An acrylic bonding primer designed to provide excellent adhesion to wood and smooth masonry surfaces, this acrylic Exterior Primer/Sealer also binds chalky and worn surfaces, and resists checking and cracking over bare exterior masonry, stucco, plywood, pine, cedar and redwood. It also resists tannin-wood bleed, nail head rust and pine sap stains from leaching up into the topcoat. It dries fast, hides and levels well, and applies easily. It is highly alkali resistant and may be applied to new, dry concrete or masonry surfaces with a pH up to 13.0 and prior to a 30 day cure. It applies at temperatures as low as 35°F.
