Tannin seeping through painted oak cabinets
by

How do I prevent tannin from seeping through white painted oak cabinets? I have re-sanded, re-primed with Kilz and re-painted with satin enamel 3 times on one small area of one cabinet door, but the tannin keeps coming through and leaves a mustard yellow stain. Since priming doesn't seem to prevent this, does anyone know what will stop this from happening over and over?

shellac. Have never needed to do this but have read about this solution many times.
You can get tannin blocking primers, Zinnzer makes one. There are also paint additives that will block as well. i Would use both. If that doesn’t work, I’d go with oil based paint and primer, again, with additives for the tannin. Also check for exterior wood primers, these are usually formulated with tannin blocking.
I would use oil-based Zinseer B-I-N which is a shellac primer that prevents wood resins from seeping through. https://dengarden.com/home-improvement/Tips-for-Painting-Oak-Cabinets
