I used these in my Mom’s kitchen and 2 small bathrooms. The tile in both bathrooms has stuck and looks great, but in the kitchen it keeps coming unstuck from the walls around the stove every time she uses the oven. I washed the walls, first with a soap and water mix, then with alcohol, then we painted the walls with 2 coats of paint before applying the tiles. At this point some of the tile panels look like they have slipped down the wall and the seams don’t match up. I don’t know what to do to try to get them to adhere better, but given how they have moved down the wall if may mean I’ll have to remove and replace all the tiles in that section of the kitchen. All that is to say that it seems great as a backsplash for a bathroom sink area but maybe not for the kitchen around the stove.
