OSB still bleeding through........

[tlmartin84]

Okay fellas, after reading all the posts on here I could find, I decided to go with OSB for the interior walls, followed by a high solids primer.

I decided against Kilz oil based due to the fumes and mess, I don't mind some bubbles from the OSB lifting so far I have 2-coats of Zinsser 1-2-3 Acrylic primer.

The OSB is still having spots with some yellow popping through.....I am assuming it is the glue or something.

Anyhow, is it normal to still have the yellowing after 2 coats?

I was planning on 3 coats of the ZINSSER with no paint......

Will the third coat of primer get it? or do I need a couple more coats of latex paint?

Did you guys still have some yellowing after the second coat of Kilz? or was it completely white?

BTW I want the walls WHITE!

Everything I've read always said to use oil based for this.

 

[UpstateNY]

I used oil-based on my OSB, 2 coats, worked great.

DITTO on what UpstateNY and Robin said.

 

[tlmartin84]

Upstate, oil based as in Kilz original?

Did you top coat it?

No bleed through at all after the second coat?

 

[The Cobbler]

latex paint does not have a good bleed resistance. oil base for a primer then top coat

Yes, top coat it. When I did my garage, I thought it would be fine with just two coats of Kilz oil based primer. My ignorance with the product showed later when it slowly yellowed and I had to paint it all again. I top coated with Kilz Pro-X 170 latex.

The house garage got two coats but I top coated it with some Behr exterior latex as it's an unheated space. I felt the extra cost (couple bucks a gallon) was worth it instead of using an interior latex paint. It still looks good.

Here are some pictures after the 2 coats of Zinsser.

Primer is not great at hiding what is under it and it won't give you the solid and bright look that you want. It is made to stick and cover stains in prep for the finish.

Pick a decent (mid grade, acrylic/latex) paint to top coat it. If you use ultra pure white, it will be very bright but it will take two coats to cover the primer, one coat if you get lucky and are not really picky. You can spray it on, but I would at least back roll it to work it into the texture and even it out. Make sure you use plenty of product as most people roll too dry.

As far as the yellow, it may or may not show back up. The zinsser primer is great and it should have sealed the surface quite well. I would apply some of your finish/paint and see if the yellow bleeds. Just do a test area. If it bleeds, use cover stain oil based primer or BIN primer, from zinsser, then finish it with paint. The cover stain works great and would be my first choice. BIN should be thinned and cleaned with alcohol. It is good for smoke and fire damage. It also isn't an exterior primer, other than spot priming. It is good for very bad stains.

With the primer already on the osb, it shouldn't be hard to add a coat of oil cover stain, if needed. If it was bare osb, it would **** the primer up even more.

I don't recommend kilz anything.

Oil based paint will yellow when it doesn't get sunlight, and it can yellow when it does, but at a different rate. You can see the outline of picture and other items on a wall painted with oil based paint.

X2 on not leaving just the primer for the final coat.

Zinsser makes multiple kinds of primer. Cal the company and ask which is best for blocking this type of bleed through.

 

[walrus]

I did 2 coats of kliz oil based primer and then 2 coats of Behr Latex semi gloss white. It was white

 

[bigarmzz]

i used 2 coats of Kilz oil based primer/paint and you can still see those pesky "little yellowish spots"......lesson I learned from this? i'll never paint osb again, was a huge PIA!!

next time, i'll just cover it up with paneling and say screw it

Thanks, this was the answer I was looking for. Sounds like there isn't much difference between the water based ZINSSER and Kilz Oil Based then..........

These OSB wall covering threads remind me of this...

Curious what Kilz product you used for the primer, and what paint you used?

 

[theoldwizard1]

Expensive and requires alcohol for clean up but by far the best stain blocking primer.

Zinsser Shellac-Based White Interior/Spot Exterior Primer and Sealer

 

[Maddog10]

Two coats of Kilz oil-based primer got my walls a consistent white, but adding a coat of paint over the top gave the ultra-white appearance you are wanting. No matter how many coats of primer you put on, you still want to paint it if you are wanting the brightest appearance.

 

[k-os]

I used 2 coats of the regular Kilz Oil Based (after sanding the walls with 120). Then I used 2 coats of exterior latex white over it and don't have any bleed through.

Zinsser Shellac-Based White Interior/Spot Exterior Primer and Sealer

Oil primer (Kilz or Zinsser) or BIN Shellac. The advantage of the Shellac is that it dries super fast, like in 15 minutes. It is very thin and easy to spray. It has a strong alcohol odor, but goes away really fast. It is widely used in fire/smoke restoration. The disadvantage is cost.

At this point, I would spot prime the bleeding areas and topcoat and move on...

Good luck

Yeah, if people are covering with primer and then expecting to not paint... get real. Primer has like 1/10th the amount of pigment/solids as a quality paint. It's meant to do the surface prep, you will still see a LOT show through. But the finished product should be able to accept paint without issue.

If you're unable to get to that point, there's something wrong like oil on the OSB, or something else that shouldn't be there.

I used this primer (1 coat)








And this paint (2 coats)

Sorry if the pictures are screwy, I'm having trouble with tapatalk uploading pictures.

I did coats of kilz oil primer before I installed it on the ceiling. Then one coat of oil base white paint also before I installed it. After installing it on the ceiling a little touch-up on the seams an screws. Nothing coming through and the look is fantastic. Couldn't be happier.

Depends on the primer, most of these stain sealers are close to 50% or more solids, which is far more than your typical paint.

Was just going to suggest Problock. Best oil primer imo.

That stuff ain't no joke. You need to wear a good respirator when using it!

 

[tlmartin84]

UPDATE:

Just so anyone else who is going to do this knows........ I applied 2-1/2 coats of the Zinsser 1-2-3. And 1 coat of a Maintenance Grade Latex Semi-Gloss and I am now bleed free.

The "1/2" coat was a thinned down (by water) version of the primer, and it was leftover so I thinned it to be able to coat everything a final time. I still intend to follow up with a final coat of semi-gloss.

I am now confident that 2 coats of the water based Zinsser and 2 coats of Semi-Gloss will in fact yield the same results as using the oil-based products. Note that I still had a few chips pop, but that isn't an issue for me.

 

[CGT80]

That is great news! It always ***** when stains show through primer, but you don't know if it is just the color that shows or if it will actually bleed through the top coat. If you do get bleeding down the road, update this thread so others can see your experience. It is possible for it to take a while to bleed, but hopefully that won't happen with how well you primed and painted the surface.

I'm glad you posted the results, because those threads where the other person got right to where you are and then didn't post anymore about where they ended up are quite frustrating.

 

[UpstateNY]

Upstate, oil based as in Kilz original?

Did you top coat it?

No bleed through at all after the second coat?

Yes, Kilz Original - 2 coats, then top coat with 2 coats of Behr latex premium semi-gloss in a light yellow color. No bleed through.

Thanks, good to know.

Just a thought, with OSB in a garage I would think about a fire blocking primer. There are borate based ones, and something called intumescent paint.

Yikes. But then again I do a lot of grinding and welding.

I did my OSB walls with 2 coats of Killz Oil primer and topcoat of latex paint. Looks awesome!
