Product Overview

RadonSeal Deep-Penetrating Concrete Sealer seals poured concrete and concrete blocks deeper and tighter than any other sealer on the market. The best basement sealer for your foundation walls and concrete floor against water seepage, vapor transmission and even radon gas. RadonSeal penetrates deep into concrete and reacts, sealing and preserving it permanently. Negative-side hydrostatic water pressure cannot budge it. It reduces basement humidity, prevents musty odors and basement molds. RadonSeal is the only basement sealer backed by a lifetime money-back guarantee against radon. It does not change the surface of the concrete. Treated surfaces remain suitable for paints, adhesives and overlays. Seal your concrete before painting it or installing flooring to avoid trapping moisture. Make sure to seal the basement walls and floor before finishing the basement to avoid water damage. RadonSeal prevents efflorescence and reduces concrete dusting, spalling and cracking. It cannot peel, fade or wear off. Results are permanent, no need for re-application. Safe and easy spray-on application, non-hazardous formulation, water-based sealer with zero VOC's. Trusted by contractors, building owners and DIY homeowners for more than 20-years.
  • Stop water seepage, moisture transmission and radon gas in 1 application
  • Safe and easy to apply, non-hazardous, no odor, dries quickly
  • Use on vertical and horizontal surfaces, indoors or out
  • Will not change the look or feel of your concrete, treated surface remain suitable for paints, tiles, adhesives and overlays

First big rain storm last night since I put it on, wall turning white again, means rain seeping through. Waste of money, and plenty of money.

I sprayed it on my basement block wall it really smelled when it was wet but that was the smell of the wall itself after it dried there was no more odor in the basement. It really does work. So I ordered more to also do the floors in the basement

I did not test the walls in the basement to see if they had radon, but just figured the smart thing to do was to seal it before painting the wall. It would be much harder to do after!
