Invisible Deep-Penetrating Clear Masonry Waterproofer
BEHR PREMIUM® Concrete & Masonry Protector & Waterproofer provides an efficient, long-lasting solution for preserving exterior stone, brick, and concrete without changing your home’s aesthetics. Standard topical sealers leave behind a shiny plastic film that eventually cracks or peels. This advanced penetrating compound moves deep inside mineral capillaries, coating pore paths with a durable water-beading shield. This stops driving rain from saturating the masonry core, completely halting frost cracking, freeze-thaw spalling, and white efflorescence salt stains.
Best Used For:
• Exterior unpainted concrete block walls, brick accent walls, chimneys, and stucco facades
• Concrete sidewalks, residential driveways, patios, pool decks, pavers, and retaining structures
• Protecting porous natural stones, unglazed slates, and fiber cement sheets outdoors
• Note: Designed for above-grade vertical and horizontal surfaces. Not intended for interior basement waterproofing under hydrostatic pressure.
Key Benefits & Features:
• Deep Penetration Shielding: Migrates deep into porous surfaces to establish a water-repellent layer that protects against damage from freezing temperatures and heavy rains.
• Anti-Efflorescence Defense: Shuts down the migration of subsurface salts to the face of the stone, keeping your masonry clean and free from white powdery stains.
• Natural Aesthetic Preservation: Clear formula dries completely matte and clear. It leaves no glossy film, wet-look shine, or color alteration behind.
• Clean Application Profile: Water-based, low-odor formula features low VOCs, making it comfortable to apply around landscaping and family zones.
Technical Specifications:
• Resin Base Type: Water-Based Acrylic Silicone
• Coverage Capacity: 150 to 400 sq. ft. per gallon depending on substrate porosity
