For bathrooms, kitchens, doors, floors, closets, and cabinets. For oils, clears, and enamels. For smooth and semi-smooth surfaces. Doesnt leave unsightly fuzz, lint or seam marks. Foam conforms to surface irregularities and provides contour coverage. Willnot "mat down". Has a "reservoir action" and carries most of the paint below the surface in thousands of tiny open cells. Less frequent "dipping" and less "spreading out" of paint. Cleans quickly and easily.
