RadonSeal Standard Concrete Sealer, Deep-Penetrating Clear Protectant, 5-Gallon – Indoor & Outdoor Waterproofing for Poured Surfaces, Basement Floors,

RadonSeal Standard Concrete Sealer, Deep-Penetrating Clear Protectant, 5-Gallon – Indoor & Outdoor Waterproofing for Poured Surfaces, Basement Floors,

Basement Waterproofing & Radon Mitigation – Penetrates and seals concrete below the surface, blocking pores to reduce water, moisture vapor, and efflorescence infiltration. Ideal for basement walls, foundation walls, slabs, crawlspaces, and poured concrete walls. Concrete Densifier – Strengthens and hardens concrete surfaces, reducing cracks, dusting, spalling, and damage from road salts, de-icing chemicals, freeze-thaw cycles, abrasion, and general wear. Permanent – No reapplication required. Penetrates and chemically bonds deep within the concrete, becoming an integral part of the structure. Resistant to hydrostatic pressure, it won’t peel, crack, or fade, delivering permanenet protection. Easy To Apply – Water-based, zero VOC formula, safe to apply for both indoor and outdoor use. Safeguards - Improves performance, providing lasting protection for concrete driveways, patios, sidewalks, pool decks, garage floors, and retaining walls against wear, damage, and the effects of weather and traffic. RadonSeal Standard Deep-Penetrating Concrete Sealer provides permanent protection for concrete, making it an ideal sealer for use in basement waterproofing and radon mitigation projects. RadonSeal Standard is a water-based, zero-VOC silicate sealer engineered to seal and strengthen concrete slabs, basement walls and floors, garage floors, foundation walls, cellars, carports, driveways, patios, sidewalks, and crawlspaces. Formulating a deep crystalline structure within the concrete, RadonSeal penetrates up to 4 inches, sealing pores, blocking capillary tracts, and resisting negative-side hydrostatic pressure and efflorescence. It densifies and hardens concrete, reducing water seepage, water vapor transmission, moisture intrusion, soil gases, and concrete dusting. By strengthening the concrete matrix, RadonSeal helps prevent cracking, pitting, and spalling, while improving long-term durability, especially in areas exposed to freeze-thaw cycles and road salts. It also helps lower dampness and humidity in basements and crawlspaces, contributing to a healthier indoor environment. Suitable for both indoor and outdoor applications, RadonSeal-treated surfaces remain fully compatible with concrete paints, epoxy coatings, adhesives, tiles, and overlays, offering excellent finishing flexibility. Safe around landscaping, it is easy to apply with a standard hand-held pump sprayer and provides approximately 1,000 sq. ft. of coverage per 5-gallon pail on poured concrete. RadonSeal is fully paintable, making it an excellent base for epoxy coatings, clear coatings, tiles, adhesives, concrete overlays, and self-leveling compounds. By internally sealing and densifying the concrete, RadonSeal helps extend the lifespan of surface coatings, improving adhesion and reducing the risk of peeling, flaking, bubbling, or delamination caused by moisture vapor or efflorescence. For interior concrete under 20 years old or outdoor concrete under 3 years old, RadonSeal Standard is the recommended choice. For older concrete, use RadonSeal Plus. Protect and preserve your concrete while reducing moisture, dampness, and efflorescence with RadonSeal, the permanent deep-penetrating silicate sealer for slabs, foundation walls, basements, crawlspaces, driveways, patios, and more.
