- Acts as a barrier between wood and galvanized metal such as joist hangers
- Seals deck fasteners and prevents moisture penetration
- Eliminates splitting from freeze and thaw
- Provides a non-skid surface making it safer during installation
- Available in three widths for joists, double beams and rim joists
- Backed by a 20-year warranty

Simple Three-Step Installation Process
- Clean the joist surface making sure it is dry and free of debris.
- Remove the butyl tape backing while applying directly to the surface. Run your hand over the tape and firmly press it onto the joists and bearers.
- After covering all horizontal and vertical surfaces, cut the tape to length with a utility knife or scissors.
How it Works:
- Apply to horizontal and vertical surfaces including all joists, rim joists, beams, steps, stair stringers, blocking, ledger board, and under joists hangers.
- Trex Protect is available in three widths:
- Use 1-5/8″ x 50′ (4.13 cm x 15.24 m) Joist Tape for joists;
- Use 3-1/8″ x 50′ (7.94 cm x 15.24 m) Beam Tape for all double beams;
- Use 11″x50′ (27.94 cm x 15.24 m) Rim Tape for rim joists, stairs and all flat-blocked surfaces.
