February 28, 20251 yr Our new build has Caberboard 22mm fllor on the first floor. It is very flat and strong with zero bounce. I cannot see why i need anything under it before i tile it. Am i being an idiot or is this a simpe thing please?
February 28, 20251 yr Caberboard is water proof with a coating, I would be worried about the adhesive just lifting after a short while. So you may have to do something to act as medium to allow a sound connection. Maybe an overlay of ply or something similar? What do the caberboard instructions or website say on the subject?
