I've go a ton of left over off-white ceiling paint. Can I use that as a primer for newly constructed drywall walls, or would that be, well, stupid? Or at the very least, a waste of time.

Generally speaking, ceiling paint does not work as a stain blocker. If you use it, you may see discoloring in your final color.

I had a water stain in my ceiling a few years ago from Hurricane Wilma and tried to cover it with ceiling paint. It just stained right through. I had to buy some Kilz to cover it up and then paint again with Ceiling paint.

Hope this helps.

An ordinary primer isn't going to be an effective stain blocker either. If you don't need a stain blocker, go ahead with the ceiling paint.

Note, ceiling paint is a rip off. The difference between it and wall paint is that they can get away with skimping on the titanium dioxide (TiO2) because ceilings are usually in good shape and don't good hiding power.

I dont think he asked about gettin ride of stains. can you use ceiling paint? This is what i think...... as long as it is flat. i will say yes. Ive done it myself and had no problem, i dont know of any primers that have a gloss of anykind to them. so to me with exception of stain blocking ceiling white and just regular primer will do the same........just my opinion

reccles

That's correct. Since I have all this ceiling paint, I'd rather use it up rather than going out and buying primer. The walls are new - no stains - just drywall, tape, and mud.

Thanks

Many professional painters around my area are using cheaper flat paint in general as a primer coat. It usually hides well and costs less than primer. But consider that any paint, including ceiling paint, that is used without a primer first over naked sheet rock has no real sticking properties. It's not all about hide, it's also about your very first coat adhering to the new wall material. Using up your ceiling paint is a good idea in theory but you may be sorry down the road when it doesn't hold up, or even begins to flake off. And don't even think about using any kind of tape on those walls, in case you should ever decide to stripes or any kind of decorative technique, as the paint will almost certainly lift off during tape removal.
Can you perhaps prime your new walls with primer and then use the ceiling paint as your top coat? If you mix it with other leftover paint, especially one with some sheen, you may create a pale color that has some durability.

This is what the last homeowner of my house did. I have certain walls that the paint literally peels off in sheets. Other walls in the house look fine and don't have this problem. If this is the case, yeah, use a primer when painting right on to sheetrock.

I've used flat white as new build primer and never had a problem with it. Saved money and got rid of the cans of paint that would have been thrown away.

That is good news but you have been lucky. Right now I am painting the interior of a large home, along with other painters. The walls were primed by the contractor using an extremely low grade primer, actual primer (or so we have been told). Those of us who are doing specialty finishes are using the lightest tack tape on the market. Without exception, all of us are having to do major touch-ups because after the tape is on for only 1 hour, upon removal everything comes off with the tape right down to the sheetrock. This is a classic indication of flat paint having been used instead of primer or a cheapo cheapo primer being used.

One might just get away with no problems, if doing a straight paint job. But one day down the road it could peel and flake off, or one day you might hire someone at $400/day to do something custom or artistic to your walls and that is when the consequences of using flat paint in place of primer will hit. Try striping a wall that has never been primed and the importance of primer will become aparant very quickly. Primer is manufactured and used for a reason. It has it's place.
