PVA or mist coat on plasterboard skim

[Heatslave]

Hi ,

The search function didn't really help, so can the pro's please let me know if I should pva or mist coat a brand new plasterboarded and skimmed ceiling and stud wall before painting properly ?? The reason I ask is I don't want any flaking paint in a year or two's time.

Many thanks

No.
Gardz or Beeline sealer

The correct answer is mist coat. Never PVA before painting, as it stops the paint from adhering properly. PVA would be used to sonsolidate a surface before plastering

Mist coat and give the surface a quick once-over with some sandpaper first.
