RadonSeal Deep-Penetrating Concrete Sealer - 2.5 gal.

Trusted Since 1997 - Pioneers in concrete care and repair. RadonSeal Plus Deep-Penetrating Concrete Sealer is formulated to permanently seal poured concrete and concrete blocks. RadonSeal penetrates into concrete (more than 4-inches), chemically reacts, and seals the capillaries and pores that make concrete porous. RadonSeal restricts moisture, water vapor, and radon gas infiltration through concrete. Ideal for damp, musty basements, cellars, and on-grade concrete slabs in areas with poor drainage.
