How do I install new peel & stick tiles over existing ones?

Hello Karen! If you already have 2 layers of peel and stick tiles and it seems fine you should be able to remove the first layer and then add more. You might find that you can't remove just the first layer--that adhesive is very strong! Of course it would be better to remove ALL the peel and stick tiles first. They can be tough to remove. I have used a heat gun to soften the adhesive so the tiles can be pulled off easier. You have to be careful with the heat gun. Move it back and forth across each tile to heat up the tile and then have a board to lay the hot heat gun on while you are pulling up the tiles. You can only do a few at a time. It is a tedious job but if you keep at it you can remove all the tiles.

Should remove all the tile to install new. Any imperfections in old tile will transfer to new tile. Also too much weight can cause all tile to separate from the wall. Seems like that has already happened with the two layers you already have.

I have done it before. I added peel and stick vinyl squares over existing sheet vinyl floor in a guest bathroom. Be sure to strip off any wax and maybe scuff up the floor. Definitely get rid of old layer of tiles. Mine stayed OK for many years - a little slip where pressure was applied due to foot traffic after a few years. I eventually pulled up all flooring and laid ceramic tile during a remodel.

Hi, Karen!

I would definitely remove the existing tiles first. Then clean with a degreaser or TSP prior to putting new tiles down. Using a hair dryer or a heat gun set on low definitely makes it easier! I hope this helps!

Yes, it does. Thank you so much.

If you can get the old up and clean it, you can put down the new one. If not, you can put down luan plywood which is thin. Then the new tiles.
