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).
