Vapor Barrier primer??
Have just been contacted by my client's builder. He's asking for a vapor barrier primer (plaster walls). I have no experience with a vapor barrier primer.
I have always been a fan of Zinsser products but would prefer to use a primer from the same mfr as the finish coat so that we have no warranty issues down the road.
Color specs are Ben Moore, but I am willing to shift or manage the matching if someone else (PPG or S-W) has a better primer product.
Thanks in advance for any wisdom or advice...or both!
