RadonSeal Standard Penetrating Concrete Sealer (2.5-gal) | Radon & Moisture

Description

RadonSeal® Standard Concrete Sealer
- Permanently Seals Concrete against Water Seepage, Moisture Vapor, Efflorescence, and Radon Gas. Backed by a Lifetime Money-Back Guarantee!
RadonSeal® (est. 1997) has been the most trusted and widely-used concrete sealer for both commercial construction and residential projects. RadonSeal is a reactive, internal sealer for concrete, mortar, and other cementitious
materials. The sealer penetrates deep into concrete
(up to 4")
, reacts, expands inside the concrete pores and cures as a hard silicate mineral.
THE SEAL IS PERMANENT!
Unlike common surface sealers
(membrane coatings)
or waterproofing paints sold in stores, RadonSeal will never peel off or wear away. There is no need to ever reapply the product again! Once RadonSeal has cured inside the concrete, it can not be pushed out regardless of hydrostatic pressure. The seal becomes integral to the concrete providing hardness and durability.
Prevents concrete pitting and spalling due to freeze-thaw, road salts, and chemicals. Hardens the surface. Stops efflorescence and concrete dusting.
Think of it like injecting more cement into the concrete!
USE TO WATERPROOF CONCRETE WALLS AND FLOOR
– RadonSeal is the heaviest available silicate-based sealer, which penetrates deeper, carries more active minerals, and seals tighter than any other concrete sealer. The penetration does not depend on gravity – it is also commonly used for sealing foundation walls and basement floors. In case of basement walls, RadonSeal® Standard is normally applied to poured concrete walls to seal against water seepage, water vapor, and radon gas from the ground. However, if there is an opportunity to apply it to the outside, it has the added advantage of preserving the exterior of the concrete and extending the life of waterproofing coating.
OTHER USES
:
Gunite pools, concrete koi ponds. Strengthens concrete driveways, sidewalks, decks, poured concrete pool decks, parking lots, concrete ramps, and similar.
USE BEFORE PAINTING CONCRETE
– Because RadonSeal protects concrete against water vapor, efflorescence, and the "alkali attack" it is commonly used before applying paints, adhesives, epoxy floor coatings, concrete overlays, surface levelers, clear "wet-look" surface coatings, and before the installation of moisture sensitive flooring.
STRENGTHENS OLDER CONCRETE
– Once cured, RadonSeal makes concrete denser and stronger
(up to 40% in flexural strength)
. Use on porous concrete surfaces to reduce dusting, crumbling, and overall wear.
Safe and easy spray-on application for homeowners or contractors.
Environment-friendly, non-hazardous sealer with no fumes or noxious odors. Contains zero VOCs.
COVERAGE:
2 applications will cover 500 sq. ft. for poured concrete.
