cant find a forum for paint but my guess is plaster is my problem so...
just moved in, whoever painted did a bodge job and so whenever i lean against an internal wall it leaves powder on my clothes.
so did they use the wrong paint or not under coat or prime? im no expert but want to paint over this and do away with the powder residue, can i wash it down with soap and water or need to strip, sand or what ?
please advise
