When this product is installed over a concrete floor, does the floor need to be sealed? Has anyone had any problems with mold with this product?

Hi Kim. No, you do not need to seal your flooring. Sealing your flooring may void any manufacturers warranty and you should consult your manufacturer prior to installation. No, we have not had any reports of mold or mildew with this product. Be sure to test your concrete for high moisture levels if mold is/could be a concern.

Radon seal has no "finish" after application. It soaks into the concrete. Read instructions on the can as to applying anything over it.

My purpose for purchasing this product was for a moisture barrier and cushioning. I used it over a concrete slab. Cannot speak to the sound proofing qualities. My floor was quiet to walk on and had just enough give to let me appreciate that it was wood and no longer vinyl over concrete. I would buy this product again.

It does not appear to be sealed. It has handled normal seaside moisture for over a year. Mine is mounted in a console and is not exposed to direct splashing

No ! It needs to bond to the surface of the concrete! Not ment to be applied over primed & painted concrete !

How long did you let concrete dry before putting down sealer? I would apply another coat, was the sealer new? I had a similar issue with old product.

Depending upon your application it will work as a moisture barrier you only need to use some type of sealing tape for the seams, duct tape or 3" package sealing tape works fine. If you have known moisture issues, you will need to use the more expensive self-sealing underlayment with built in vapor barrior. Your other option is to use 3ml visqueen between the concrete floor and this poly foam base. I hope this helps

I haven't really used it because it is in our downstairs unfinished basement. But it is truly marble and there is no documentation that the marble was sealed. So I plan to seal it before we use it. (but it came in perfect condition).

I read the same review you did, and if you notice, the smell didn't appear till after they pulled it up. It sounds like a case of moisture coming through the concrete and causing mold. This would have happened with any product. The underlayment did its job and blocked the moisture and smell from the living space. In my mind it is a case of "user confusion", not product failure.

This product works great on mold! Obviously you need to find the source of the mold, but the ozone feature kills mold, mildew & bacteria. My mold problem was so bad in the basement that we could smell it 2 floors up. There is no more mold growth & now the basement is the freshest room in the house - this product is worth every penny!!

This seal dries clear. You can paint over it. I used it to seal out moisture in my basement.

Agreed, mold can develop if you let it wet for too long. However, I do recommend this product. Have been using it for some months now and no complains.

C.C. Based on the amount of information you provided, its hard to say if this product will be what you need to treat. For example, if the wood floor is lying on top of a cement slab, you'll likely have to treat under the slab and not have to worry about the floor. But if the wood floor is over a basement, there could be a lot of entry points that might have to be treated so in the end, its just hard to say without seeing the structure, etc. At this time I believe it would be best to consider hiring a service company or at least have some look at the problem so you can learn more about whats involved, what will be needed to treat the problem, etc. In the end, it might end up being something you can handle but in many cases, hiring a service company is usually the best way to proceed when dealing with a termite problem.

I bought it for the cushioning but mostly for being a moisture barrier for a single story slab home . If you plan on installing your new flooring on a second story or higher, or on a pier and beam foundation, a lot depends on your sub floor. Call the company. It isn't labeled as a sound proofing product and there might be a better product for your purpose.

I purchased one for my parents home that at one time didn't have a vapor barrier under the subfloor and mold formed on the underside of the wooden floor. This in turn caused a moldy smell in the house at all times. But the green machine has eliminated that smell. Did it kill the mold under the subfloor? I doubt it, but no more moldy odor or health effects from it.

We rolled it out, let it acclimate and occasionally duct taped seams together underneath bamboo click flooring - we did not glue. Our floor has been installed for over 6 months and we've had no issues. LOVE having the cork underneath - it lessens the clicky sound and adds warmth to the room.

On top of any flat, level surface is perfect. Definitely no need to put anything down on the concrete. Mine is built directly on the ground, and the surface is level but not completely perfectly flat, and it fit together perfectly and the doors operate perfectly. It's not as fussy as some seem to indicate. Any concrete surface that's even close to flat will be just fine.
