Rated 4.4 out of 5 by 19 reviewers.
Rated 3 out of 5 by Short sized I was very disappointed with the sizing. The poly sheets (2) were ordered as 10'x12' but arrived as a 9'6"x 11'-10" . The fact that it was 6" short didn't allow for the manufacturer's required overlap of 8" in my 20' long room. there's just NO excuse for the product to be undersized. Other than being cut undersized........ it's a reasonable product. April 22, 2014
Rated 3 out of 5 by Price is fair for the product...but size is nearly 3 inches short. While the thickness is adequate and as good as it gets for a moderate moisture barrier... The added antibacterial/antifungal feature should prove to help in reducing if not eliminating mold that can develop on concrete floors especially below grade. My complaint is regarding overall dimensions, the packaging and handling of the plastic at the factory. This item is not carried in the store so its impossible to hand select the best product from the shelf and leaves you up to the discretion of the picker in the warehouse. So, when I unwrapped the vinyl the first thing I noted was the odd way it was folded and rolled leaving weird creases in the vinyl. As I laid it out in a room that measured less than 9 X12 feet, I was surprised to find the length almost 3 inches short of the 12 feet listed as the minimum dimension on the product. I honestly expected the sheet to be a scant OVERSIZED rather than UNDER. It makes it difficult to overlap the sides of the room without patching... which is why I order the 10 x 12 sheet rather than a 3 foot roll. October 26, 2013
Rated 5 out of 5 by Great for laminate floor installation on smooth concrete slab. Used this vapor barrier on my Allure Traffic Master laminate flooring installation. This was put on top of the relatively smooth concrete slab with an 8" overlap when taping pieces together. Then a SimpleSolutionsSoundbloc Foam Underlayment for Laminate Flooring was used on top of it for comfort and flooring sound reduction. Worked great. Was able to install this vapor barrier by myself with little to no problems. Better to install this than to have moisture set in later down the road causing mold and mildew issues. Thus damaging your flooring and affecting your health. Ensure concrete slab is smooth and free from debris prior to installation. October 31, 2012
Rated 4 out of 5 by Great Product, great price I was looking at all the other rolls of plastic for the project I have and the price's were rather high. When I found this underlayment it was perfect for my needs. I'm using it under my indoor plants that are in 5-gallon buckets and are heavily watered. Of course that kind of watering means lots of run-off and inside that's a big problem. So I doubled half this roll under my 16, 5-gallon buckets and I no longer have to worry about my carpet being wet or stained no mater how much watering I do. This was the perfect solution for me.

Rated 5 out of 5 by Very easy to use and more than adequate for it's purpose. Needed more than I ordered. I forgot about the 8" overlap for each piece January 28, 2014
