Questions & Answers

Do I need the underpayment if I install vinyl floor in the basement?

Asked by: Katrina
After reading tremendous articles about basement. I would suggest you purchase a underlayment. Your basement has a cement floor which is very porous. With that being said the moisture from the soil will breathe through your cement and will create mold if you don't let it breathe and give it space to dry. What the underlayment allows is that moisture to escape and dry underneath your floor. I use this DMX product in my basement. I can't tell you its the best thing yet because I just installed it about a month ago and won't know the long term advantages until about a year a two and really figure it out. But with all the reading I did, this is the route I chose. Good Luck

I know this is far from the intended use BUT can I use this on concrete patio under an outdoor rug to prevent mold etc?

Asked by: Kate
Im not entirely sure, however, I will say that i put this down on my concrete basement floor and before i was able to put the flooring down on top of this I ended up getting a bit of water in my basement. This was the first time i ever had water in the basement and it wasn't much, but i soaked it up, and ran a dehumidifier. I then put the underlayment back down and within two days had mold growth underneath it. My basement is not yet finished, and i don't have the walls up, so airflow was not an issue. I am not convinced that this product does what it says it does. As a further precaution i painted the concrete with a mold barrier paint purchased from the home depot, and even with that and the DMX on the floor i had small areas of mold growth. I am actually kind of disappointed as this stuff isn't cheap.

How does this material allow water to evaporate if it is water-proof on both sides? Would it not just trap water?

Asked by: Katie
This material lets air circulate beneath the floor level to allow concrete and the earth below it to interact as it normally does in construction. It is probably not suitable if there is active water involved or very damp locations. It makes a great underlayment on concrete floors. Helps add a soft feel to the installed flooring.

My basement floor is cold. Does it help to make the warm?

Asked by: Katrina2018
Yes: This product helps somewhat with minimizing a cold floor radiant in preventing direct contact with the sub floor and the top flooring, but that's not the main function of this product.

100 sq. ft. 3.67 ft. x 27 ft. 6 in. Unique Air Gap Underlayment Prevents Mold and Mildew is rated 4.5 out of 5 by 132.
Rated 5 out of 5 by from The BEST way to control moisture and give your floor a softer feel! I bumped into this product searching the Internet for a way to waterproof my basement floor. I emailed several questions directly to the manufacturer and they responded immediately with details on how to handle each situation. DMX 1 Step is easy to install and as I covered more of the concrete floor I started to notice that musty basement smell could not be detected in the areas I completed. The hardest part for me was drilling into the concrete floor to use the TAPCON screws. Buy a higher quality hammer drill and lots of drill bits. I installed 5/4 x 4 sleepers and then 3/4" OSB glued and screwed over top. The sleepers are installed 24" on center. The floor has the same kind of flex as the main level of the house. My wife loves the way it feels when she walks on the basement floor. The moisture control is allowing us to install hardwood floor in the basement. That is typically a no-no. I'm confident the DMX 1 Step is going to be the key to my finished basement not looking or feeling like a finished basement. It's a great product!

I am installing 3/4" plywood over DMX 1 Step on a concrete slab and finishing it off with Lifeproof laminate flooring from Home Depot. I think anyone with basic skills can install this product. It is soft and flexible, yet durable and cuts easily with razor knife or scissors. I am already noticing a big difference as far as floor warmth. I am using Tapcon screws to fasten plywood down to concrete and had a problem with the screws not holding, after consulting with Tapcon tech support, they determined that I was using too long of a screw and recommended using 2 1/4" screws for my application and using a countersink drill bit. After I followed their recommendations, I had no problems. I see no downside to using DMX 1 Step and will definitely recommend it to anyone. The vapor tape was they sell for DMX is expensive at about $10.00 per roll, each roll only covers 100 square feet. It looks like clear packaging tape to me so, do some research on the tape, you might save some money using packaging tape instead. Overall, great product. I'm glad I chose DMX 1 Step.

Rated 1 out of 5 by from Noisy Creeking I purchased this product to lay a laminate in my basement. Did quite a bit of research and decided to be cheap and get this and not Osb subfloor. After installation, it is creeking extremely loudly at each step. I called and asked DMx for help, they said I should pull up the floor and relevel. I explained that I had already used concrete to level the floor. I wish I wouldn't have been cheap and would have bought the osb subfloor and not dmx 1 step!

Rated 5 out of 5 by from DMX 1-Step = a great choice My wife and I hired a general contractor to finish our unfinshed basement in our newly built home. In order to save money I decided that I would handle the subfloor and floor installation in order to save labour costs and we would leave all the rest (framing, electrical, plumbing, drywall etc) to the pros. We spent a few weeks going back and forth between DriCore and DMX 1-step for our subfloor. After many trips to Home Depot and lots of online research we chose to go with DMX 1-step, and I am so glad we did. Not only is this product the best cost/sq foot in subflooring it is by far the easiest to install! Aside from the easy installation I think the number 1 selling pioint of this product, (aside from all of its great properties) is that there is almost NO WASTE when installing. Every scrap piece of DMX 1-step that I had left over from cuts I was able to use in a differnt area. We had a few tricky angles from the overall design and yet all I needed to install this subfloor was an exacto knife. I installed 12mm laminate flooring on top of the DMX and we could not be happier with the look and feel of our new basement floor. Thanks DMX!!

Very good product, effective at getting the awful vapor odor coming through the concrete floor in my outbuilding under control so far (have had it installed 3 weeks or so)and is a sturdy underlayment with a soft feel. Easy to work with, even without any experience. I will definitely be purchasing more when I do my basement floors in the future.

Rated 5 out of 5 by from Great product When I decided to finish my basement, flooring was a tough decision. I ended up putting in eng. hardwood floating floor. When it came to the underlayment I did a ton of research before making this purchase. Honestly this was the only product that covered all my needs. 1. Need to cover cold concrete basement floor in Michigan 2. wanted some R value 3. Didn't want to break the bank 4. Easy install 5. quiet Heres what I found with DMX 1. Got the R-value I was looking for, I installed in the winter and it was amazing how much more comfortable the room was once the underlayment was installed. 2. It cost me 1000 bucks to get the large area covered, but compare that to some of the other products out there and I would have spent 5k on underlayment 3. super easy to install 4. After it was done I was amazed at how quiet the floor was. I read a lot of other reviews with other products that had a click to them when installed on concrete. Bottomline - buy it, you wont be disappointed. Also, look up DMX on youtube they have some great info on the product there.

The DMX product is a little thicker than I expected and I don't recall its thickness ever being mentioned. I will have to use transition strips to handle the floor height differences.
