Hi there,
I posted a while ago prior to carrying out prep work for tiling a new bathroom with Travertine. I followed the recommendation and adhered backerboard over the plastered walls using weber SPF rapid and mechanical fixings but would like some further advice on the floor.
At present the floor has 18mm WBF plywood screwed down onto 8 x 2 joist with extra noggins fitted to ensure all sides are supported. It is pretty rigid and you need to jump up and down in the middle of the room (3.2m x 2.4m) to get a glass of water to ripple. Initially i was going to adhere backerboard over the ply, again using wbere SPF rapid but having checked the floor level and there are a few high points and also a gradual fall diagnally across the room (about 15-20mm between highest corner and lowest corner). Obviously the builder didn't have a very good level on this extention build.
As i'm now fitting 600 x 600 polished porcelein tiles on the floor (again with Weber SPF rapid) i'm a little worried about getting them level and also how much adhesive would be required to ensure the floor is level over the high points and also with the fall. Would it be best to either put down some flexible SLC over the plywood or alternative fit the backerboard and then put down Flex SLC. This would give a good level substrate to tile onto.
Also i've now decided to fit 600 x 300 travertine wall tiles on the backer-board instead of the original plan of 400 x 300. I have already gone out and purchased Weber.Set plus so wanted to know if this adhesive will still be suitable for the bigger sized tiles or do i need to add AD250 to it?
Many thanks
Ben
