Rated 4 out of 5 by from Good stuff, saves money This product is a must for finishing a concrete floor in a basement. It gives the concrete an air gap so any moisture that seeps through can dissipate. It acts as a vapour barrier to help prevent warm, moist air from touching the cool concrete and condensing there. And, it acts as a thermal break so that heat in the room isn't sucked into the concrete. For large areas, this product plus some nice 5/8 or 3/4 tongue and groove plywood will be more cost-effective than using those 2x2' subfloor panels. And, it is far better at preventing moisture exchange than those panels. You can find instructions on how to use this underlayment on youtube. Some videos will have you put screws through the plywood and into the concrete to hold everything down. That is what I did, as I found that imperfections in the concrete allowed the floors to float a little in places, so you'd hear a clicking noise when walking on them. You can put a little squirt of silicone in each drilled hole to keep everything sealed up. This underlayment just easily with a knife or heavy scissors, and goes down very quickly especially with a helper.

Rated 1 out of 5 by from Smells Like Recycled Detergent Bottles!!! I bought this product to use as a subfloor for my basement because it seemed like a cheaper alternative relative to other products. But my gosh was I in for a surprise... First of all the packaging was all chewed up when I got it, the photo I took is how it looked like when it arrived. Not to mention that it smells like old washing detergent bottles!!! I bought this product ONLY because it said it had NO TOXICITY/ODOURS... how can a company ethically say that this is the case when it has a horrible stench coming off of it...I am very disappointed, I have already processed the return! Very disappointed in HD as well... I am a frequent shopper here, and I am starting to question some of these budget products they carry..

Rated 5 out of 5 by from Excellent Buy for a Good Price Product exceeds expectations. I used this over vapor barrier on a gravel floor in my crawlspace. Temporary fix until I can get cement poured. It's made such a huge difference, and it looks great as well. The crawlspace is significantly dryer and feels cleaner too.

Rated 2 out of 5 by from very noisy it does fit together to overlap but when walking on, it's very noisy. I wish we didn't use this at all.

Rated 5 out of 5 by from Cheaper Than Competition and Easy to Install Easy to install and helps separate the floor from the concrete in our basement. Time will tell how well it does for humidity protection etc. Big bonus is its cheaper than the Step 1 DMX product for more square feet.

Can this be used as a vapor barrier with drainage for undisturbed soil UNDER 4 inches of solid foam insulation and a 4 inch pour of concrete? I have dug out an old basement and do not want to dig another six inches and then backfill it with gravel.

Asked by: Robert
I think so, I believe this material was developed as the vapor barrier for the concrete wall. B

Can you lay a luxury vinyl plank (wide plank with build in underlay) directly on this product, or do you need a layer of OSB?

Asked by: Mike
Yes you can but it's very loud. Especially if the ground isn't level.

can you use this on a concrete basement floor with rigid insulation on top and click vinyl flooring . without osb or plywood? and can walls be built on this.

Asked by: poorman
We recommend OSB on top of the DamPro before you install any floor. It helps to improve stability and noise reduction.

In the description, it says 200 sqft Later it says max 400 sqft. Is there 2 sheets in the package?

Asked by: Jack
I had 200 sq. ft. in my order. Works fantastic on a floor covered in at LEAST 12mm laminate. I used Red Tuck Tape to join the lengths together. @nd time we had used this product for basements. Enjoy and stay safe!

How thick or high is this product when laid down? 0.5 inches?

Asked by: Edward
Closer to 1/4. I ended up using a thin layer of vinyl cement. Otherwise it was noisy under 3/4” plywood.

Can this be used on basement concrete floor and just add carpet plus underpad on top, without putting any wood on top. 

Asked by: Curly
I do not recommend it - dimples are a bit big. I glued it down to keep it quiet, then foam, 5/8 plywood and laminate on top. Could possibly use 1/4 meranti.

What is the recommended thickness of OSB to go over this product to create a subfloor?  Is there an installation manual for this product?  Thanks 

Asked by: Reno
I’m not sure. I ordered 4 rolls of the underlayment & have been waiting for over a month for the 4th roll to be delivered. If it ever arrives, I will certainly share the results of my install.

Installing this throughout my basement with 5/8 plywood or osb. Can I screw this down heavily, add decoupling membrane, and then tile on top?

Asked by: Mrak
OSB on the top of Dampro and this can be screwed. Then your floor. You may add decoupling mat on the top of OSB or concrete if you install tile.
