I already have a painted surface that was obviously NOTwell enough prepped; there is primer and at least two coats of water-based paint over several knots that have bled thru all that; can I still sand and apply Zinnser cover stain effectively ?
Hi Colourakid, We recommend our Zinsser BIN Shellac Based Primer as this is recommended for knots.

is cover stain- stain killer poison? I felt nausea after painting.
Cover Stain is safe to use, but does contain solvents. Care must be taken when applying this product. Personal protective equipment, and good ventilation are important. If symptoms persist, always see your doctor.

Yes, Zinsser Cover Stain can be applied to a stucco ceiling. Once the Cover Stain is dry for at least two hours, it can be topcoated with the oil, or waterbased paint of your choice.

Primer-Sealer Stain Killer Cover Stain(R) - 3.78 L - White is rated out of 5 by 1.
Rated 4 out of 5 by PainteRon from Lock & Block the walls As a pro painter I use this product sparingly as the application of this product requires proper ventilation and respirator. It's an oil based product and does the job every time. It locks in odors and blocks out stains. For 'smoker' homes, this is the product of choice. We used bowls of white vinegar - post application to help deal with the smell as it was cold out. It says it dries quickly, roughly 2hrs, however we let it cure overnight before applying the latex topcoat. This product has its purpose and does what it says. Choosing and using the right primer is important.
