  • Applies well, backing peels off without issue
Size: 3" x 50' 2pack
I used the 2 inch version of this as well, and had a fair amount of issues getting the backing to peel off nicely. I did not have any of those issues with this bigger roll. I got the bigger ones thinking they'd be better for my double joists around the perimeter of the deck, however I probably should have looked more closely. These rolls are only 3" and the double joists are a bit over 3" in places where the boards are not straight so they don't work well for that. The 2 inch rolls are pretty good at covering single joists themselves, and at the time I got these, they were less than half the price of the 3" rolls. Unless you you need the 3" size for something specific, I think the 2" ones are a better value and option for single joists. Otherwise the adhesion and use of these ones are as expected. ... show more

  • Pretty Decent Deck Joist Tape
Size: 3" x 50' 2pack
The 3 inch width is ideal for covering double deck joists. Most deck designs end up having some doubled up deck joists, and the 3 inch width of this stuff is the way to go, it reduces the chances of water getting between two narrower strips (and between your doubled up joists - preventing rot), but it is twice as fast to install vs. two strips side by side. Earlier this season had the chance to compare 4 different lesser known brands of deck joist tape. They all look the same, with a smooth pliable black outer layer, and a fairly thick sticky gray adhesive on the inside protected by a peel-away backer. For the test, I placed strips of each to a piece of PT wood, and left out in the sun and elements for days, and then tested which ones adhered the best. The results were all pretty close. They all stuck pretty well, even after just a few days. I found that JOAPRIL stuck the 3rd best in my line up as it was the 3rd most difficult to peel off out of the 4 that I tested, but the rest were all pretty close contenders (with marginal difference in adhesion strength). All in all, I think this is a pretty decent product that will, ultimately, get the job done! ... show more

  • Tape makes flashing quick
Size: 3" x 50' 2pack
Nicely packed rolls. Love that they are individually wrapped so they didn’t stick together, and you can start one roll without compromising the second roll’s packaging. Easy to peel and apply, but like all flashing tape, don’t let it stick to itself! If you’re still trying to wrap aluminum around complicated decking flashing you’re wasting time when products like this are out there. ... show more

  • Does its job
Size: 3" x 50' 2pack
Wide and sticky tape. It's really 3" wide. You can cut it in half and double the length for 2-inch lumber (which is actually 1.5"). It's a little thin in my opinion. Other than that, pretty good Joist Tape. Does its job.

  • Excellent Protection for Deck Joists - 3”x50’ Self-Adhesive Deck Joist Tape
Size: 3" x 50' 2pack
I recently used the 3”x50’ self-adhesive deck joist tape for my deck project, and I must say that it exceeded my expectations in terms of quality and effectiveness. This tape has proven to be an essential addition to my deck construction, providing excellent protection to the joists against moisture, rot, and decay. The self-adhesive feature of this deck joist tape made the installation process a breeze. I simply peeled off the backing and applied it directly onto the joists. The adhesive was strong enough to securely bond the tape, ensuring long-lasting protection for my deck structure. It adhered well to the surface and remained firmly in place, even during heavy rain showers. One of the standout features of this tape is its ability to create a reliable moisture barrier. With the 3-inch width and 50-foot length, it covered a significant area, effectively sealing the gaps and preventing water penetration. This is particularly crucial for maintaining the integrity of the joists, as they are often susceptible to moisture-related issues over time. The tape also acts as a barrier between the joists and the deck boards, reducing the risk of water infiltration and potential rotting. Another aspect worth mentioning is the versatility of this product. It can be used on various types of decking materials, including pressure-treated wood, composite, and PVC. This makes it a reliable choice for a wide range of deck construction projects. In conclusion, the 3”x50’ self-adhesive deck joist tape is a superior product that I highly recommend for anyone undertaking a deck construction or renovation project. Its easy installation, moisture barrier properties, durability, and versatility make it an excellent investment. With this tape, you can ensure long-lasting protection for your deck joists, giving you peace of mind and extending the life of your deck. ... show more

  • Works great and holds well - don't slide your boards on it until you screw them in
Size: 3" x 50' 2pack
I got this to go onto my new deck install which is around my salt-water pool. I know water itself wears on a deck so I am hoping that this will help out since I have salt in my pool as well. There is a lot of tape on these two rolls and I was able to put tape on a 24'x18' deck main support beams and about 8 of the 2x6 joist with using both of them. I could have used more but I covered enough so that the salt water will not reach unless someone is really just throwing it on the deck. It just happened to rain immediately after I stuck the tape on the joist and it beaded right up where the rest of the pressure treated wood soaked the rain right in. These stick fairly well and you can reposition the tape if you don't press down super hard otherwise it will mess up the tape and it won't stick as well when you try again. The only thing to watch out for is when you go to slide your boards across the joist make sure to pick them up or slide them on other deck boards as it will roll the tape off some. Once you screw the board down this tape will go nowhere. For the price this isn't a bad investment if it just half-way works in the long run to extend your deck life. ... show more

  • Works well. Good value.

Works good. Good adhesion. Unrolls easily. I expect it will hold up well but only time will tell.
