Tiling Over a Tile Floor
Ask Danny, Flooring by Danny Lipford
I currently have a dated ceramic bathroom tile floor originally installed over a cement and mortar base. The ceramic tiles are about 6 inch square with a matte finish and about 1/4″ thick with 1/4″ sanded grouting. Is it possible to tile on top of the existing tiles with thin set mortar? If so, are there any preparations to the existing tiles required? Your advice would be appreciated, James
James,
Yes, you can lay tile over an existing tile floor as long as it is in good condition with no major cracks or settling. Keep in mind, however, that it will raise the height of the floor, which might require cutting off the bottom of the bathroom door. You will also need to take the toilet out before installing the tile and replace the existing toilet flange bolts if they aren’t long enough for the added height. If any of the old tiles are loose, reattach them to the floor, and fill in any missing spots. After cleaning the floor thoroughly, lay the tile with thin-set adhesive. For more detailed information on how to tile over tile, check out the online video from our Bathroom Makeover show.

what about putting ceramic tile or wood laminate over existing sheet linoleum? Need some kind of wood base to make level?

I am considering tiling over a concrete slab that I have on my back porch. The slab currently has moisture issues at the change of seasons (I live in Wisconsin and there is moisture present when there is a thaw). How should I treat the area prior to application of tiles to prevent moisture from coming thru the floor?
Thanks
