i painted directly onto new plaster which i now know was wrong, and it left a swirly pattern in the paint, i have spent days and days washing of the paint and now it is back to plaster but the plaster still has the pattern in it that was there when i painted it, i have bought some new plaster sealant but am concerned that if i paint it again the pattern will still be there, do you think i should get it replastered, help x
