  • DEEP PENETRATING CONCRETE SEALER – WATER & MOISTURE PROTECTION: Penetrates deep into concrete to reduce water penetration, moisture vapor, and efflorescence—helping keep basements drier and concrete protected.
  • PERMANENT, NON-COATING PROTECTION: Works inside the concrete—not on the surface—so it won’t peel, flake, blister, or wear off like waterproofing paints and coatings. Allows moisture vapor to escape—will not trap moisture within the concrete.
  • STRENGTHENS & HARDENS CONCRETE: This deep penetrating concrete sealer reacts within the concrete to densify and strengthen from the inside, reducing dusting, wear, cracking, and long-term deterioration.
  • REDUCES MOISTURE TRANSMISSION & HYDROSTATIC PRESSURE EFFECTS: Helps reduce moisture movement through concrete, including under hydrostatic pressure, improving overall basement and foundation performance.
  • REDUCES EFFLORESCENCE & DUSTING: Minimizes white mineral deposits and surface dust by sealing internal pores and capillaries.
  • PAINTABLE – IDEAL PREP FOR COATINGS: Improves adhesion for paints, adhesives, overlays, and epoxy coatings by reducing moisture vapor, efflorescence, and dusting.
  • IDEAL FOR NEWER POURED CONCRETE: Designed for newer, dense concrete slabs and foundation walls. For older or more porous concrete, including block, use RadonSeal PLUS.
  • EASY TO APPLY – LOW-ODOR, ZERO VOC FORMULA: Water-based, non-toxic formula safe for indoor use. Applies easily with a sprayer or roller.
  • USE ON BASEMENTS, FOUNDATIONS & SLABS: Ideal concrete sealer for basement waterproofing, foundation walls and floors, garage slabs, and other poured concrete surfaces where moisture reduction and durability are needed.
  • HELPS PROTECT AGAINST FREEZE-THAW DAMAGE: Reduces water penetration that leads to cracking, spalling, and surface deterioration—helping protect against damage from freeze-thaw cycles and de-icing salts.
