Cabot Problem-Solver Acrylic Primer is an acrylic-based, exterior primer that is uniquely formulated to provide resistance to extractive bleeding, stains from mildew and moisture problems. Its acrylic formula remains flexible, resisting cracking, peeling or blistering. This premium quality primer makes an ideal base coat for Cabot O.V.T.® Solid Color Acrylic Stains as well as other solid color acrylic latex stains and paints. It provides excellent adhesion on newly erected, smooth, shiny (mill glaze) siding and lumber, thereby eliminating the need to weather or season new, smooth wood for long periods of time. Cabot Problem-Solver Acrylic Primer is easy to apply, easy to clean up and dries quickly. It is recommended for use on new or previously stained surfaces including wood siding, trim, shingles, plywood, manufactured hardboard, engineered wood products, cured stucco, masonry, brick, asbestos siding, cementitious siding and smooth or rough-sawn surfaces. It is suitable for use on woods such as incense cedar, red cedar, fir, pine, cypress, spruce and redwood.
