Can you mix polyurethane with acrylic paint?
Did it today since nobody knew. I used water based poylurethane and acrylic craft pain-metallic. Worked great, looks great. I'm doing a powder room remodel. Painted trim and b…ase boards in acrylic colors that i mixed, but felt it need more. No problem. One thing i will say, watch how much paint you use. It depends on how much coverage you want. I only wanted a glazing. I also don't think you could get full coverage without multiple coats. Better to paint your color, then poly. I wanted a more antique look. Worked great. Good luck. I,m all about the projects. Big and small. (MORE)

NOT TRUE, SIR, as I was personally being poisoned by exposure to the off-gassing, and my health only improved after replacing the mattress.
