Waterproofing products do not always seal against radon. Radon can break down certain products over time.

The most important aspect of using any product on concrete is to have a clean, dry surface, free from oils.

Thanks

I think that was the company. And I know I need to do some work on the concrete floor, as a lot of places have cracked or broken. I'm wondering if I could just patch it or if I need new concrete put down.

Anyone have any experience with Sani Tred? All the contractors who have called are recommending using thick epoxy paint instead.

Thanks again,

All epoxy "coatings: are not created equal. Most epoxy paints will sit on top of the concrete and not have a good bond.

I have tried a variety of epoxy paints including Rustoleum and have found them to be inferior products designed to make you come back and buy more every few years.

Good quality epoxy will be a 1:1 plural system and cannot be bought at Home centers. You want an epoxy that will be absorbed into the concrete.

Talk to the good people at GoldenLook in Texas...maybe they can point you in a direction. 817-540-3000

Or contact your local Sherwin William Industrial center (not home center).

Here is a link to the products that I would consider being of good quality. I'm not sure if they will sell to you unless you are a business. If you are in the Boston area, I could help you with the purchase if needed.

Thanks again for the info.

Actually live in Cambridge, but the house we just purchased is in Providence. Need to get this all done before we move Jan 1.

Would love some help -- my email is [email protected]

The basement is dry, but there is this ledge around the high side. Inspector said it had "drylock" on it

Anyone know why this "ledge" is there? it's pretty loose stuff under.

Thanks for all the help

I know before I seal with epoxy or anything else I will need a clean surface. Anyone know the best filler or patch for the floor that will then accept the sealer?

Or do I need to lay down poured concrete?

Here's link to my basement photos. Any help appreciated

Most concrete products require atleast 14 days of cure time before you can use an epoxy product without delamination issues.

I find most cement products will not bond well to an existing floor. You can always fill in low areas with an epoxy/sand slurry or an epoxy/cab-o-sil mix.
