all sides, starting at the edge.
Fill in the Gaps
Take some pebbles off other sheets that haven't been laid down, and place them into gaps along the edges. Don't cut the sheets; they'll look much worse.
Apply Sealer
Apply a coat of sealer to prevent the stones from absorbing grout color. Follow the instructions on the sealer.
Grout the Floor
Mix the grout to proper consistency, then start applying it in small sections. Start in a corner. Make sure to pack the grout between the pebbles, and apply it liberally. Allow it to sit for 20 minutes, then wipe it away with a damp sponge. Rinse the sponge in clean water, and repeat until all excess grout is gone. Wait 24 hours for the grout to dry, then apply a final coat of sealer. Enjoy your new floor!
