Hello,
Heavy rain in late 2013, coupled with soakaway failure resulted in a section of my home wall becoming very very wet. About 3m^2 of interior wall has suffered some "efflorescence" (salts lifting the paint) but the plaster is fundamentally in very good shape.
Drainage/soakaway is now fixed. External wall is thoroughly (waterproof) rendered and tanked to the footings and I am confident the it is as dry as it's going to be.
Now time to make good the interior.
Clearly the "belt and braces" approach will be to hack back and replace the affected interior plaster with a suitable system.
But I have discovered so-called "salt neutraliser" like
Any opinions out there?
