Product Overview

Protect your deck substructure and extend the life of your deck with Protective Joist Tape. When applied to deck joists, Protective Joist Tape creates a waterproof membrane that prevents wood rot and decay caused by the accumulation of moisture under the deck boards. Protective Joist Tape self-seals around screws and nails, blocking the primary pathway of water into lumber. When placed between treated lumber and metal, Protective Joist Tape eliminates the potential for the corrosion of the metal surface.

Will this adhere to old joists where we’re replacing the decking boards. Joists are moist from rain

I used this tape on existing joists that were damp, but not wet with water. I first lightly sanded the joists to remove old dirt and grime and the tape stuck to the damp joists extremely well. Once the tape was exposed to direct sunlight and higher air temperatures, it stuck so well, it was almost impossible to remove.

can this tape be used satisfactorily over- lapping to cover 3" girders/joists

Yes, as long as there is the slightest overlap of the tape, the tape will stick together and form an very good bond that will prevent water from penetrating. If you let the tape be exposed to either direct sunlight or high air temperatures, the butyl on the tape seems to "melt" into the other tape when it warms. I found if you accidentally allow the sticky side of the tape to touch the top of another piece of the tape, it is almost impossible to separate without tearing the tape.

Is this safe to use under PVC decking such as Azek Harvest decking?

Asked by Badger62 June 14, 2020

Answers

This Butyl tape is specifically made for covering wooden joists, so I assume you plan to use it for that purpose. As Azek Harvest decking is a Timbertech product, it is made from recycled plastics covered in a PVC (Polyvinyl Chloride), an inert plastic material. I do not believe there would be any danger from a chemical reaction between the plastic decking and the tape. The adhesive is on the back of the tape itself, which appears to be of a plastic nature, and does not contact the decking. I have used this joint tape under Trex decking, which is similar to the Timbertech products, and it was recommended by Trex to install the tape to prevent rotting and decay. The tape sticks very well to the joists and once the sun heats the tape, the tape is securely "stuck" to the joist and very difficult to remove. I would recommend using the tape as it does the intended job without any safety issues that I am aware.

I'm a vet - what I learned is that we can only get a discount if the item that we're buying online is ALSO in stock at a store. I'll buy online, and then at a later date bring in my receipt to get the discount. Sometimes I'll do in-store pickup, so that I can do a quick pickup and then get the discount all at the same time.

Difficult packaging and application
Once the package and backing have been removed it seems to stick and do the job, the problem is getting it out of the packaging as everything stuck to the side of the rolls so bad. While trying to apply the tape, the backing wouldn’t come off clean and would rip about every 6-8”. It took us over 2.5 hours to apply 7 rolls of tape to our deck frame. I’m sure there are better products available and if they are more expensive probably worth saving the time. How much is your time worth?

This product should be taken off the shelves by HD! Read other reviews and you will learn that the backing will separate and not come off the rubber adhesive. Spend a little more and get a decent product from Trex. The savings is not nearly worth the frustration!!

You can not pull it apart more than 2 feet without the backing ripping. Awful

I wanted to salvage and re-use my deck's 'under-structure'--joists and beams. With over 1000 exposed holes from the old deck screws--What to do about that? This tape was the right answer. It is easy to apply and provides protection to add many years to my new deck and old structure.
