A small area (about a quarter bag) was skimmed (2 coats onto board) - 3 days ago, the finish isn't great, bit bumpy etc, not bad for his first attempt.
I'd like to re skim it, but have a feeling the existing plaster (not painted) will suck the water out of the new plaster instantly.
Whats the best way ? pva and skim? key it? if pva, which % and how many coats?
Many thanks
