Questions & Answers

Can this be used with just laminate flooring over a cement floor in the basement?

I have a basement I am finishing with a cement floor. I want to use laminate flooring. Can I use just this subfloor to waterproof or will I need additional waterproofing? Basement is just damp and doesn't flood at all

Can I install vinyl planks 4.2mm thick over this?

I have to install vinyl planks over concrete. The concrete has some cracks that I want to fill first and then I was thinking of having a subfloor to help with the floor being cold. Recommendations? Also can I install the 4.2mm vinyl planks right on top of this product?
Asked by: JPcarp
Sorry i don't have a definitive answer. I would say check YOUTUBE. I believe it said that the flooring that is installed over the DMX should be no less than 7 MM. I can't be positive but that's what I though I heard. They have some good info on this product at YOUTUBE and it would be really good over the concrete. When walking on the floor with the DMX under it you would never think you are walking on a concrete base. The installers who installed my floor never had seen this product but were very impressed.

Asked by: Dave
According to the website, the product is 5/16 inch or 0.3125 inches, so less than a third of an inch. Trust manufacturer specs vs retailers specs.

what kind of tape do you join the underlayment strips to each other? what brand? what kinds of flooring will go right over it for utility room?

Asked by: boocatsdad
For our DMX-1 underlayment we used their recommended Indoor 2.5 in. x 80 ft. Clear Vapor Tape. We used two boxes of DMX-1 and ordered 2 rolls or tape. This we just enough to complete the job.

This was not the correct product, however I was able to order the correct one from DMX AIRFLOW website. The two products lay the same and was very easy to do. I did a successful moisture test on the product giving it 4 out 5. Product name (DMXAIRFLOW). HomeDepot only carries Dmx step 1 not to be confused with DMXAIRFLOW.

We had been going back and forth between this and the dricore. At the time, decision was for quicker installation and price. VERY glad we went with DMX. The basement has only had water come up from the floor a time or two in last 10 years. A week after we had finished the remodel, had an unusually heavy rain and water came up. The DMX performed EXACTLY as intended/stated. It kept the laminate flooring safe and dry and channeled the water to the edge. We were so impressed. A couple of recommendations/hints: - Do unroll and let rest for a day, if possible. Makes it much easier to lay and tape together. - If possible, leave the lowest end/side open so water can drain out, if it gets to that point. - Try to use as few pieces as possible. It is a little harder, than standard underlayment, to tape small pieces together.

Rated 5 out of 5 by from I was installing a click lock system vinyl plank flooring in my basement and wanted a sub floor s... I was installing a click lock system vinyl plank flooring in my basement and wanted a sub floor since my child and her friends will be hanging there. Knowing a sub floor over a concrete floor is the difference between a bruise and a break (and doubles as an extra insulation barrier) I needed something that would resist mold and mildew. My basement floor will (rarely) get moist, but never wet (flood) so mold and mildew were a major concern. After MUCH research, going to stores and hours of watching videos on many products, I decided on DMX 1STEP. I tried to level the floor as best as I could according to the directions on line (not being off more then 1/4 inch in a 4' area), but after pouring almost 5 bags of self leveling cement I laid my 8 foot level and noted the floor was uneven by 1/8 to 1/4 inch in various areas like a roller coaster. I bought another 5 bags and when all was set, noted the same thing, but now in different areas- so feeling it would never be 'perfect' I threw caution to the wind and just laid down the DMX 1-step, considering both the DMX and Vinyl floor are flexible. THRILLED, THRILLED, THRILLED, is all I can say- It went down beautifully, and was a wonderful sub floor for the plank click system flooring that floats on top (also purchased at HD). After laying the DMX I also immediately felt a warmth difference in the room which was wonderful! After the vinyl floor was installed you can feel a bit of nice give to it, nothing you would notice unless you were actually looking for it, which I was by jumping on it and hoping back and fourth. I would highly recommend this product to anyone looking for a sub floor (esp. in their basement). I also noticed it is soundless (no clicking when walked upon) an added bonus. I did buy the TYVEK barrier tape to hold it together though, not the recommended DMX tape, an oversight when I ordered it. The tyveck tape was SUPER adhesive and did the job well so unfortunately I do not have a review for the DMX tape, but I am sure if its as good as their sub floor it will be just as adhesive and you can save a few dollars buying it when you buy the sub floor.

Picked this product primarily for its thinness (3/8") vs other basement flooring systems (low ceilings). Easy to lay down and cut. Lays flat even though it's rolled up fairly tightly. It's soft (think foam) not hard plastic so it does get damaged if materials are dropped on it.

Finishing Maine vacation home basement. 4 rolls so far with 5/8 plywood over for better R/comfort, and then a good quality wood laminate. The rolls are very easy (lay and tape), and surprisingly strong to walk on. Value/integrity looks much better than Drycore product. Pleased so far
