Best Primer For Bare Pine And/or Raw Drywall?

send_it_all

What is the best primer to use on raw pine and raw drywall?...If it is oil based, is there a good water based alternative? I want to use an airless and would rather not spray oil if I can avoid it. If I can't it's not the end of the world. I searched and surprisingly got no matches to my thread title.

It depends

If the pine is knotty, yeah you'll need oil for that
If it's clear, then latex would be OK

Personally I like Pittsburgh's Speed Hide Primer/Sealer for new drywall
Ben Moore's Fresh Start for pine (oil or latex depending)

Thanks Slick. I,ve been told I should use a seperate hose for my airless for oil based products. Do you agree with this, or do I just need to flush mine out properly?

Somebody here mentioned putting a waterproof glue like Titebond II on knots to prevent bleed through. I haven't had a chance to try it yet but it sounds like a solid idea. Lately I've switched to BM's Fresh Start Penetrating Primer, it's a sure cure for cedar bleed.

I love this site....It makes everyone better at their job...Thanks everyone.

still could use advice about the airless hose. Oil and water through same hose...or buy a seperate one?

painterofeveryt

same hose,just flush it well ,very well (this is not lacquer so its not going to loosen all the crap in your line.

Yes...2 hoses is best. Why take a chance (which could turn into a very expensive one) if you can avoid problems with simply having 2 separate hoses?

As far as the primer:

Oil based if it is a wood that bleeds, typcially harder woods-SW Problock Oil based (they make an odorless as well...it still smells a bit)

Latex for pine - I use SW preprite problock

Zinsser BIN for knots-2 to 3 coats

Bah... I don't really like swapping back and forth my machines from oil to water just due to the expense of cleaning them, however... haven't had a problem doing so in 30+ years.

Agree with the really knotty oil, flat sheetrock? I prime with the cheapest there is then sand all the hairs.. go from there.... if it's textured I sorta like BM's undercoat.
