Unhappy Peeling primer from new plaster

Ok. I know I screwed up, but now I have to try to fix the problem... After having a professional plasterer blue board and plaster a new room in my home, I hand sanded, then damp wiped the new walls prior to priming with a Behr primer designed for new walls.

Wouldn't you know, within a week I saw what looked like bubbling and when I attacked it by hand, the primer came off in sheets as big as 4" x 10" and as small as finger nail size. And, of course, not all of it came off! The problem doesn't seem to be the walls, three of them are new, and one is the old, lath and plaster. The problem is the ceiling.

So, now the question, other than pole sanding or hand sanding, do I have any alternatives to get the primer off or smooth to the point where I can re-prime and paint?

Thanks in advance for you help!!!

I'm lost

Welcome to the forum.

I am so confused. The problem you have is confined to the primer peeling off of the ceiling, right? And the ceiling is brand, new plaster?

You're right on the money....

Yes. I don't think I did a thorough enough job cleaning the dust off the ceiling before priming. That's why the primer peeled off in a lot of places, but adhered well in others.
Hope this clarifies things a bit.

Thanks.

I fought an extensive paint failure on the plaster walls in my 60+ year old house.

Take a scraper and scrape off what will come off. Clean the rest to get the dust. Prime with Zinsser 123 to bind the whole shooting match to the ceiling.

Now you could skim some joint compound to feather the edges of any remaining transitions or simply sand the transitions to feather them, then re-prime. Ceiling are pretty forgiving in that almost no one can take much of a look at them.

If you are going to sand just the primer over the surface, let it set for 2 -3 days. Zinsser hardens greatly over a week, making sanding easier.

Zinsser did wonders for the problematic, peeling walls I have.

Hope this helps.

for starters,just curious as to why you had dust on the ceilings and walls,plaster is not to be sanded.it should be as smooth as a babies butt when applied by a good plasterer.even if the plaster work was sub par don't sand it,prime first then mud in areas that are eye popping or uneven then sand .having said that i have seen primer not bubble or pull away from dust but only fail such as when blue tape was applied then pulled off or if sanding was so that it was sanded through the primer to bare wall then the easy pulling off of primer was present from the dust being on it like flouring a pan before baking.being that you say it is only the ceiling ,my question is what is above the ceiling.are there water lines running above it and are they in the attic, cold lines will sweat in a hot area,a bathroom,an outside patio,a flat roof or a roof that needs redone.moisture may be the problem .check this first and do what you can to remedy it , if not the problem will never go away and the paint will do the same thing as the primer.second did you wait the 30 day cure time for the plaster before priming and was the primer specified for plaster.when plaster cures the chemical reaction creates an unstable PH level for normal primers and paints.for future reference there are alkly (close to spelling pronounced ale-ka- lie)resistent primers made for concrete type surfaces such as plaster and morter.can be used prior to 30 day cure and in my opinion should be used on these areas regardless.another question is the plaster bubbling too or just the primer?

Reelski,
Sorry to say, it was recommended by a GC friend that I lightly sand with mesh screens, using a pole sander. The ceiling did look smooth as a baby's behind, but I took his advice. I was also doing alot of trim work in the hall outside of this room, (a week or more after the plaster job, and know I kicked up dust from the saw, etc.
To answer your other questions, I waited more than a month before touching the ceiling, and while the ceiling backs to my attic, there are no pipes running overhead and before the plaster job, I put R-30 between the attic floor joists, so I know it's not a temp/moisture issue. Also, it's just the primer, not the plaster that's peeling/bubbling.
With a brand spanking new ceiling, dust is the only thing that I can guess it was, when considering that the primer came up in sheets in some areas and not at all in others. The strange thing is that two of my walls are brand new plaster and they didn't peel at all, So I'm thinking that it couldn't be the primer...

Guess I'll go with sanding out the edges of the primer to blend it in and then clean and prime again.

Thanks again everyone for the welcome and the advice.

A light sanding on existing surfaces is a good idea. The dust will stick to anything though, even the ceiling, so you should always vacuum then wipe the surfaces with a damp rag or tack cloth.

Primer peeling

I have the same problem but the primer is peeling off all the walls in the entire BRAND new home. Builder is running and the attorney bills are mounting to fight what was done wrong in beginning.
Any suggestions?

Hi Maura,

Welcome to the forums. It's best to start a new thread when you have a question, rather than ask a question in the form of a reply...especially on a very old thread.

Having said that, the answer is pretty much the same- sand, prime with a binding primer then paint.

What type of walls do you have? plaster veneer or regular drywall? What did they look like prior to priming? Was the sanding dust removed?

What brand of primer are you using? Are you doing the painting? or the builder? paint contractor?

Any suggestions?
There could be many reasons why this is happening
It's hard to say w/o a further inspection
It could be they didn't wipe off the sanding dust before spraying
Could be they sent some monkey with a spray gun in there
Could be....

Do you want suggestions on how to DIY fix it?
Or what could be the problem?
