problem with new plaster - TilersForums.com

[paddy]

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

How long was the plaster left to dry ?

 

[paddy]

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

1 or 2 coat plaster?

Is the plaster coming off the wall as well?

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

Should of been left for at least 6/7 weeks longer if no heating......or I would of used a dehumidifier...

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
