Hi,
I've just bought a 1900 terrace that has solid external walls and the surveyor told me there is damp from the external walls. He said the slate dpc may need replacing but he also said there may be penetrating damp and that the original internal plaster will need replacing soon. I have read a little about solid walls and there seems to be 2 main methods of dealing with this after I remove the original plaster. 1. to use lime plaster and let the walls breathe or 2. to seal and insulate the internal walls e.g. using polystyrene backed PB attached to wooden batons.
The outside of the house has been painted though. Would normal external paint allow the bricks to breathe and how do I know if the paint used was breathable? If it's not, should I go with option 2? I also have to repoint some of the bricks, should this be done with a lime cement? Any advice much appreciated and of course correct me if I've got completely confused
Thanks!
