How to install new tiles over old tiles on walls.

If you plan to do this backsplash project over existing tile you will have to make some modifications. If they do simply make the spaces smaller or eliminate them altogether. If the old tiles are in bad shape the new tiles won t adhere correctly. In the case of a floor this could cause both layers of tiles to lift up.

Seal the walls with a skim coat and let it dry thoroughly. Grind them down with a grinder. Using a modified mortar with latex or polymer additives creates a stronger bond between the existing tile floor and your new tiles. And third let this coat dry for 24 hours.

Use liquid nails and pay attention to the spacing to see if your tile and grout lines show through. Position your tiles according to the layout you choose. Prepare the surface for installation. No matter whether you are tiling over tiles on a floor or a wall your new tiles will need a stable base.

Second apply a very thin coat of thin set mortar filling in the current grout lines. Strip them all off and start again it simply is not worth the risk. Try and lever the old tiles off. Sand with a medium grit sandpaper to create a uniform surface that s not too smooth.

If they move or come off do not tile over them. Mix degreasing cleaner with water in a bucket using a dilution recommended. Thoroughly vacuum the area and give the wall a once over with a damp sponge or cleaning cloth. First clean and then sand the surface of the old tile until it feels rough.

You want the tile adhesive to have something to grab onto. Lay a level on the old tile and mark any high spots. The basic tiling process is the same as any tile installation. Roughen the tile with 80 grit sandpaper.

If your old ceramic tile is worn or dated you can lay new tile right over the old and avoid the huge job of tearing out the old tile. This provides a more even foundation for the new tiles to adhere to. Tiling over an uneven surface will give you less than stellar results so level out any globs of dried grout with a sander and secure loose tiles with fresh.
