Q:Will it repell oil stains
by|Oct 12, 2023
1 Answer
Answer This Question

A:  Thank you for your question! RadonSeal Plus is not an oil-repellent sealer. If you need a surface-repellent product, our DryWay/DryWay Plus Water Repellent Concrete Sealer would be the appropriate choice. Cheers, ---------- Craig - Product Expert RadonSeal®

        Q:Can I use this on concrete patio pavers ?
        by|May 22, 2023
        1 Answer
        Answer This Question

        A:  RadonSeal is not best for pavers. Use our RadonSeal Penetrating Paver Sealer. An silane/siloxane blend that will protect against salts, stains, freeze/thaw, and will repel water for up to 10-years.

            I monitored my radon levels with an electric radon detector for over a month and it stayed right around 11 for long term and 7 day readings. After following the application steps better than most probably can (I had a very clean floor to begin with) for my entire unfinished basement floor (applying 2 "wet on wet" coats) and filling all cracks after the application, my levels remain at 11. This did absolutely nothing to help with radon levels. I took a risk on buying two buckets so I could do the recommended 2 coats everywhere and it was a bust. Also, it's been 3 weeks since applying the two coats with no change whatsoever in radon levels for the entire 3 weeks.

            Its quite surprising that after repairing all your cracks and sealing your foundation and slab with RadonSeal, you saw no change to your radon levels. Where else could the radon be entering your basement? Sump pit? Floor drains? I would be interested in talking about your situation in more detail. Please call when you have time to discuss. 800 472 0603

              So far, the application appears to have improved the dampness situation considerably. However, we have not had any of the heavy rains like we experienced in early January, so the jury is still out for a bit longer until we get more rain and see if the desired waterproofing effect is in fact effective.

              Directions were more complicated the the description, low odor was good. will have to see if it stops water seeping up through the floor, hopefully it will.
