Problems with condensation and damp around the house

Damp in brick walls and plaster

Postby Mal » Tue Sep 30, 2008 4:26 pm

I live in a terrace house from the 1920s and have had a damp problem in the top corners of the two front rooms upstairs. Although the walls are wallpapered the plaster is obviously loose behind and the wallpaper itself mouldy.

I am assuming the problem is the gutters leaking as there are joints at each side of the house, but if I fix that can I immediately replaster, or do I need to wait until it 'dries' or does the new plaster need some treatment in it etc?

The damp loose plaster is a symptom of the fault - fix the fault and then let the wall dry out for at least 2 months before replastering - it is the bricks than need to dry before you put more plaster on!
