    hi all
    can anyone solve a problem for me I've recently tiled some new bathrooms only to discover 3 months later they've started to Dr bond off the walls
    it was new plaster and I primed the walls with sbr and used powdered flexible adhesive so it's left me at a loss to what I've done wrong
    any advice would be most welcome

    2 weeks I'm kind of thinking it was wet plaster as it was in the middle of the really cold spell this winter

    Was it a float and set or skim coat. Float and set needs much longer than two weeks.

    it was 2 coat plaster and like I said earlier in the middle of the really cold spell so it looks like it was tiled too early

    Why did you tile on to paint?

    Also, you say 2 skim coat. You’re talking about a standard skim up in two stages with no Bonding or Hardwall involved?
