Hello!
can anyone help me with salty, flaky interior walls: some of our walls are fluffing up and paint is crumbling off due to salt residue, caused by I think damp penetration/builders using old plaster. I read down some of the topics on this website and think I may need to get hold of some Renderproof Water proofer. Where can I source this? What is this made of?
Many thanks.
