My wife dislikes our floor tile in one of the rooms. So is it ok to put new floor tile over old floor tile? I don't want the mess of removing the old tile.
I always thought not a good Idea but Pat, I found this Page for you and from it you may get the Information you need. Best of Luck Google
If this is a room with entry doors and or cabinets you may have to trim the bottom of all doors to accommodate the higher floor. Also if this adjoins another floor you will have a small step to deal with after doing this. Just some thoughts.
We installed tile on tile recently. City Hardware sells a type of acrylic paint to apply to the old tiles prior to installation of new tiles. I had a small learning experience with large tiles (80 x 80)cm. The darn things were not flat so they are uneven. If I had graded them for flat, concave or convex the results would have been better.
