RadonSeal and RadonSeal PLUS

Penetrating Concreate Sealer

Easy & Safe – Environmentally Friendly – No Re-Application Required

RadonSeal penetrates deep into concrete, reacts, and seals it permanently against water, vapor, and even radon gas. Seals basement floors and walls against water, dampness, efflorescence, molds, and even radon gas. Protects driveways and outdoor concrete against spalling or cracking due to freeze-thaw and road salts.

Use RadonSeal Standard on poured concrete and RadonSeal Plus on older poured concrete (over 20 years) or concrete blocks.

Easy application with a hand pump garden sprayer. No re-applications needed! Waterborne, non-toxic, zero VOCs. Eco-friendly.
