It chemically strengthens concrete, preventing cracks, dusting, and damage from freeze-thaw cycles and de-icing salts. With zero VOCs and a non-toxic formula, it’s safe for indoor and outdoor use on poured concrete surfaces like basements, driveways, and patios. RadonSeal also acts as a primer for paints and coatings, offering versatile, long-lasting protection without the need for reapplication. ## Description RadonSeal - Basement Waterproofing & Radon Mitigation. The permanent concrete Sealer for long lasting protection. Since 1997, RadonSeal has been the go-to choice for high-quality concrete waterproofing sealers, with over 25 years of expertise in basement concrete sealers, penetrating sealers, and moisture control. Our RadonSeal Deep-Penetrating Concrete Sealer is a water-based, silicate sealer with a zero VOC formula, engineered to seal and protect concrete slabs, basement walls, basement floors, garage floors, foundation walls, cellars, and crawlspaces. This advanced sealer penetrates up to 4 inches into concrete, forming a permanent crystalline structure that seals pores, blocks capillary tracts, and resists negative-side hydrostatic pressure, efflorescence, and harsh chemicals. By reducing water seepage, water vapor transmission, moisture, radon gas, and concrete dusting, RadonSeal strengthens surfaces, making them denser, more durable, and resistant to cracking, pitting, and spalling. It also aids in reducing dampness, humidity, and musty odors in cellars and crawlspaces, creating a healthier environment. Ideal for indoor and outdoor applications, RadonSeal protects concrete driveways, pool decks, patios, sidewalks, and garage floors. It protects damage from freeze-thaw cycles and road salts, ensuring long-term durability. Treated surfaces are compatible with concrete paints, epoxies, adhesives, tiles, and overlays, providing finishing versatility with permanent protection. Non-toxic and safe for vegetation and pets, RadonSeal is easy to apply using a handhels pump sprayer and offers approximately 1,000 sq. ft. of coverage per 5-gallon pail. For interior concrete under 20 years old or outdoor concrete over 3 years old, choose RadonSeal Standard. Protect your concrete, eliminate dampness, moisture, and efflorescence with RadonSeal—the advanced silicate sealer for concrete slabs, foundation walls, cellars, crawlspaces, garage floors, and patios.

It does not form a film, allowing the concrete to remain breathable. **Q: Can I apply paint, epoxy, or coatings over RadonSeal?** A: Yes. When applied to a bare, porous surface, it absorbs into the concrete rather than forming a surface layer, allowing proper adhesion of paints, epoxy, levelers, and coatings. **Q: What is the coverage rate?** A: • Poured Concrete: 175–225 sq. ft. per gallon • Concrete Block: 100–125 sq. ft. per gallon As a general guideline, a 1,000 sq. ft. poured concrete surface requires approximately 5 gallons. A 2.5-gallon container will cover about 500 sq. ft. **Q: Will RadonSeal stop water leaks through cracks?** A: RadonSeal is not designed to stop active leaks through cracks, joints, or seams. These areas should be repaired using appropriate products such as CrackWeld Floor Crack Repair Kit or RadonSeal DIY Foundation Crack Repair Kit. **Q: Can RadonSeal be applied to painted or sealed surfaces?** A: No. RadonSeal must be absorbed through the surface to be effective. It should only be applied to clean, bare, and porous concrete. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Un must *by J***G on 8 February 2026* Produit merveilleux et vraiment un bon deal qualité/prix . ### ⭐⭐⭐⭐⭐ Works great *by K***T on 25 May 2026* Works great and easy to apply ### ⭐⭐⭐⭐⭐ Easy to use *by B***O on 24 November 2025* Easy to apply with a sprayer and sealed using little product, I had a lot left over.
