How To Install Butyl Deck Joist Tape?

If you're planning to build a deck, you've probably heard of butyl deck joist tape. This tape is installed on the top of the deck joist to prevent water from seeping into the screw holes and rotting the wood. But how do you install it? Here's a step-by-step guide:

Step 1: Prepare The Surface

Before you start installing the tape, you should clean the surface of the deck joists. You can use a wire brush to remove any dirt, debris, or rust.

Step 2: Measure And Cut

Measure the length of the deck joists and cut the butyl tape strips accordingly. Make sure that you leave an inch or two at the end of each joist for easy handling.

Step 3: Install The Tape

Peel off the backing paper of the butyl tape and align it over the top of the joist. Press the tape down firmly, making sure there are no air bubbles.

Step 4: Seal The Joints

Overlap the butyl tape strips occasionally to create a watertight seal. Make sure that there are no gaps between the tape pieces as these can cause water to seep through.

Step 5: Secure The Decking

Once the tape is in place, you can start securing the decking boards. Use stainless steel screws to secure the boards to the joists. The butyl tape will act as a barrier, preventing water from seeping into the screw holes.

Installing butyl deck joist tape is a simple but important step in building a deck. It will help protect your investment from moisture damage and increase its lifespan. With the right tools, materials, and instructions, you can easily install butyl tape and enjoy a beautiful, sturdy deck for years to come.
