RadonSeal PLUS Deep-Penetrating Concrete Sealer is a water-based, Zero VOC, concrete sealer formulated to permanently seal, strengthen, and protect poured concrete, concrete blocks, and limestone. RadonSeal works by absorbing deep below the surface to seal the pores and capillaries that make concrete porous. It hardens within the concrete as a mineral and withstands both negative and positive-side hydrostatic pressure. RadonSeal is permanent and does not require reapplication.
Radon mitigation and waterproofing in one simple step!
RadonSeal protects against water seepage, water vapor transfer, and the migration of radon and other soils gases through concrete walls and floors. Permanently strengthens, hardens concrete surfaces, and protects concrete against cracking, dusting, efflorescence, freeze-thaw, road salts, deicing chemicals, and minor defects. Use RadonSeal before painting, installing flooring, coatings, or overlays to extend the life of these products by reducing negative-side moisture transfer.
