It permanently waterproofs by reducing moisture vapor and hydrostatic pressure effects without trapping moisture, while simultaneously strengthening and hardening concrete from within. Ideal for newer concrete surfaces, it minimizes efflorescence and dusting, improves paint adhesion, and protects against freeze-thaw damage—all with an easy, low-odor application. ## Description RadonSeal Concrete Sealer (Standard) – Deep Penetrating Waterproofing for Basement Floors & Foundation Walls – Reduces Moisture & Strengthens Concrete (5 Gallon) - Radonseal Plus - desertcart.com Review: Easy to use - Easy to apply with a sprayer and sealed using little product, I had a lot left over. It left a white milky staining but appears to have done its job. Was not as costly as other sealers. Review: Great Product - 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. ## Features - 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. ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | RadonSeal | | Color | Clear | | Compatible Material | Poured Concrete, Limestone | | Item Dimensions | 13 x 13 x 16 inches | | Item Form | Liquid | | Item Weight | 47.4 pounds | | Item dimensions L x W x H | 13 x 13 x 16 inches | | Material | Silicate Blend | | Style | Standard | | Style Name | Standard | | Surface Recommendation | Poured Concrete Walls & Floors | | Water Resistance Level | Waterproof | ## Product Details - **Brand:** RadonSeal - **Item Weight:** 47.4 Pounds - **Item dimensions L x W x H:** 13 x 13 x 16 inches - **Material:** Silicate Blend - **Style:** Standard ## Images ![RadonSeal Concrete Sealer (Standard) – Deep Penetrating Waterproofing for Basement Floors & Foundation Walls – Reduces Moisture & Strengthens Concrete (5 Gallon) - Image 1](https://m.media-amazon.com/images/I/81BBZ5ZkieL.jpg) ![RadonSeal Concrete Sealer (Standard) – Deep Penetrating Waterproofing for Basement Floors & Foundation Walls – Reduces Moisture & Strengthens Concrete (5 Gallon) - Image 2](https://m.media-amazon.com/images/I/61R9289J-PL.jpg) ![RadonSeal Concrete Sealer (Standard) – Deep Penetrating Waterproofing for Basement Floors & Foundation Walls – Reduces Moisture & Strengthens Concrete (5 Gallon) - Image 3](https://m.media-amazon.com/images/I/71mfvhY2heL.jpg) ![RadonSeal Concrete Sealer (Standard) – Deep Penetrating Waterproofing for Basement Floors & Foundation Walls – Reduces Moisture & Strengthens Concrete (5 Gallon) - Image 4](https://m.media-amazon.com/images/I/71XPIcXXl1L.jpg) ![RadonSeal Concrete Sealer (Standard) – Deep Penetrating Waterproofing for Basement Floors & Foundation Walls – Reduces Moisture & Strengthens Concrete (5 Gallon) - Image 5](https://m.media-amazon.com/images/I/713DheGmkYL.jpg) ## Questions & Answers **Q: How is RadonSeal different from coatings or sealers?** A: Unlike traditional coatings that sit on the surface and can peel or trap moisture, RadonSeal absrobs deep into the concrete and works below the surface. It does not form a film, allowing the concrete to remain breathable. **Q: Can I apply paint, epoxy, or coatings over RadonSeal?** A: Yes. When applied to a bare, porous surface, it absorbs into the concrete rather than forming a surface layer, allowing proper adhesion of paints, epoxy, levelers, and coatings. **Q: What is the coverage rate?** A: • Poured Concrete: 175–225 sq. ft. per gallon • Concrete Block: 100–125 sq. ft. per gallon As a general guideline, a 1,000 sq. ft. poured concrete surface requires approximately 5 gallons. A 2.5-gallon container will cover about 500 sq. ft. **Q: Will RadonSeal stop water leaks through cracks?** A: RadonSeal is not designed to stop active leaks through cracks, joints, or seams. These areas should be repaired using appropriate products such as CrackWeld Floor Crack Repair Kit or RadonSeal DIY Foundation Crack Repair Kit. **Q: Can RadonSeal be applied to painted or sealed surfaces?** A: No. RadonSeal must be absorbed through the surface to be effective. It should only be applied to clean, bare, and porous concrete. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy to use *by B***O on November 24, 2025* Easy to apply with a sprayer and sealed using little product, I had a lot left over.

Was not as costly as other sealers. ### ⭐⭐⭐⭐⭐ Great Product *by S***N on July 31, 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.

Is easy to apply with no apparent fumes (stated to have zero VOCs). Coverage depends entirely on the porosity of the concrete. I have already seen short term radon levels drop to levels I have not seen before. Outstanding customer service with rapid response to any inquiry. ## Frequently Bought Together - RadonSeal Standard Deep-Penetrating Concrete Sealer - Basement Waterproofing & Radon Mitigation - 5 Gals - Chapin 20000 Made in USA 1 -Gallon Lawn and Garden Pump Pressured Sprayer, for Spraying Plants, Garden Watering, Weeds and Pests, Polypropylene, Translucent White - RadonSeal Deep Penetrating Concrete Sealer for Basement Walls and Floors, Seals Concrete Against Water, Vapor and Radon Gas, (2.5 Gallons) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/11394484-radonseal-concrete-sealer-standard-deep-penetrating-waterproofing-for-basement-floors](https://www.desertcart.sn/products/11394484-radonseal-concrete-sealer-standard-deep-penetrating-waterproofing-for-basement-floors) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-08-14*
