Strong Adhesive Tape Protection for your Timber Joists!

Dindas Joist Tape is a protective tape designed for the top of deck joists, bearers and structural framing in outdoor decking systems. It helps reduce moisture penetration into timber framing, supporting the durability and long-term performance of deck substructures exposed to weather during service.

Butyl Adhesive for Reliable Bonding

  • High-tack butyl adhesive provides strong adhesion to clean, dry timber surfaces and remains flexible during installation.
    Flexible tape design allows quick installation along framing members.

Compatible with Treated Timber

  • Suitable for use on H3 treated timber, LVL, joists, bearers and other engineered timber framing commonly used in deck construction.

Protects Deck Framing from Moisture

  • Creates a protective barrier over the top of joists and bearers, helping reduce water ingress through screw penetrations and board gaps.

Designed for Deck Framing Protection

  • Protects the most exposed surfaces of deck framing where water commonly collects around fasteners and decking joints.

Helps Extend Deck Substructure Life

  • By protecting the most exposed surfaces of deck framing, Dindas Joist Tape helps extend the service life of joists, bearers and other structural members.
