hmmm, which to use on a painted wall prior to skimming...!!???
should i pva the painted wall (1:5) a couple of times then skim when tacky, or should i use wickes bonding agent?
OR, to be extra sure, should i pva the wall to seal it (cos there are some crumbly bits) THEN use wickes bonding agent, let it dry, then pva (1:1) for adhesion and skim when tacky!!? or is that OTT??
what do you think?
Cheers!
