Zinsser Cover Stain Oil-Based Primer

Seems to work just fine.

Covers good need two coats though

Really happy with this paint did an amazing job covering the vinyl wallpaper in my mother's kitchen 2 coats covered the black no problem and dries quickly has a bit of a fuel smell to it but it dissipates quickly and for the coverage it gives it's so worth it

This stuff is Fantastic. It covered a large raw wood surface, knots and all, quite well using two coats. I painted my project outside in the yard, and I didn't need a mask. As for the smell, I would rate the fumes a 4 out of 10 for overall noxiousness. Clean up is not water, but with mineral spirits.

Gets the job done! The smell is extremely potent — highly recommend an air purifier and a respirator mask. It dries quickly & the quality is good. Good price for what you get.

These were as described.

This primer worked well to seal water stains on a ceiling due to poor roofing job

For jobs that require oil-based primer (e.g., re-glazing windows with linseed-based putty), this primer is the best. It covers nicely, dries relatively quickly and has an amazingly long shelf life in the can. (The only reason I needed to get a new can was because I finally reached the bottom of the can I bought 10 years ago!) Working with oil-based anything is never a pleasant experience, but if you have to use it, I would highly recommend this brand (along with a few pairs of thin latex gloves). 5 stars.
