Questions & Answers
59Questions20Answers
Would this product work on a wood plank basement floor. It's an old house an there is no Concrete.
Asked by Hauntedhouse June 21, 20211
AnswerI believe you can use this on pretty much any subfloor material, provided it's structurally sound.
Can this be laid over a rough concrete floor?
Asked by sally June 1, 20212
AnswersI don't see why not. I put it over an uneven wood floor and the thin cheap-o laminate flooring I put over it is nice and solid and smooth.
If I'm using vinyl planks with 6.5mm, do I still need plywood on top of this underlayment?
Asked by Marilyn April 18, 20212
AnswersNo. You can put the vinyl planks directly on top of this underlayment. The DMX Installation guide indicates any vinyl plank over 5mm in thickness can go directly over the underlayment. I have 6.5mm directly on top of it, and it's working well.
can I use this underlayment with 2.5mm thick vinyl planks
Asked by helloThere April 8, 20213
AnswersNo. DMX install specs call for planks 5.5mm or thicker.
Can you install LVP right on top ?
Asked by tom March 26, 20213
AnswersYes. The LVP goes directly on top. We have DMX in the basement under our LVP and love it.
If I use this product across the whole basement floor can I then build internal stud walls direct...
Asked by Ton March 19, 20212
AnswersNo, not a good idea. You need to allow 1/4 in gap between the DMX & the wall, then shoe molding should also have a gap of 1.5-3 mm above the LVP planks. That way air can circulate to carry away the moisture buildup
Leveling compound will not adhere to my concrete slab, so I would like to know if it can be appli...
Asked by Rick March 10, 20212
AnswersThis wasn't designed to hold leveler into place. The leveling solution needs to come from a different angle.
Can this be used under base cabinets that are attached to the wall? This is for a wet bar setup ...
Asked by Efloor March 5, 20212
AnswersI would not set your cabinets in contact with the concrete slab, obviously. I'm not sure of the structural/compressive strength properties of DMX, but does give a slight thermal break and it is waterproof. Since cold surfaces will condense vapor in the air, keeping your cabinets warm is critical too. So I'd lean toward putting a thermal/water control layer under the cabinets.
could this be installed over foam insulation board depending on install? for instance over a slee...
Asked by LTM March 4, 20212
AnswersNot a good idea, then the floor will have some give to it. This will destroy your LVP joints from the stress due to walking on top of it.
Can electric radiant heat pads be used with this product?
Asked by Diyordie March 2, 20211
AnswerHello: Radiant or electric heating systems can be used with our underlayment, as long as it has a protective felt or fabric. We do recommend to confirm this with the manufacturer of the heated floor system beforehand. Customer Care DMX

We installed dmx 1-step in area of 700 sqf in our basement with lifeproof vinyl floor and turned out awesome. Installing Dmx underlayment was pretty easy. We checked the level of our concrete floor before hand and everything was level! It’s been 3 months since we installed it and no problems so far. We are very happy with it! Floor feels warmer and also gives an extra cushion underneath the feet.

No more moisture and cold!
Finally a product that works! I installed DMX 1-Step 2.0 with Lifeproof vinyl 6.5mm in my basement. I bought this underlayment because the HD associate recommended it, and he told me that the air gap will evaporate moisture coming though my slab. I have always had a lot of moisture coming through the slab since we bought the house, and I have tried everything from the basic poly underlayment, to the dricore 2 by 2 panels, but they never lasted!
With 1-Step 2.0, the install is now done, and I am so happy, because I immediately feel a difference in the warmth of the floors. Not to mention that is also quite pleasant to walk on. My kids typically wouldn't to play in the basement in the past because of the cold, but seeing them run around the basement without even wearing socks made the whole install worth it! I will update if anything changes, but based on how the product felt in my hands, and insight from the HD associate, I don't imagine that the underlayment will have issues down the line. Highly recommend!
