Can this be used under a new concrete floor?

I put the wire on top of fully dried concrete and poured concrete on top to set it, then tiled over with slate. I'm sure you could do a full concrete floor instead of tile. It would likely be warmer without the extra layer. FYI--on my first order this vendor sent the wrong length of wire. I payed for the longest and was sent one much smaller. They shipped the correct replacement length, but I had to mail the wrong one back. Very inconvenient.

Yes. I buried mine in the thinset under my tiles.Works awesome. I wish i would have done it in my kitchen as well

No. Would not be a good idea to use this drill on concrete. There are special drills made just for that. This type of drill would burn up easily.

I have not used it on a floor , you might want to contact a wood floor installer with this question , just to be on the safe side.

Yes you can do that just make sure you clean the old floor good before installing the new one over it

definitely not. You need a hammer drill and hammer drill drill bits for concrete drilling

Not really. It would not touch on level concrete, but soft ground, high brush, etc it will touch.

On concrete you should not need the floor frame kit, or plywood. just a drill and a couple of concrete anchors. I bought the anchor kit and it was overkill, 4 anchors should be enough.

I would say yes, that this would provide some prevention against mold or anything like that. It's two layers of plastic and in between are zillions of little pieces of styrofoam. I would guess that nothing is perfect for below grade, but this seems like it would work. But I'm no flooring expert. :)

I would not try it. I used it mostly for the carpet. I never tried to use it for the concrete.

yes, if the radiant surface is not "too warm". They will also counter some of the radiant properties (similar to carpet) of the concrete floor, but I wouldn't fret too much about that.

I have not done this, but from my experience using it for wood, if the underlying surface is flat and smooth, then it should work.If the concrete has a rough or dimpled surface, then it will not work well at all. I would use a wire brush in that case.

I see no reason why you couldn't.. I would create a test "patch" and try it out. Might absorb differently than the existing concrete, so be aware of that. That would make the color a bit off. May need an extra coat, etc..

The concrete basement floor that I put it in on was pretty uneven and it worked great. If there was an ubrupt change in elevation or large gap, I could could see that being a problem. I wouldn't put any padding or pre-floor.

I did a large concrete floor with no problem. Took a day or two to stick well. I would have a two sided tape on hand for tiles you have to cut.Good luck

Haven't tried it yet, but if it works as well as it does on floor...should be no problem

Yes they work great on my concrete floor....I didn't use any installation and it's warm to feet no shoes needed.. ..hope that helps.

I really have no idea. It works great on everything I have found but a concrete floor may become to slippery perhaps. I myself would like an answer to that myself. good luck
