Can I install Dmx, then plywood and ceramic tile on top of it?

Asked by Alessio August 23, 2020
3
Answers

Yes, But...you need to fasten the subfloor to thru the DMX-1 to the floor beneath. I installed over concrete. I had to use 32 tap-con screws per 4 x 8 sheet with an ASTM sealant in each screw hole to prevent moisture from coming up thru the holes or down into the holes in the concrete. It was solid as a rock when complete.

The DMX is actually pretty stiff and the dimples are difficult to compress so a distributed load with a plywood layer 3/8” or better should not be any problem.

Can this product be used in Living room with concrete floor and high moisture?

Asked by Ramro June 12, 2020
3
Answers

Hello Ramro: DMX 1-Step Underlayment has been designed for concrete floor applications, i.e. basements or slab-on-grade. Our dimpled underlayment provides an air gap for moisture to evaporate. However, depending on the level of humidity, it may be recommended to have a dehumidifier in the finished area. Customer Care DMX

The installation guide says "Check the level of the floor with a draw string, it should not exceed a 3mm difference over 3m, or 1/8” over 10’." I would say if you have peaks or valleys outside of this range you may want to use floor leveler

How can I use my military Timberscent discount

Asked by Henry May 7, 2020
2
Answers

I don't know about a Timberscent discount, but there is a ten percent discount for military veterans. All you have to do is show them your dd214, a VA card or your Military ID Card. If you show anyone of these at Home Depot they will give you 10% off all your purchases. I'm a veteran and I use my picture ID that I got from the VA all the time.

My basement is aggregate concrete so small pebbles consistently protrude. Can this be installeinstalled o we aggregate?

Asked by Jetemy May 6, 2020

Answer

Hello Jeremy: We do not recommend installing DMX 1-Step directly on the aggregate. The aggregate could cause an uneven surface for the underlayment. DMX 1-Step is recommend to be installed on a flat surface that is level up to 1/8" over 10 ft., as per the flooring manufacturer's recommendations. Customer Care DMX

Should you usd landscaping fabric underneath or no?

Asked by Lukas May 2, 2020

Answers

I’m not sure why you would consider using any other material underneath the DMX. The 1-Step is a bi-layer polymer which deadens sound effective (white side) and supporting structural blue side is designed the allow concrete to breathe while stopping the moisture from entering the space above it. However, surface preparation is essential and is clearly recommended by the manufacturer and noted on their website. There are several videos on the internet which are also very helpful if you’re installing it yourself.

Works well, fairly easy to install
This underlayment does a decent job of keeping our laminate flooring warm and dry. It’s also very easy to cut to size with either a box cutter or scissors.

I have recently installed the DMX product. It is a saving using compared using other products. So far I am pleased with the product. I have layed down a OSB subfloor, which given a solid floor and increased R factor. I will write a review a year later for an accurate review
by Rokkie
Easy to use, Really great product
Finished a basement bedroom floor and chose the DMX 1-Step because it seemed like a great design to prevent moisture damage to floors and make the room quiet and warm feeling. Rolled it out on the level concrete floor, cut it at the walls, taped it as instructed, laid the laminate over top. Very fast, very easy process. Walking on floating laminate is quiet, soft and comfortable. The DMX 1-Step underlayment makes the room seem warmer too. Great product.
by Craig126
Great product
Easy to lay on the floor. Silent. Used in the basement on the slab and i feel it helped a bit with warmth but the floor is still on the cooler (as is the basement).
by James
Easy to use and lay. Instant comfort underfoot
So far so good with our install direct on 1950’s basement concrete floor. We have found this to be ways to work with (although it is annoying that it is rolled backwards for laying it out in a room). Easy to install and just under 4’ wide makes the rolls manageable.
by Shannon
Does wonders.
Easy to work with & does the job. Highly recommended.
by Larry
Easy to install
This was pretty easy to put down and made the floor warmer to walk on. Until we are sure the water issue we were having is resolved we just relaid the Berber carpet for the time being. The underlayment bubbled up in a few spots and clicks when walked on but I'm sure this will stop when we lay the floor. So far we are happy with the product.
by Red Robin
Worked well
Easy to put down in basement. We put laminate on top with no issues. Floor definitely feels warmer
by Christina
Incredible quality, excellent product.
An absolutely incredible product with extremely good insulation. Laid it flat on a concrete floor with 10mm TrafficMaster laminate floor and the difference from the concrete to the top of the underlay was unbelievable (yes... we tested). Lays and cuts easy and was a super fast and economical option that has fit all of our needs for the basement. We wish we had used it upstairs too!
by H Sutherland
