I am using STAINMASTER Charlotte 1-piece 9-in x 9-in Groutable Black and White Peel and Stick Vinyl Tiles to cover a backsplash in my kitchen. I notice they are not adhering to the glass tile backsplash too easily. I read online with the peel & stick tiles, I could not use an extra adhesive product. I cleaned the tile really good before applying the tiles also. I am now applying one tile a day peeling off backing then use a hair dryer to heat the back of tile sticky part then apply to wall. It sticks! Then I use a filled water bottle & place it against tile so it does not fall off wall. My question is: Is there another way? I was thinking of NOT peeling the back of tile, keeping paper intact, then using an adhesive product. Do yo think that is a better solution? Any suggestions are welcome 🙂 Thank you!
