For painting small areas like furniture, cupboards, cabinets, etc. For latex, acrylic, and alkyd paints. Doesnt leave unsightly fuzz, lint or seam marks. Foam conforms to surface irregularities and provides contour coverage. Will not "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.
