hi (from troweladdicts better half)
just wondering if you could offer any advice re the following....
we live in a block of flats. some flat owners have problems with black mould/damp patches on the inside of some of their external walls. they open windows daily but still have the problem so guessing that this isn't caused by lack of ventillation/condensation.
what do you recommend to solve the problem? someone suggested painting the external walls with some solution to waterproof the wall. someone else has suggested injecting damp proofing material into the wall cavities - any advice would be appreciated!!!!!
