This is not what we expect to hear, Ken! For the best consistency, it is essential that Rust-Oleum Zinsser Perma-White Mold and Mildew-Proof Interior Paint is thoroughly mixed prior to each use and stirred often during your application to prevent settling. This product works best on new or previously painted gypsum drywall, cured plaster, cement, poured concrete and stucco, concrete block, ceramic tile, primed or previously painted wood and metal, paneling, rigid paintable plastics, and laminates.
