Lads can anyone help me out here , I'm on a job and the lady in the house is sayin my grout joints are too wide , the tile is a porcelain wood effect , 900 x 25 and the grout joint I used is 2mm , it's on the walls and floor , the tile does have a slight bevel on the back which does make the grout joint a little wider , but I've told her 2mm is the minimum to allow for movement , many thanks
