Ive got a job on monday plastering over artex and re-skimming all the walls. Theyve asked how long it has to wait till they can paint it as its there living room and obviously want to get it completed. I was told 3 weeks by someone but didint think multi would take that long to go off. Its only multi on the artex aswell as the artex was done badly and it only a couple mil thick. Any advice would be appreciated
