I need a paint to cover polyurethane foam. Also, the coverage per sq. feet and cost per gallon. This is an exterior job.
Plan on priming the foam with an exterior acrylic primer before painting. The primer should cover 200-250 sq/ft per gallon. Any good exterior acrylic paint can be put over the primer. Coverage should be 250-300 sq/ft per gallon. The cost per gallon depends on your supplier and the products you choose.
