Customer Questions & Answers

does this underlayment need an additional vapor barrier over concrete subfloor?

No. A vapor barrier is built into the product.

Can I use this beneath a click lock bamboo floor?
Asked by: Sach
Yes, just be sure to staple it down if you can, if not it is okay as it has an adhesive on one side.

is this product suitable for regular hardwood nail down installation?

Asked by: Anonymous
That depends on whether the subfloor is concrete or wood. If the planks are nailed into the subfloor, it would puncture the underlayment, which would render its moisture barrier pointless.

We are purchasing laminate (12mm) with attached padding. However, we would like to lay an additional underlayment for acoustics. Will this product work?
Asked by: MR
Thank you for your inquiry. Black Jack is not designed to be used with flooring that has pre-attached padding. Always confirm with the flooring manufacturer if any additional underlayment or padding is recommended or warranted with performance of the floor.

Black Jack 100 sq. ft. 28 ft. x 43 in. x 2.5 mm Premium 2-in-1 Underlayment for Laminate and Engineered Wood Floors is rated 4.2 out of 5 by 88.

I did read the reviews, because I was trying to install laminate floors in my living room by myself for first time (I've never seen anyone do this job); I never imagined that it would be so easy, the final result this underlayment was the best choice: I saved a lot of money, was easy to lay down, easy to cut. I had no problem at all with the adhesive, it's actually very easy to handle, do it slowly at first until you get practice. Floor is quieter than it was with carpet. Now I decided to do the whole house. I love it.

I think this is the second best underlay available from THD, next to FloorMuffler, which is over double the price. It does tear easily. Just be sure to unroll it as needed (four foot underlayment, then four foot of floor covering), as apposed to rolling out over the entire subfloor then starting to lay your covering. I've even used it to deaden sound when building car interiors.

This one was surely the easiest to work with. It's light in weight at all, but the product seems to be tough and durable. It's a good pad and moister barrier for under wood floors and should last for many decades. I think this will do the job well, I am using it on my current floor project and I've liked it so far.

Rated 5 out of 5 by from Quality product I rehab houses and I install a lot of laminate flooring. Lately I've been using Robert's Back Jack and I'm pleased with the ease of installation, the moisture protection and the soft feel under foot. From experience let me make this suggestion. Like most underlayment I've used this will not stand-up to unprotected foot traffic, it will snag and tear easily, so install one row at a time, apply your flooring, then install the next row, this will minimize it's exposure. Also, remove all staples and fully seat all screws and nails into the subfloor. Like most things proper preparation is the key to perfect results.

Rated 4 out of 5 by from Great product, needs slight improvement This is a sponge neoprene underlayment and appears to be very well made. It comes with a plastic flap on one edge and adhesive tape on the other. The flap and tape are great for situations where you need a vapor barrier (such as over concrete) but it's handy to have regardless to keep your seams tight. There are a couple down sides though: 1) It comes rolled up the wrong way so that when you unroll it the up side is facing down. A minor problem but a bit of a pain. 2) It does not unroll in a nice straight line but rather a slightly curved arc. Don't try to straighten it out or you'll create puckers and bumps. Just go with the flow and be sure to allow about 2" of material to bend up the wall so you can trim it later. 3) Some rolls have splices in the material. Instead of butt joining the splices they overlapped them. I had to cut out all their splices so i could butt them properly. Even their instructions say not to lap the joints! 4) The paper backing on the adhesive tape can be a little difficult to remove. It takes some patience to get an edge started so you can strip it off to expose the sticky tape. Aside from the above, a great product that does what it's supposed to do.
