Featuring strong adhesive and moisture resistance, it prevents moisture damage while ensuring long-lasting, tight seams.

## Description

ROBERTS Underlayment Seam Tape is ideal to join underlayment and carpet padding seams during the installation of floating flooring applications. Manufactured with a strong adhesive, this PVC-based tape ensures tight seams that hold for longer-lasting flooring installation. It is moisture-resistant to better protect flooring from moisture damage, ribbed for easier tearing, and thin enough so it doesn't add height to the underlayment. Versatile, this tape can be used for general repairs, sealing boxes, and other household tasks.

Review: Great for parade floats, bins, and underlayment! - 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.
Review: Perfect tape - 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.
