Bathrooms And Primer

lornmastro

Need to paint some new bathrooms. I was planning on using an oil primer because it is impervious to water and then 2 coats permawhite. Do you think I can use a quick dry oil primer...or should I stick with the the slow dry?? Thanks

Quickdry on gyp will work fine. Even a sealer like kills will do the trick.

On wood, I stiill like an oil primer on all wood but that is me, I'm old. Some of the new waterborn enamel undercoaters appear to do a good job of priming but maybe in a bathroom it might be best to prime with oilbase on wood.

I have a can of Perma-White sitting on a shelf above the computer, says 'No Priming Required!' right on the can.

Perhaps I didn't understand the question.

I use CoverStain oil for
bathrooms all the time.
I think it's really great with
DenseArmor cause I can build
a nice texture to hide the
joints against the fiberglass
mat.

I use Kilz oil in rental bathrooms all the time no problem.

Thanks all for the reply. F.Y.I. I have been told about failures with permawhite used as a primer...I'll play it safe and prime first.

I am not a painter so pardon my ignorance; I have had failure when painting over unprimed hot mud, and will never again paint unprimed drywall. But someone help me out here, what makes oil primer better than water based in a bathroom?

Better moisture resistance.

New drywall should be primed with drywall primer.
Oil anything is not a good idea in bathrooms,
as it is food for mold.
Coverstain and Kilz oil? In a bathroom? Save your lungs.

That is tru about mold feeding on oils so I would leave them out. Another thing to consider is if the color is super dark or if there is a lot of tine because most latex materials, no matter who makes it are capable of rewetting and actually streaking. if it is a light color it is not as prone to do it but jsut a lesson learned situation there. I would look at the prema-white line or SW bathpaint is also a great product and is self priming. I also prime everything even under these situations however.

You guys have a source
for that info?

Because oil base makes
a damn good vapor barrier.
Water born generally doesn't.

George has a hard-on for low/no VOC.

I'm thinking maybe it's because he don't wanna have to invest in respirators for his crew.

Coverstain rulz..and I'll quit using it when they pry the (rapidly drying) China bristle brush out of my cold, dead hand.
