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 and other household tasks.
