Traditional ceramic tiles are installed by embedding them in wet mortar. This is because they are too heavy to be supported by adhesives alone.
Peel and stick backsplash tiles are specially designed to be thin and lightweight, and are made using synthetic materials that are strong but not heavy. As a result, these tiles can easily be installed using powerful adhesives on a smooth surface.
These tiles already come with pre-applied adhesives protected by a removable backing paper, so installing them is super easy.
