I have white 4 x 4 tiles as the kitchen backsplash. My question is can I just put peel and stick glass mosiac tile that I saw at menards over the existing tile. The tiles that I saw at the store are in 12 x12 sheets that have 1 x1 tiles in the 12 x12 sheet. There is nothing wrong with the backsplash except that it is very ugly.
Thanks for any infp

Make sure the old tile is very clean. You will still need to grout the new tile and caulk it at the base. If.you have any outlets in the tile fields you may need to get outlet box extenders . Do you have a tile saw?

Peel & Stick mosaics? Yikes. Are you sure you didn't see the Bondera stuff that sticks to the wall and then you stick the tiles to it?

I don't think much of either method BTW. Heat or sudden change in humidity and it might come down.
