## Overview

RadonSeal Standard is a professional-grade, deep-penetrating silicate concrete sealer that permanently waterproofs and densifies indoor and outdoor poured concrete surfaces. It blocks water, vapor, radon gas, and efflorescence by chemically bonding up to 4 inches deep, enhancing durability against cracks, freeze-thaw cycles, and chemical damage. This eco-friendly, zero VOC formula is safe, easy to apply, and compatible with paints and coatings, making it the go-to solution for lasting basement, driveway, and slab protection.

## Description

RadonSeal - Basement Waterproofing & Radon Mitigation. The permanent concrete Sealer for long lasting protection. Since 1997, RadonSeal has been the go-to choice for high-quality concrete waterproofing sealers, with over 25 years of expertise in basement concrete sealers, penetrating sealers, and moisture control. Our RadonSeal Deep-Penetrating Concrete Sealer is a water-based, silicate sealer with a zero VOC formula, engineered to seal and protect concrete slabs, basement walls, basement floors, garage floors, foundation walls, cellars, and crawlspaces. This advanced sealer penetrates up to 4 inches into concrete, forming a permanent crystalline structure that seals pores, blocks capillary tracts, and resists negative-side hydrostatic pressure, efflorescence, and harsh chemicals. By reducing water seepage, water vapor transmission, moisture, radon gas, and concrete dusting, RadonSeal strengthens surfaces, making them denser, more durable, and resistant to cracking, pitting, and spalling. It also aids in reducing dampness, humidity, and musty odors in cellars and crawlspaces, creating a healthier environment. Ideal for indoor and outdoor applications, RadonSeal protects concrete driveways, pool decks, patios, sidewalks, and garage floors. It protects damage from freeze-thaw cycles and road salts, ensuring long-term durability. Treated surfaces are compatible with concrete paints, epoxies, adhesives, tiles, and overlays, providing finishing versatility with permanent protection. Non-toxic and safe for vegetation and pets, RadonSeal is easy to apply using a handhels pump sprayer and offers approximately 1,000 sq. ft. of coverage per 5-gallon pail. For interior concrete under 20 years old or outdoor concrete over 3 years old, choose RadonSeal Standard. Protect your concrete, eliminate dampness, moisture, and efflorescence with RadonSeal—the advanced silicate sealer for concrete slabs, foundation walls, cellars, crawlspaces, garage floors, and patios.

*by S***N on 31 July 2013*

Great Product, it works as described. make sure you clear out all your stuff from walls and floors to make it easier to apply. It's literally as simple as spraying water, just get a pump sprayer (not a used one with bug chemicals in it), use the sprayer to dampen the floor/wall with water, then use the sprayer to coat the floor/walls with radon seal, before it drys recoat with radonseal again....easy! My basement was floating around 13+ for Radon measure by an electronic radon meter, I applied the radon seal and vented the basement for over a week and used a dehumidifier to get the moisture out and help dry. After I closed the basement back up I'm now around 8 for radon, but the high levels I'm sure are because I still need to cover my sump pump pit which has open dirt around it and my radon tubes don't have fans yet, so I still have some work to do but the area where my carpet is at and the exposed walls I feel i don't have to worry about since I put radon seal down before they installed the floor.
