Hi maybe someone can advise/guess what's happening
new plasterwork, dried out etc, apply Jonstons "obliterating white" matt emulsion diluted 5:1 with water as per instructions.
applies fine to new plaster ceilings (scimmed plasterboard) and mos new plasterwork on walls.
however...
on some walls the paint doesn't cover evenly leaving patches which are then very visible - where is thin is very much lower than around patch where coverage is ok.
Since want to finish walls with emulsion (other than white or magnolia & probably not a matt type) need to remedy this, but no idea how.
(a) anyone any idea what is happening with the base/primer coat (b) how to fix the patches so they won't show up
baffled
