New paint bleed through.

Paul Rapoza asked 3 years ago

I used two coats of Valspar Season Flex Ultra white semi-gloss exterior to paint the interior of a new trailer I just recently purchased. The material that was painted over was new OSB.
There are spots that bled through.
Do you have a recommendation on the white semi-gloss paint I should use to cover up the staining?
Thank you very much for the help. I really appreciate it.

Spot prime those spots using a Pigmented Shellac Sealer Primer…
Good Luck!
