Customer Questions & Answers

do i lay the foam with the tape against the wall or the foam or does it matter

Asked by: Anonymous
lay the tape side to adhere to the next piece, that way you don't have to try to slip the next piece underneath the first one.

The pad itself can get easily broken when being installed. I would suggest a 6mm poly film. It only costs $6 for 300 sq ft at lumber liquidator.

100 sq. ft. Unison Premium 2-in-1 Underlayment is rated 4.5 out of 5 by 113.
Rated 5 out of 5 by from Great Price, Good Product Why pay more for gimics? This stuff worked great, helped to dampen the sound and gave noticable cusion. Its actually pretty tough stuff. The trick to not getting rips is to lay the underlayment as you go. Unroll a strip of underlayment, then the floor till your almost to the edge, then unroll another strip of foam, work some more floor. That way you don't damage it when your trying to get traction when pushing the flooring together. I see photos of people who lay all their underlayment down first and then complain about it ripping when they are installing the flooring. Hope this helps someone.

This underlay is a must, unless it is a straight glue down. Under-lay vs Glue down: I find with the underlayment that the floor has a better feel and the "acclimation" process is just better. Straight glue down is cold and hard and really does suck, in my opinion! I believe most warranties require underlayment and for good reason I may add...

Rated 5 out of 5 by from Underlayment at the right price and quality I used this underlayment in conjunction with black 6 mil moisture barrier, for laminate flooring. Roberts under-layment does provide 2 mil moisture barrier which should be adequate for most non concrete sub floor app- lications. My kids enjoyed laying the underlayment. The finished floor feels and sounds nice. I would suggest buying some regular duct tape as well. It is rather easy while installing your laminate to inadvertently scratch and puncture your underlayment.

Rated 5 out of 5 by from Good Deal I recently put laminate flooring in my entire house and I used this underlayment in the bedrooms and dining room. I used the more expensive black jack product in the heavy traffic areas including the living room and I hallways. I can't tell a difference when it comes to the level of noise or cushion. I regret paying the extra money on the more expenisve product and I'm definitely glad I didn't do my entire home with it. The more expensive products are not worth the extra money you pay. I know from experience.

Rated 5 out of 5 by from GREAT VALUE!!! I just installed this underlayment in my front bedroom and had no problems. This is a very good product and a great value. It went down with no problems. The seams sealed perfectly to form a nice seal over the entire floor. I would highly recommend this product and plan to use it again in the near future. I see absolutely no reason to spend a huge amount of money for an underlayment and this product proves my point.

Rated 5 out of 5 by from Worked great! I have now used this product to install Home Legend click lock wood flooring in 4 large rooms, in two different homes, and it has exceeded my expectations. The product stuck together well, provided a sound layer between the existing floors and newly installed ones, and was economical to boot. Overall great product! Also, the Home Legend wood is fantastic! Beautiful and installs easily.
