Damp Proofing

Damp walls upstairs

Anonymous user 03/03/2024 - 3.26 PM

I live in a 1940's semi. The external walls in my house have damp problems on the inside ( if that makes sense ). Last year I cleaned all the damp and mould off using bleach and water, and mould cleaner. It has been fine through the spring and summer months. Now that winter is back the mould and the white salty stuff is starting to come back. I want to decorate he rooms affected by this, am I better to remove the plaster back to brick and put some sort of treatment on the walls and then re plaster? What is the best way of solving this problem? Cheers

The first thing which needs to be done is to remove the source of the penetrating damp i.e fill any cracks or replace the external render. The second thing to do is remove all salt contaminated plaster and replace with new sand and cement scratch coat with a waterproofer and salt inhibitor additive. Either plaster or dry line the wall.

with the information you have supplied it is more likely to be coming in through from the outside wall either the pointing requires doing or you have some porous or blown bricks. you need to find the problem before you can cure the internal damp.
