Hi guys,
I have just had a new conservatory bulit. It has a dwarf wall, 3.5 square. I am really pleased with the finish but just noticed a day or so ago an area about 200mm by20mm on the reveal leading upto the french doors. It is a kindo of white powdery residue coming through the paintwork. I dont think it can be damp as the guy had good founds down and it had a good DP membrain. Once it was boarded, dot and dabbed and skimmed i let it dry naturally for about a week before applying a good coat of PVA (5-1) as it said on the container. I then gave it a further couple of days before applying 2 coats of good quality scrubable emulsion.
Any ideas please??
cheers
