RadonSeal Plus Concrete Sealer – Deep Penetrating Sealer for Basement & Foundation Walls and Floors, Helps Reduce Moisture Vapor, Strengthens Concrete Surfaces (2.5 Gallon)
Product Description
RadonSeal Plus Concrete Sealer – Deep Penetrating Sealer for Basement & Foundation Walls and Floors, Helps Reduce Moisture Vapor, Strengthens Concrete Surfaces (2.5 Gallon)
- DEEP-PENETRATING CONCRETE SEALER – RadonSeal Plus penetrates deep into concrete and reacts within the pore structure to seal capillaries, helping reduce water intrusion and moisture vapor transmission through basement floors and foundation walls.
- FOR BASEMENTS & FOUNDATIONS – Helps reduce moisture seepage through concrete floors and walls by penetrating and reacting within the concrete. Ideal for basement floors, foundation walls, slabs, and concrete block exposed to ground moisture.
- LONG-LASTING INTERNAL SEAL – Unlike acrylic or epoxy coatings that sit on the surface, RadonSeal reacts inside the concrete to form a durable internal seal that will not peel, blister, or wear away over time.
- STRENGTHENS & HARDENS CONCRETE – Chemically densifies and reinforces porous or weak concrete, reducing dusting and improving resistance to water intrusion, salts, and freeze-thaw cycles.
- EASY DIY APPLICATION – Apply with a sprayer, roller, or brush. The water-based formula penetrates deeply into the concrete where it reacts and cures internally—no surface coating or film.
- PAINTABLE & COATING-COMPATIBLE – Prepares concrete surfaces for coatings by helping reduce moisture movement through the substrate. Compatible with concrete paints, epoxy coatings, clear sealers, overlays, and adhesives.
- IDEAL FOR BASEMENTS & FOUNDATIONS – Suitable for basement floors, foundation walls, concrete slabs, garages, and warehouses. Works on poured concrete and concrete block (CMU) foundations.
- COVERS UP TO ~500 SQ FT PER 2.5 GALLONS – Coverage varies depending on concrete porosity. Suitable for basement floors, foundation walls, slabs, and concrete block to help reduce moisture vapor transmission.
- NATURAL, INVISIBLE FINISH – Does not change the appearance of concrete. No gloss, no darkening, and no surface film.
Waterproofing is not always easy but, with a little know-how and the right advice long-lasting solutions can be accomplished relatively inexpensively. Since 1997, RadonSeal® has been dedicated to offering contractors and homeowners unbiased expertise, unparalleled service and our commercial-warrantied sealers and concrete repair products. RadonSeal Plus is formulated to permanently seal more porous concrete; poured concrete (+20 years), concrete blocks, and most cinder blocks. Penetrates into concrete (up to 4"), chemically reacts, sealing the micro- capillaries and fractures that make concrete porous. RadonSeal restrict moisture, water vapor, and radon gas directly through concrete, helping to alleviate efflorescence, dampness, and humidity making it ideal for use in basements. Alternatively, use RadonSeal to strengthen deteriorating concrete, compromised pours, greatly reduces pitting, spalling due to freeze-thaw, road salts, and deicing chemicals. ZERO VOCs. Eco-friendly. Safe Use Indoors. USES: Basement floors, foundation walls, driveways, sidewalks, patios, garage floors, building facades, concrete barriers, carports,, and similar (Note - Polished, overly smooth, machine-troweled surfaces require acid etching or scarification). COVERAGE (apx): Poured Concrete -500 sq. ft., Concrete Block - 250 sq. ft., Cinder Block - 200 sq. ft. Concrete is complex and varies in composition and finishing techniques. Always test spot to ensure proper absorption. Sample bottles are available upon request. LIMITATIONS: Do not use on paint, grout, overlays, colored concrete, split face blocks, stamped concrete, reinforced concrete, bluestone, pavers. For successful radon mitigation of a basement, make sure to seal all the concrete, repair all cracks, and openings. Allow RadonSeal to cure for 6-8 weeks before retesting.
