Creating The Substrate Needed to Tile Over Tile

Step 1

Please be sure to wear your safety goggles while removing tile grout and breaking up tile. Flying pieces from breaking up tile can do damage to your eyes.

Use a grout knife and remove the tile grout from any damaged tiles. Break the damaged tile using a hammer or a small sledgehammer and a cold chisel. Crack up the tile working from the center to the edges of the tile.



Step 2

Remove the broken pieces of tile, Use your margin trowel or putty knife to scrape up all the fine pieces. Scrape off any tile adhesive remaining in the recess and dust out or vacuum the area. You are doing this so your new thinset can bond securely with the floor.



Step 3
If possible use the same tile adhesive in the recess as the original tile mastic or tile thinset.
Use your margin trowel or wide putty knife and apply tile adhesive into the recess area





Step 4

Using your margin trowel or putty knife back butter your replacement tile and push the it into the recess area, until the tile adhesive oozes up from the tile grout lines.

Make sure your replacement tile is level with the rest of the floor. Then wipe off the excess thinset and let it .cure



Step 5


You'll want to abrade the tile surface so the adhesive will stick well and the new floor tiles will bond to the surface.
So use a sanding block and a course grit of abrasive paper to roughen up the entire surface of the tile surface.



Step 6

Use a margin trowel to spread a thin layer of thinset over the entire surface of the floor. Make sure the grout joints are level with the surface of the tiles.

You now have your substrate for installing your tile over tile
