Snoop's Take

The Hanotic Joist Tape is a high-quality butyl tape designed to protect wood joists, decks, and beams from water damage and corrosion. It is self-adhesive, waterproof, and suitable for a wide range of surfaces, making it an ideal solution for extending the life of outdoor structures. Consumer sentiment around this product highlights its effectiveness and ease of use, with many users appreciating how it can prevent future water damage and reduce creaking between composite and wood framing. One user noted, "The intent of joist tape is to protect the framing from standing water and debris," which underscores its protective qualities. However, some users have expressed concerns regarding its long-term effectiveness, particularly for underwater applications, stating, "Not sure how long it will last but I'm sure it's not made for underwater use." Overall, the Hanotic Joist Tape is recommended for those looking to enhance the durability of their decks and joists. While there are some caveats regarding its application and effectiveness over time, positive feedback regarding its protective capabilities suggests it can be a valuable addition to deck maintenance.

What it does well!

Key strengths users can’t stop talking about.
Joist tape may prevent future water damage
I'm going to use it in hopes that it extends the life of the deck.
Joist tape is easy to use
Not a carpenter, this was my first deck build.
Joist tape can effectively fix leaks
It stopped the leak and was WAY easier to use underwater than the putty goop.
The tape fix is good.
Joist tape is quicker and safer than liquid applications
Tell me why I shouldn’t just roll on a coat of rubberized sealant versus tape?
Tape is quicker, easier and safer.
Tape is cheap
Tape is cheap.
Tape protects against standing water and rotting organic debris
The intent of joist tape is to protect the framing from standing water and debris.
Joist tape helps protect against water damage
From the looks of the build, I’d say you’ll be enjoying for years to come.
Looks great, nice work!!
Joist tape reduces creaking between composite and wood framing
it does noticeably reduce creaking between the composite and the wood framing.
Joist tape prevents water from sitting between deck boards and joists
I've heard the argument both ways: joist tape keeps water from sitting between the deck boards and joists (good). I've also heard the concern that the water ends up following the screws into the joist, but then can't escape because of the tape (bad).
Can help protect doubled up members from quick rotting
I saw that they're quick to rot - water sits between them etc.

Where it needs some work!

Areas to watch—feedback on possible improvements.
Difficult to use for temporary patches
That butyl tape will make you hate life when you go to patch it in the spring.
Difficult to determine effectiveness over time
but we still dont know if the tape works or not
Joist tape may not last long for underwater use
Not sure how long it will last but I'm sure it's not made for underwater use.
Joist tape can be difficult to apply, especially alone
I don’t know if I would say tape is easier, it was difficult to apply by myself on a 14 foot high deck.
Joist tape is not suitable for use as flashing
In hindsight I would have had him tear the whole thing down and build from scratch, because of all of the work arounds we had to do.
I personally would absolutely not use joist tape for flashing.
Insufficient evidence of tape's long-term effectiveness
I'm a bit on the fence on joist tape. It's a relatively new practice that doesn't have enough time and evidence of its effectiveness.
Tape may not be necessary for pressure treated wood
35 year old cedar deck on PT frame. No tape.

Core Power Plays

The specs and strengths that make it shine.
Joist tape may prevent future repairs
the ones that were have at least another decade in them.

Hidden Hero Hacks

Unexpected tricks and side‑door uses you’ll love.
Alternative patching materials are preferred
They can get ZIP tape at Lowe’s or Home Depot and as long as it’s clean and dry, it would hold them over for a couple of months even or until they can get a proper EPDM patch on it.
if you do want a temporary fix, I'd use Zip Tape over something like butyl tape.
Alternative methods are being explored for deck longevity
the small investment in joist tape to extend the life of the structure can significantly increase the usable life of the deck overall.
Maybe joist tape and a quick and efficient way to “Wet Install” the fasteners?

Buyer’s Cheat Sheet

What to check before you click ‘Add to Cart.’
Patching can be done in winter with proper conditions
With a clean dry area you could patch it correctly.
Usefulness depends on climate and location
In my non-professional opinion, it depends on location (both climate and setting).
Joist tape usage varies by climate and location
Lol, cool. So not much need for it in Arizona huh?
I explained that the tape would dry rot within a year but I COULD coat each screw shaft with silicone before fastening.

Cautionary Callouts

Know the pitfalls before they catch you off guard.
Some traditional methods still work for decking
If you’re worrying about butyl then you’re probably going to be fine in the long run because you’re a smart feller.
The copper treating is more reactive with the galvanized nail, which corrodes the nail, loosening the fit, letting in moisture and causing that dreaded squeak.
I’d say you explained this about perfectly, I’ve been working with my grandpa a general contractor for about a decade.
Debate exists between tape supporters and haters
The only thing that people agree on is tape if you want to, don’t tape if you don’t want to.
Questioning the tape's effectiveness for deck lifespan
it seems a bit of a gimmick. It's not something I'd refuse to use but also not something I would recommend.
Debate exists around the effectiveness and necessity of joist tape
Joist tape or not? Looking to get some of the experts opinion on doing joist tape.
