Why Choose Walther Strong for Your Next Project?

When building outdoor structures like composite or traditional timber decking, protecting your subframe is just as vital as choosing the right surface boards. Timber joists are naturally susceptible to moisture build-up, dampness, and eventual rot. Walther Strong has developed industry-leading solutions designed to stop water in its tracks, securing your hard work for decades to come.

The Ultimate Timber Protection: Walther Strong Deck Tape

At LB Supplies, we stock the highly acclaimed Walther Strong deck tape, a must-have for installers and DIY enthusiasts alike. This specialised flashing tape is applied directly to the top of timber joists and bearers before the decking boards are fixed down.

  • Complete Moisture Barrier: It creates a fully waterproof seal over joists, preventing standing water from seeping into timber grain and screw holes.
  • Self-Sealing Technology: When you drive decking screws or clips through the tape, it automatically seals around the fixings, ensuring no hidden pathways for water ingress.
  • High-Tack Adhesion: Designed to stick instantly to damp or dry timber, the permanent acrylic adhesive won’t peel or lift over time.
  • UV & Temperature Resistant: Built to survive extreme weather conditions without degrading, breaking down, or losing its protective properties.

Extend the Lifespan of Your Decking Subframe

Using high-quality joist protection tape, such as Walther Strong deck tape, can easily double the lifespan of an outdoor timber frame. By spending a little extra time during the subframe installation stage, you save thousands in potential future repair and replacement costs. It is the ideal companion for both premium wood and low-maintenance composite decking systems.
