I always thought that plasterboard had a load bearing capacity of 20kg/m2 but according to the tta its 32kg/m2?
The maximum weight of tiling which can be supported by a dry, well-adhered plaster background is 20kg/m2, generally equivalent to ceramic tiles with a thickness of 8mm or natural stone tiles with a thickness of 7mm. When fixing directly to unskimmed paper-faced plasterboard surfaces the maximum permissible weight is increased to 32 kg/m2. These weights include adhesive and grout.
Is this correct? (which i assume it is), was i wrong in thinking it was 20kg/m2 (which i assume i was), or am i reading this wrong?
