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.

I can only assume it is a five-star product. According to its label if it does everything it says it's going to do it should be wonderful. The fact of the matter is you can't see with your eyes what's going on inside the walls so hopefully it will work as anticipated and as specified.

This product really worked for me. My radon went from 6.0 to 1.5 -2.00. Craig in customer service is so kind and knowledgeable. I like him as he does not sugar coat anything and took so much time on how to put the product on and what the product actually does for your concrete. I am totally sold on this product and a truthful person like Craig. Thank you so much, Craig. A plus service and product!!! Now to buy more 😊

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.

We used this product to seal a newly laid concrete garage floor. We bought a spray device for $12 on Amazon to lay the sealer, and it was easy and perfect. The amount of sealer was perfect for a three car garage with some left over. Would definitely purchase again.
