G-Tape’s 3040BK Black has quickly become a favorite of deck builders across the United States. No other product combines performance and ease of use as well as adds protection to deck joists and helps increase longevity. The G-Tape 3040BK Series provides the ultimate flashing performance with unmatched contractor friendly features. The AAMA 7-11 Level 3 Class A rating means the 3040BK tape meets the highest standards for hot and cold performance and does so without the need for any additional primer. It is lighter weight than butyl or rubberized asphalt flashings and outperforms these products by significant margins. Although the tape is permanent, it can be removed from face to face adhesive contact cleanly with no loss of performance during the application (meaning, if you accidentally fold a piece onto itself while removing the backer, you can still peel it apart).
