I painted Dulux Supermatt onto dry plaster without watering it down (stupidly not reading the instructions I just used it like I usually use paint). I now realise - too late - that I should have watered it down (just from actually reading the instructions). I did the first coat yesterday and have just done the second. There don't seem to be any problems so far, but I'm wondering if anyone knows how long it should be before I either see any peeling (as I've read can happen) or can be fairly confident I've got away with it (is it possible to get away with it??)? I was planning to paint over the walls with some other paint and tile some areas (it's the kitchen) and leave the ceiling as is. Any thoughts or suggestions on how to proceed would be much appreciated!!
