How is RadonSeal different from coatings or sealers?

Unlike traditional coatings that sit on the surface and can peel or trap moisture, RadonSeal absrobs deep into the concrete and works below the surface. It does not form a film, allowing the concrete to remain breathable.

Can I apply paint, epoxy, or coatings over RadonSeal?

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.

What is the coverage rate?

• 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.

Will RadonSeal stop water leaks through cracks?

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.

Can RadonSeal be applied to painted or sealed surfaces?

No. RadonSeal must be absorbed through the surface to be effective. It should only be applied to clean, bare, and porous concrete.

INVISIBLE YET INVINCIBLE - Seals concrete pores deep inside—no surface film, no gloss, just pure protection.
MOISTURES WORST ENEMY - Reduces water intrusion and moisture vapor transmission for healthier, drier basements and foundations.
DIY FRIENDLY PRO APPROVED - Easy application with sprayer, roller, or brush—perfect for savvy homeowners and pros alike.
BUILT TO LAST NOT JUST COVER - Internal chemical reaction forms a durable seal that won’t peel or wear off over time.
CONCRETES STRENGTH BOOSTER - Densifies and hardens weak or porous concrete, improving resistance to dusting, salts, and freeze-thaw damage.

RadonSeal Plus Concrete Sealer is a high-performance, water-based formula that penetrates deep into concrete and masonry to create a durable internal seal. Designed for basement floors, foundation walls, slabs, and concrete blocks, it reduces moisture intrusion, strengthens concrete by chemical densification, and lowers radon gas levels.
