Recently I laid some tiles (12x12) in my kitchen on a plain concrete surface, these were supposed to be self sticking but of late some of them are beginning to separate from the concrete. Any tips? Did I do something wrong? Should I have put down a mastic before laying the tiles? any comments appreciated. I thought they would stick to the concrete as I had previously laid some in the Bath room on a tiled surface and had no problems.
