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).

Great tape, sticks very well. Very comparable to zip tape. Would buy again as flashing tape

I saw this joist tape recommended online by a high-end deck designer. We built our own deck and decided the added cost of taping the beams & joists was worth it to protect from water damage/rot over the years. It also came in handy as part of our flashing design. Easy to work with, durable and respected by industry professionals - we are very happy with our purchase!

With no way of knowing how different types of deck tape will hold up over time, nor how well they will seal around screws, I'm basing this off of the installation ease. Simply put, this tape is so much better than other deck tape I've used. I was able to install myself with ease. It is very thin but definitely repels water. It is smooth and allows for composite planks to slide easily on joists. The fact that you can tear it off by hand into perfectly squared off pieces is awesome. The other deck tape I used (which was about 15% cheaper) is a massive pain to install. Furthermore, it start to lift off the joists in hours. After about 3 days I'm wondering why I even bothered. The G Tape does not lift off. Fantastic product.

Needed another roll after a making a large order from g tape direct to get free shipping. I mistakenly thought this was the same 3035 linerless tape. Turned out not to be a big deal. Liner was very easy to deal with and tape seemed to have better adhesion and felt a bit thicker than 3035. I like the dimensions of g tape better than box store brands as it allows for joist overhang and a bit of error while applying. Highly recommend.UPDATE: Second purchase I’m not sure what’s going on. Liner would not separate from tape properly, constantly ripping diagonally having to stop and pick at it. Section over joist would adhere very well but wrap over sides would not bond. Still marginally easier to work with than standard flashing tape and wider than box store joist tape that gives you silly 1/16” side error on 2X at 1 5/8”. Recommend 3035 over this but not sure it’s still available.
