RD PRO® Siliconized Acrylic Caulk is a superior construction-grade sealant fortified with silicone for increased flexibility and extended life. It provides excellent adhesion to most building substrates and offers added bonding strength for durable, watertight seals. The caulk adheres to painted and unpainted wood, drywall, masonry, plaster, ceramic, glass, brick, metal, concrete, and more. It is ideal for window and door frames, countertops, baseboards, eaves, siding, thresholds, trim, vents, railings, joints, and more. This caulk should not be used for below-waterline applications, automotive applications, mirrors, aquariums, or joints subject to heavy abrasion or wear. Note: The surface must be clean, dry, and free from dirt, dust, grease, oil, mildew, wax, loose paint, frost, and old caulking before application; prime bare surfaces before caulking for best results. Protect from water for initial cure and prevent continual freezing and thawing to maintain quality.
