Product Details

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.
  • Protect and maximize the life of your deck
  • When applied to the top of joists, this tape creates a barrier which helps prevent water damage and wood rot
  • Self-adhesive butyl tape
  • Easy to install
  • 1-5/8 in. x 50 ft.
  • Self-seals around screws and nails to prevent moisture penetration
  • Contractor Pack for 18 rolls

Q:Can I paint over this with water based primer?
by|Oct 28, 2022
3 Answers
Answer This Question

A:  Landscaper, while it's possible to paint these, no testing as been done to determine which paint will adhere to the tape.

by|Oct 31, 2022

    A:  I don't know why you'd want to. The black basically makes it disappear under the decking, but you could try a foot or so and see how it goes.

    by|Oct 30, 2022

      A:  I would not recommend painting the tape based on my usage. I believe the correct answer should come from the manufacturer.

        Answer This Question

        A:  RoyM, This tape is designed to be covered by decking materials and should not be left exposed to sunlight for an extended period of time.

          Q:Can i apply the tape in shorter lengths across the joists as I go still covering the entire joist but not in one full continuous strip. Will it stick to itself as I work across the deck joists and still protect properly or does it need to be a full strip.

          Answer This Question

          A:  RoyM, Yes you are able to work with this in shorter lengths and should stick to itself. When overlapping material from end to end, a minimum of a two-inch overlap is required.

          by|Aug 2, 2022

            A:  Yes. I cut it in smaller lengths to go around obstacles and it stuck to itself very well. In fact it sticks to just about anything.

              Q:can this butyl tape be applied on painted wood joist?

              Answer This Question

              A:  Kathy, There is nothing that states it cannot be applied to painted wood joists. If it adheres to pressure treated joist it should adhere to painted joists.

              by|Jun 9, 2022

                A:  Yes, very sticky, works great!

                by|Jul 6, 2022

                A:  Yes -- any clean surface works just fine.

                by|Jun 23, 2022

                A:  I did not apply my tape to painted joists. However this stuff is pretty sticky and I would think it would still adhere to a painted surface.

                  I was very happy with this tape. We did our best to clean off the old joists but they were still pretty crusty in some spots. I had no issues with the tape adhering to the joists. Also, I didn’t have any issues with the tape sticking to itself, which is often a problem.

                  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?

                    I have re decked a few decks in the past few years. I wish I knew about this product years ago! I would have been using it on previous jobs. I don't know how long it will last, but I feel confident it was the right thing to use on my project.
