I have a damp patch one meter diameter from a leak through a party wall (from pipes in the floor of a flat one up and one across) The damp starts about 6inch below ceiling level. My patch is repeated in the adjacient flat.
The plaster is one coat, dark grey half inch thick onto red brick, then painted. It seems to be soft on a trial area. Will it ever be okay to dry out, clean up and over paint, or should it be hacked off and replastered for a lasting job?

I suspect it should be hacked??

Hi

Have you had a look at the diy projects area, especiallly the project on repairing plater: https://www.diydoctor.org.uk/projects/dampplaster.htm

This may assist you.

If the leak has been fixed it should dry out but if the wall is damp right through it could take a long time. Basically takes I" wall I month to dry out - so a 10" wall takes up to 10 months!

If it is damage plaster you might as well hack off and repair bu dont use bonding coats or light weight plasters as these will just absorb the moisture from the wall.

Gerald Diamond,
Let the wall dry out and then test the plaster again.
