Questions & Answers

Can you use this over old vinyl flooring then new laminate floor? No plan to take old vinyl floor due to asbestos in it.

Asked by: Ja
My experience with this product has been very good. My application involved laying product on slab floor then covering with 1/4" exterior grade plywood then vinyl sheet on top of that. I think that as long as your base vinyl is flat and not too soft this product should work great. You may want to consider tacking it down with patches of sheet glue to keep this underlayment from lifting off of existing vinyl substrate. Good luck!

Can this be used with engineered wood over plywood sub floor on second floor?

Asked by: Ant
You can but it would be a waste of time and money, it’s meant to be used over concrete flooring to allow for air movement

Can you lay carpet on top of this?

Asked by: MAnt
No, i didn't use this air gap underlayment under the carpet. I have used this item under subfloor, so there will be no cold air, no cold floor, no insects, and it's doing real good.

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 104.

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.

It takes some time before I can say that wetness is not accumulated underneath the liner and i don't detect the smell of mold. I wish it would be sold as a 50ft option. I needed only 144sq ft but I had to buy 200.

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
