  • DEEP-PENETRATING CONCRETE SEALER – RadonSeal Plus penetrates deep into concrete and reacts within the pore structure to seal capillaries, helping reduce water intrusion and moisture vapor transmission through basement floors and foundation walls.
  • FOR BASEMENTS & FOUNDATIONS – Helps reduce moisture seepage through concrete floors and walls by penetrating and reacting within the concrete. Ideal for basement floors, foundation walls, slabs, and concrete block exposed to ground moisture.
  • LONG-LASTING INTERNAL SEAL – Unlike acrylic or epoxy coatings that sit on the surface, RadonSeal reacts inside the concrete to form a durable internal seal that will not peel, blister, or wear away over time.
  • STRENGTHENS & HARDENS CONCRETE – Chemically densifies and reinforces porous or weak concrete, reducing dusting and improving resistance to water intrusion, salts, and freeze-thaw cycles.
  • EASY DIY APPLICATION – Apply with a sprayer, roller, or brush. The water-based formula penetrates deeply into the concrete where it reacts and cures internally—no surface coating or film.
  • PAINTABLE & COATING-COMPATIBLE – Prepares concrete surfaces for coatings by helping reduce moisture movement through the substrate. Compatible with concrete paints, epoxy coatings, clear sealers, overlays, and adhesives.
  • IDEAL FOR BASEMENTS & FOUNDATIONS – Suitable for basement floors, foundation walls, concrete slabs, garages, and warehouses. Works on poured concrete and concrete block (CMU) foundations.
  • COVERS UP TO ~500 SQ FT PER 2.5 GALLONS – Coverage varies depending on concrete porosity. Suitable for basement floors, foundation walls, slabs, and concrete block to help reduce moisture vapor transmission.
  • NATURAL, INVISIBLE FINISH – Does not change the appearance of concrete. No gloss, no darkening, and no surface film.
