Hi guys had a little thread going in the Tilers forum asking for a it of advice on tanking the former with Kerdi, but Im happy that has now been solved. Got a it of another issue/query my bathroom is roughly 2.5m x 2m in an old 1906 tenement flat my joists are running along the longer wall of the room an are roughly at 400mm centres.
The issue I'm having is they are all un level from each other, because of this I decided to put down 25 wbp ply and pack under the ply until it was level. I've done this and now have the ply level in each direction and am happy with that. But when I sit my former on the ply is seems to sit flat on the outside edges but the centre isn't lying flat on the ply it's as if it's sprung up or the board has a twist or something in it? I was thinking about glue it down and using some weights to hold it down?
Any ideas?
