Hi guys. Been out of the tiling game for some years and just about to tile kitchen and hall in 60*60 porcelain. Tiling over a chipboard floor and laying 6mm hardibacker first.
My question is, is it essential to need the hardibacker onto adhesive then screw down or can you just screw the boards straight onto the chipboard? If bedding the boards onto adhesive first, what size trowel? Tia
