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.
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.

## Features

- Basement Waterproofing & Radon Mitigation – Penetrates and seals concrete below the surface, blocking pores to reduce water, moisture vapor, and efflorescence infiltration. Ideal for basement walls, foundation walls, slabs, crawlspaces, and poured concrete walls.
- Concrete Densifier – Strengthens and hardens concrete surfaces, reducing cracks, dusting, spalling, and damage from road salts, de-icing chemicals, freeze-thaw cycles, abrasion, and general wear.
- Permanent – No reapplication required. Penetrates and chemically bonds deep within the concrete, becoming an integral part of the structure. Resistant to hydrostatic pressure, it won’t peel, crack, or fade, delivering permanenet protection.
- Easy To Apply – Water-based, zero VOC formula, safe to apply for both indoor and outdoor use.
- Safeguards - Improves performance, providing lasting protection for concrete driveways, patios, sidewalks, pool decks, garage floors, and retaining walls against wear, damage, and the effects of weather and traffic.

### ⭐⭐⭐⭐⭐ 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. It left a white milky staining but appears to have done its job. Was not as costly as other sealers.

### ⭐⭐⭐⭐⭐ Good product, great customer service
*by D***B on February 9, 2021*

Product comes in a pail with convenient pour spout. 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.
