I have a huge problem all the paint that has been put on my stair posts and skirtings is peeling off in sheets, I think last time i did it I used crown satin one coat, I don't know what this guy has used but i did stipulate crown or dulux ( I think he used leyland out of a big tub as he kept going out to his van to fill his pot up) I also noticed a tin of dulux eco undercoat, is it all going to fall off?
