I am tiling a shower tray and bathroom . The tiles that are selected are a porcelain tile. Areas to be tiled are an existing concrete block wall and an area I have relined with the waterproofed plaster board recommended for shower areas. What tile adhesive should I use since I am concerned with adherence utilising porcelain tiles , the possibility of non absorbtion surfaces etc.
What is the best way to drill a porcelain tile - I have tried a sample and seem to have little effect except if I use a hammer action. Drill wear is also an issue . Cutting via a diamond wheel is ok.
