The 2 in. x 150 ft. Cement Board Drywall Joint Tape has been enhanced with improved tackiness for added strength. It can be effectively used to seam various types of cement backer board and tile underlayment. The inclusion of fiberglass mesh provides even more reinforcement. The 2 in. width ensures a smooth surface for applying mortar, thinset or mastic, while the self-adhesive tape greatly reduces taping time. This tape is resistant to tears and will not shrink, making it a reliable choice for any project.
