Roberts 50-040 Underlayment Seam Tape 100 ft. Red

This tape work perfectly for securing different pieces of underlayment together. It also worked on securing starter and side pieces to the cement substrate so it doesn't move around during flooring installation. Easy to cut with scissors or tear by hand if you prefer. Tape is nicely thin, so the floor going over it doesn't know it is there. Had all the strength I needed. I am very happy with this tape and recommend it.

This is a great all-around tape for marking bins, wrapping up bundles, attaching plastic tablecloths to holiday parade floats as side skirts, and it tapes underlayment pretty well too.

Held down the underpayment. Allowed us to install the floor over the fully covered subfloor ans the tape held the underlayment perfectly in place. Easy to use. Effective.

Strong tape that adhered very well to my underlayment. The tape made tight seams that held up well during flooring installation. The only issue I noticed is that it is not forgiving and does not like to be reseated. If you miss your seam and need to pull it up a bit to reposition it, you may as well cut the tape there and apply a new piece because the adhesion wears off once it is removed. A small issue that hardly impacts it's usability but worth noting. I really like this tape and have used about 10 rolls so far.

Very strong hold with this tape. It is pretty thin so goes a long ways. Would buy again

This stuff is great. Easy to cut and holds up really well!

Cheaper and better than the stuff at home depot

Good when it's fresh. But it gets brittle as it ages, so buy it fresh and don't let it sit in storage for an extended period. And absolutely never use this on ducts. It's not nearly good enough for that. I bought 6 rolls of this tape. The first was crummy. It shredded when I tried to unroll it, it tore easily, and it was so brittle that it snapped if I pulled hard on it. And it didn't stick all that well. The second roll was much better; it was stretchy and didn't shred. Even so, the adhesive is only fair; it sticks adequately but not strongly to rolls of underlayment. I compared the two rolls and realized that the crummy roll was older. This tape apparently doesn't age well.

Great barrier. Has flex and stretch like painters tape. Anti mold properties. All round great product. Highly recommend. ⭐⭐⭐⭐⭐⭐. They also have premium underlayment. Check it out ✅

Great seal.
