Lay tile on concrete by preparing the concrete, applying thinset, laying the tiles, cutting the tiles and adding grout. You need chalk lines, tile spacers, a paintbrush, tile, a notched trowel, thinset, a wet saw, grout, a grout float and waterproofing membrane material.
- Prepare the concrete
Sweep the concrete. Paint a coat of anti-fracture and waterproofing membrane material on to the concrete. Once it dries it creates a rubber-like coating.
- Snap chalk lines
Lay tiles over a 2-foot section of the cement. Measure the section, and mark the measurements against the wall. Use the measurements to snap chalk lines in a grid over the floor as reference when laying the tile.
- Prepare the thinset
Use cold water when preparing the thinset. Follow the instructions on the label.
- Apply the thinset
Apply a layer of thinset using a notched trowel to a section of the floor.
- Lay the tile
Using the chalk line as a guide, press a tile into the thinset. Place tile spacers on the corners. Continue this process until you have laid all the tiles.
- Cut tiles
Cut tiles using a wet saw to fit along the edges or any obstructions on the floor.
- Apply the grout
Use a grout float to apply the grout to the spaces between the tiles. Remove the tile spacers as you go. Wipe away excess grout using a damp sponge.
