Hi I am painting an old plaster wall in an older home. I have noticed

Product) still be beneficial for the moisture problem????
Thanks

Calcimine would dissolve when wet, so doubtful that is what is peeling. *
You NOTICED it
was painted 8 mos ago, or you painted it 8 mos ago? *If you have a
moisture problem,
you need to fix it before you paint again........no primer is going to
stick to a wet surface
and not blister or peel. *Is it a bath or kitchen? *If conditions were
damp when it was
painted, and there is no leak, then the solution is to get the space
nice and dry and then
use a primer and paint labelled for use on plaster.

hi there. It was painted 8 months ago by another painter. Now it has
peeled right down to the plaster. This is a bedroom, brick house...The
plaster is dry not wet..and when it was painted the walls were totally
dry no moisture.
