I applied 2 coats of paint and primer and let dry for 2 days. I then applied a coat of spray on polyurethane , satin finish. After it dried some areas were yellow. I then sanded it down and applied another coat of my color, let that dry 2 more days. I bought a can of minwax satin finish polyurethane and applied 2 coats. Again there are yellow areas. I have down several painting projects and this is the first time I have had this problem.
What caused it and what should I do now to get rid of the yellow areas?
Oil-based polyurethane causes yellowing of white paint. It looks like the Minwax Satin Finish Polyurethane might be oil based, true? If so, I'd sand it down again (annoying, but necessary) and try again with a water-based poly. Then again, you might do well to just paint a few coats of satin finish paint instead of poly it, depending on what you're painting/what color you're using but that won't protect well if it gets a lot of use. Hope that helps!
The polyurethane was actually water based, not oil. I think i will just sand and apply several more coats of the color. If you have other suggestions I;m open. Thanks Sandy
