Perfect Tiling
Hi guys.....been asked to do a very large set of outdoor steps that form the main entrance to a very nice house...however...there is a problem. The tiles are coming loose after another tiler refixed them two years ago after they came loose then. Behind the tiles seems to be a layer of possibly limescale coming from the substrate and pushing the tiles off. The substrate is poured concrete with a smooth render which has been down for about 10 years or so. Is there any way of stopping this limescale from coming through the steps. I dont want to go and tile the job for the same thing to happen in a couple of years time. Cheers in advance.
