went to look at job today and customer has bought 12mm travertine tiles .Tiles are going about 1.2 m up wall but the wall is skim over plasterboard !!!! I understand this is isnt suitable for the weight of the tile and need to know next option to tackle this prob.Should i screw hardibacker to the wall first ? and how can i deal with the extra backing thickness ? as the tiles are only 1.2 m high the thickness on the top tile will be visible ..ta
