   I used 1/2" Denshield in a shower five years ago. No problems yet. Installation was easier than DuraRock.

   *I've used it in 1/2" on shower surrounds with great results. Much easier to work than cement board or DurRock. Didn't know it came in 1/4". What deoes the manufacturer say about use on a floor? I'd be inclined to underlay it with poly or tar paper.Clint Searl

   *I have a little over 300 ft of the 1/2" on my floor for over 4 years now. It's working great. Its the tile that hasn't performed so well.

   *I used it on two bathroom floors a couple of years ago. It is the only backer board the tile place sells and they insisted that it was fine. There have been no problems.Backer board is a frequently discussed subject on Breaktime, and Dens-Shield is frequently frowned upon for use on a floor. I have repeatedly asked if anyone has any negative experience with its use on a floor, but so far no one has offered any.On the other hand, I believe Rob is the first person to claim to have used it on a floor.This past summer I dropped a small piece in a bucket of water and let it be for a few weeks (this seems to be the preferred testing method for materials on Breaktime). It had the consistency of mush when I pulled it up. Whether this means anything or not, I don't know. In a proper installation, I suppose the edges are not so exposed.Next time I tile a wall, I will use it (it sure is great to work with!). I'm still thinking about the floor.Rich Beckman

   *Rich,The floor I used it on is the kitchen, laundry & full bath. One edge has remained exposed the entire time . This is in an entry stair that eventually i will get around to finishing. While your test might be applicable to a shower floor, I belive any other application would not be subjected to a simialr amount of water.

   *Rich, I'm surprised that your Dens-Shield turned to mush. I tried the same experiment and the stuff floated for two weeks with no noticeable changes. I wonder what's up with that? Different production runs?FWIW, the manufacturer says not to use a vapor barrier behind Dens-Shield, because Dens-Shield's face is also a vapor barrier. The two in combination apparantly can trap moisture, leading to I don't know what sort of disaster.Andy

   *LOL! If nothing else, you have supported my statement about the preferred method of testing!I think I left my piece in longer than two weeks, but I didn't keep track. Not really thinking of it as science. My piece was to big to float, so it was underwater, and it was ourside. Also, prior to throwing it in the bucket, I parked the car's right front tire on top of it a couple of times overnight (which didn't seem to have any effect on it at all!)Rich Beckman

   *Say for you folks who have used this stuff what do you use to tape the joints and water proof the ends say where the denshield meets the tub on a wall surround installation ?

   Just bought some 1/4 inch dens-shield ceramic tile backer board to use in a bathroom remodel over a 3/4" plywood subfloor above grade. Kind of nervous to try a new product and was wondering if anyone has tried this material and how did it work out for them. Seems like a great alternative to cement board, not nearly as heavy, etc. How does this compare to hardi-backer?
