It's been years since I have had to paint new plaster. I can't find any paperwork or notes on any job in the past that I have had to prime and paint new plaster. So, my question is this:
What would you recommend as a primer for new plaster? By new I mean it is a new plaster skimcoat, but has dried/cured for over 9 months. My first instinct would be an acrylic primer like BM FreshStart.
Any numbers as to material usage? I know it will be more porous than drywall, but how much? 50%? 100%? Anyone with a typical sq ft of coverage for new plaster?
Any help would be appreciated.
