I don't know. I used it in a totally different application, I used it for painted concrete which was already rough.

It is not seal and enhance. It is charcoal colored caulk. I had to return it.

Radon seal does not change the finish of the concrete. It soaks into the concrete and seals it. Follow the instructions, don't let puddle and dry. Brush the concrete well after a week and do not paint for at least 10 days as stated in the instructions. Radon seal only seals the concrete it is not used as a finishing product. I would get all of the information from radon seal on line before purchasing and using. I have used it but since it soaks in and does not change the look of the concrete it is difficult to determine how well it works.

In the times I have used Flex Seal, it has worked in all instances to stop leaks. I have use it around basement concrete to stop rain leaks, and I have use it in down spouts to stop water leaks. I have use the white color option.

I used it around my basement windows but around where the concrete and window meet but I will frame the basement 'someday' and it will be covered by trim. If you're wanting to seal a window so it cannot open and close you will have a hard time removing this stuff. You would be better off with clear plastic and tape or use one of those window insulator kits.

Yes, but you need to test the moisture first before apply it on, epoxy flood need the concrete to at least 1 year old and moisture is another thing to avoid. A method to test is to tape down a 3 x 3 piece of plastic tarpaulin for two days and then check it to see if there is moisture gathered on the underside of the plastic. If moisture is present, consider some other form of coating.

Hi It will not close cracks You should fill those first with a cement based filler and the sealer will then seal the filler plus the original concrete Regards Mike 423-503-4490

We used it to seal small (1/16") cracks in concrete after mixing it with Portland cement...so far the basement has been dry even on very rainy days when before we would get several gallons of water. Have not used it directly as a paint.

I used it to seal marble. And will reseal once a year. Haven't found recommendation by manufacturer.

This sealer claims to prevent radon gas from penetrating through a sealed concrete surface. It did not mitigate the radon in my basement at all. I sincerely doubt this sealer will harden your silt stone and prevent it from breaking and flaking.

I don't know. I didn't buy it to use concrete. I bought it to paint a pattern on my patio, which I did not do and ended up getting rid of the mold.

Yes, it is a clear sealer, but it needs to be wiped off the tile after application. It seemed to work better than other sealers I have used in the past.

The RadonSeal does not alter the finish of the concrete. After complete drying, the floor looks the same as it did before the application if you follow the directions. If you have areas of gloss before the sealing, you will still have them afterward.

It should create an effective seal on most materials. My application was on a ceramic and cast iron sink.

I haven't a clue about using it on concrete. I use it on wood to seal the surface so water doesn't penetrate and stain the wood. You have to reapply it as it wears away. It is perfect for cutting boards and butcher block surfaces.

No. It's a suction cup and needs hardened material to get the seal needed to stick
