Hi there everyone. Hopefully I'm posting in the right place, apologies if not. We recently had the majority of our house re-skimmed and are very pleased with the finish. However, in our porch, there is one spot about half a metre long and 5 inches high going up from the floor that still hasn't dried out. It's been about 16 days since he finished it now. The porch has dried out just fine, apart from this spot. What worries me is when I took the old skirting board off in this area before our plasterer did the job it was pretty rotten, so I'm worried there's a damp problem in the wall. Our plasterer had some filling in to do before skimming and he used sand and cement on the interior of the wall in question. There seems to be some salt forming just above the wet patch too. Should I just wait it out to let it dry or should I call him to take a look? Thanks in advance.
