Felizshop ZCX-Tape-3-2R. Butyl Joist Tape, 3" x 50', Waterproof

When building or maintaining a deck, cover joists and beams with a protective layer before installing the boards. Felizshop butyl joist tape is 3 inches wide, giving you a broader strip for deck framing. Need tape for more than wood? It is listed for use on wood, metal, glass, plastic, and rubber surfaces.

Tips for day-to-day use

Start with a clean, dry surface free of debris so the adhesive can make contact. Measure and cut the tape to the length you need, peel away the backing, and apply it smoothly. Press it down along the surface for better adhesion, especially around joists, beams, and nail locations. For deck projects, this makes it practical to cover framing as part of the build or maintenance process, before the finished deck surface goes on.

The 3-inch-wide roll offers more coverage across a joist face than a narrower strip, while the 50-foot length gives you a continuous run to measure and cut for the task. Use it for deck joists and beams, or for other listed applications such as roof repairs, pipe work, and gutter leak repairs. The butyl adhesive is double-sided, and the tape is described as waterproof and weather resistant.

What you’ll notice day to day

This is a flexible rubber and butyl tape designed to form a protective layer over framing and other surfaces. Its waterproof, corrosion-resistant properties make it useful where exposed wood, beams, or fasteners need protection from water or chemicals. The product is rated for temperatures from -20°F to 176°F, supporting use across a range of outdoor conditions.

Buyer feedback describes the tape as useful for applications including deck joists and sealing doors or windows. Comments on adhesion are mixed: some buyers say it sticks well, while others find it less adhesive than other tapes or report it sticking to itself. Some also mention that the backing can tear during removal. Applying it to a clean, dry surface and pressing it down as directed can help with placement.
