Hi, i'm sure this as been asked many times but i cannot find the answer through various posts. I am going to re-tile my bathroom with 30 x 60cm porcelain tiles. My bathroom is mainly studded walls and to take off the existing tiles i will cause too much damage to the walls so i wanted to tile over them. What is the best adhesive to use as they are big tiles and whats the best method to prep the walls prior to tiling?
Thanks
