Default PVA primer

I used a pva primer on a previously painted bathroom ceiling and walls. I did not paint over the primer yet. I am told that PVA should not have been used in prep of painting. Will the PVA affect the painting in the bathroom (peeling, flaking etc) or will it be ok.

If this was the wrong choice, how can i fix the problem

PVA is really more of a drywall primer/sealer best for unpainted drywall. If you just used it as a primer on a previously painted surface it probably was not the best choice, unless you were spot priming some drywall mud.

For a bath room I would be looking for a better stain blocker, are you a professional?

Yes, stop going to the Home Depot paint desk and hire a pro.

Depending on your reason for priming there might not even be a problem, if you are unsure or simply really worried about it I would sand the pva rather generously and reprime with either a oil based primer/stain blocker or Bullseye 123 waterbased stainblocker primer.

Of course you never said what your reasons for priming are but in the bathroom you often can run into stubborn stains.

What type of apprenticeship program? State run? Private? How long is the program before Journeyman is achieved?

Default pva primer

the program is through a private company and the local union.
i recently started there.

the primer was used since the ceiling was just textured. while using it on the ceiling we used it on the walls as well.

If you were not trying to cover up a stains on the walls you may be alright, again in the future I would select another primer but I do use PVA for new drywall.

How long is the whole program? You should be able to slide into a good union job from it.

For the ceiling it is fine, sounds like you will probably be fine on the walls as well.

Someone else will probably jump in and concur and another may jump in to say PVA sucks lol.

Nope, all PVA's that I know of are sealers as well.

I wouldn't sweat it.

But to be on the safe side you could perform an adhesion test on the walls. Score an 'x' in the primer then apply some packing tape over the top of it. Pull it off. If the paint remains on the wall you're golden. Otherwise sand it off or bury it under more primer and paint. Or tear out all the rock and start over.

It's just primer. Yer fine.

u primed over very dirty, oily, stained stuff, glossy stuff. even then, just test for bleed through, adhesion. Reprime if you see problems.

To be honest, I do not think the paint store I go to even carries a PVA primer nor have I ever used on to my knowledge.

Is PVA just an old school thing?

it's just a cheap, thin primer mostly used on bare drywall...I believe it is clay based

I have always used either BM 253 or 260 (vapor barrier) or PPG 6-2 on drywall.

No, it is just a drywall sealer, mostly used in NC because it is used to seal new drywall. Not the kind of primer you use for wood work or anything like that.
