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. ### ⭐⭐⭐⭐⭐ Great for parade floats, bins, and underlayment! *by on Reviewed in the United States January 17, 2026* 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. ### ⭐⭐⭐⭐ Worked as advertised *by on Reviewed in the United States February 28, 2023* 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. ## Frequently Bought Together - ROBERTS 50-040 Underlayment Tape Roll, Red - ROBERTS 70-115 Moisture Barricade Underlayment Film, for Vinyl, Laminate SPC, Engineered Wood Floors, 6 mil.
