Painting OBS

[Summer219]

I painted my osb porch ceiling with 2 coats of oil based primer and 2 coats of oil based paint and there's bleed through. How do I stop that? It looked great until it got hot.

Usually, Shellac it 1st or use a sealer

Looks like this thread was a victim of site restore, but as was mentioned a few times, best thing is to get some nicer finished grade wood and install and paint that. OSB will never look good.

I just use ceiling white paint and the walls look like stucco. No bleed through.

The location may have something to do with the bleed-through, possibly moisture related. I used 1/4" OSB on my shop walls and painted with one coat of primer and one coat of finish paint. Other than dust it has held up well.
