TREX Protect Joist & Beam Tape

$35.09$178.46 + HST

  • Protects the top of the joist, beam, and rim joist from developing rot and wood decay

  • Acts as a barrier between the 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 25-year warranty

Simple Three-Step Installation Process

  1. Clean the joist surface making sure it is dry and free of debris.
  2. 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 beams.
  3. After covering all horizontal and vertical surfaces, cut the tape to length with a utility knife or scissors.


  • Apply to horizontal and vertical surfaces including all joists, rim joists, beams, steps, stair stringers, blocking, ledger board, and under joists hangers.

    • Use 1-5/8″ x 50′ (41.3 mm x 15.24 m) Joist Tape for joists;
    • Use 3-1/8″ x 50′ (79.4 mm x 15.24 m) Beam Tape for all double beams;
