We just laid 1100 square feet on LVP and used this as our underlayment. Only 2 rooms had cement floors after tearing out the carpet, the rest was floated over linoleum. According to both the package and the website, a vapor barrier was not required underneath. This underlayment was fairly easy to lay down. We just drug the length out and cut it at the wall with a box cutter. In areas where I had to piece pieces in we used underlayment tape to tape it together, but you can also use packaging tape for that. Keep a broom handy to keep it clean before you put flooring on top of it. At first, the floors had a little bit of a clicking sound as you walked, but after 2 days that went away as the floor settled in. Our floors are quiet and have a very soft feel to them when you walk on them. This underlayment did exactly what I wanted, it was perfect. Not to mention it was also less than half the price of what you would pay at the big box store. I ordered two rolls of 600 ft and had plenty left over. ... show more

    • This is a great underlayment for flooring
Size Name: 100 sq. ft.
Absolutly, loved this underlayment. It was easy to put down, and it is just the right thickness. I would definately recomment it. It is priced right, and is good value for the money. My husband laid the flooring (click clack) on top of it an there was a small dip in the floor before he laid it, in one area, and you don't even feel it. The flooring feels even and comfortable to walk on. It is durable to walk across as well before putting down the flooring without tearing up. The measurents for the product are accurate, and it functions as descriped. ... show more

    • Nice underlayment, soft feel
Size Name: 100 sq. ft.
I used this underneath vinyl click-lock tiles because the bare surface was uneven due to some leftover glue on the floor from the old vinyl sheet flooring. It's a little soft which kind of bugs me, I can definitely feel some give every time I walk on it. I think if this was used underneath laminate or any thicker floor it would work perfectly. My tiles were only 4mm. Can't knock it too much though, I think any foam underlayment is going to be a bit soft. Although I bought some really nice Pergo Gold from Lowe's for my main level using 12mm laminate, and that seemed a bit more firm. It was also 3x the price, but it did come folded rather than rolled which was awesome. This is a nice product though, rolls out flat. Easy to damage from walking on it though so be careful. ... show more

    • Floating floor underlayment
Size Name: 600 sq. ft.
Used to give extra padding to to a floating floor and to help level out certain areas of the subfloor. Worked real well but seems to be rolled backwards.

    • Fantastic Padding for Engineered Hardwood Flooring
Size Name: 100 sq. ft.
This Black Jack padding is no joke!!! I had tried a different brand, blue-colored 3mm padding and that stuff was a pain to install and it just felt cheap. The blue padding went down okay, but after I installed my engineered hardwood flooring over it, I did not like the sound at all. I used this Black Jack padding under the same engineered hardwood flooring in my downstairs area. Although it is only 2.5mm padding, I love the quality of feel to the touch and the quality I felt as I was installing it. When I walk on my new hardwood flooring, I love the sound!! I HIGHLY RECOMMEND THIS PRODUCT!! It's relatively inexpensive and worth every penny. When I end up doing more flooring, I will use this product again. ... show more

    • Best purchase. I’ve never laid hardwood floors myself before and it was so easy to use.
Size Name: 600 sq. ft.
I love it. It’s cushioned and makes the cement floors under the wood better to walk on.

    • BUY this not the Other
Size Name: 100 sq. ft.
Lets start off by saying all the negative whiners on here reviewing poorly, I don't know what the heck you all are doing buy you are not doing it right. I'm not a Pro, I'm an IT guy, laid several rooms of flooring before this Bought the Big famous Blue pads before on amazon, took a chance on this because it looked interesting. The only this is it rolls on what i would call backwards. Its all explained in instructions, feels like the factory might need to reverse their rolling. I prefer to unroll list most people drop the edge and kick the roll across the floor, this is a bit different process, but it wasn't bad, just need to be aware is all. I had no problems with tearing and flimsy as others are reporting, I walked on mine and crawled on floor with knee pads as well, no issues with tearing at all, all cut fine and seemed like high quality to me. Great pad, works well, no issue on install, think some others are negative type of reviewers Worth it all, shipping was good too ... show more

    • Good stuff
Size Name: 100 sq. ft.
Fairly easy to put down, as good or better than what you’ll get a big box stores, but half the price. Had down for several weeks before I finished laying the flooring down and it help up really well. It’s foam, so you can’t drag stuff over it, but walking on it isn’t enough to do any real damage, and the fact that it’s black makes any dirt/debris easy to see when you’re cleaning it up before laying down flooring. ... show more
