All About Primer

[crokett]

The OSB that is on my shop walls inside is going to suck up paint/primer like a big 'ol slurpee. So, was killing time at HD today and they have Olympic interior drywall primer for about 80 bucks for 5 gallons and another interior PVA primer for half that. I got curious what the difference was and which one was best and decided to do some research. I found this writeup which is pretty good:

Translation for me is I won't buy the higher-cost drywall primer again, even for drywall but will stick with the PVA, at least for walls.

I use 2 products for priming. Gripper or Kilz. Kilz is easier to work with and Gripper sticks to anything & is harder to cleanup. Normal drywall job = Kilz. Smooth items like pegboard or hardboard = Gripper.

what, a primer on primer?

[crokett]

Mike, I stil use killz and will for stuff that needs to be sealed, hidden, but it costs 13 bucks a gallon. The PVA primer I looked at is half that.

[Hellrazor]

Don't look at Gripper... $20/gal or $92/5gal

BUT.. if you need paint to hold to a very smooth surface, it rules.

If you have an air compressor already in place...try this. First, seal all the osb
surfaces with spray shellac...it really seals the surface well and makes painting
a whole lot easier too! The paint won't be absorbed into the surface either, I have been using this method lately and wished I had discovered/ tried it years ago.

Primers

I once had a rental property. The tenant was there for 18 years. He smoked heavily and never put a drop of paint on the ceiling or walls. When he finally moved out, the living room ceiling was almost brown from smoke. I used 3 coats of Kilz, but the smoke kept showing thru. A contractor friend told me to use Zinzer Bullseye Primer. That did the trick. I have been a fan of it ever since. Not sure if the first 3 coats helped, but I never bought it again and never had a problem with Zinzer. So in my opinion, it is the better of the two.

Thanks,

Paint & Primer

While we are on the subject of primer, I am going to paint my house next spring. HD has a combo house paint and primer. Has anyone used this? It sounds like a good way to go if this is any good. I plan on two coats.

Thanks.

Is that the Zinzer primer that is made from bug juice? Or is that shellac? I prefer the Zinzer for priming stained surfaces. But you still have to sand it.
And oh yea, the primer is in the paint theory. If it takes 2 coats anyway, which mine almost always does, are you not putting on 2 coats of paint that is too expensive to begin with?

real shellac is bug juice. Is there a different bug juice coating?
