Section 1: Understanding Deck Frame Weathering

Your deck’s substructure faces relentless exposure to the unpredictable outdoor elements, making it vulnerable to the gradual wear and tear known as deck frame weathering. The primary battleground for this damage lies precisely where your deck boards meet the substructure. It’s in this critical junction that Walther Strong Deck Tape emerges as the hero, providing more than just a defense – it’s a fortified shield against water rot, moisture damage, and the relentless forces of weathering. Let’s delve into the intricacies of how this exceptional tape seals and protects, ensuring your deck stands strong against the test of time.

Section 2: Benefits of Using Deck Tape®

1. Watertight and Weatherproof:

   Walther Strong Deck Tape® offers a completely waterproof and weatherproof seal, protecting your deck frame from moisture-related issues. This feature is essential for areas prone to heavy rain or fluctuating weather conditions.

2. Easy Release and Stickiness:

   The tape boasts easy release properties, making installation hassle-free. Its superior stickiness ensures a strong and enduring bond, contributing to the overall stability of your deck structure.

3. UV-Stable and Self-Sealing:

   UV stability is crucial for outdoor applications. Walther Strong Deck Tape® maintains its integrity in all weather conditions, from scorching sun to freezing temperatures. Additionally, it is self-sealing, preventing water infiltration and protecting against frame weathering.

4. Compatibility with Various Deck Materials:

   Whether you have a traditional timber deck or a modern composite deck, Deck Tape® is compatible with both. It ensures that your deck frame remains protected, especially when using composite boards that can absorb more moisture.

5. Low Maintenance and Eco-Friendly:

   With a 50-year permanent adhesive bond and a 25-year guarantee, Walther Strong Deck Tape® reduces the need for frequent maintenance. The use of sustainable materials aligns with eco-conscious practices, making it an environmentally friendly choice.

Section 3: Where to Apply Deck Tape®

1. Joist Protection:

   Applying Deck Tape® along the top of joists creates a robust seal, preventing moisture from sitting on flat surfaces and causing timber rot. The tape can be applied in advance to deck boards, ensuring no compromise on its protective qualities.

2. Joist Hanger Protection:

   Deck Tape® serves as a protective layer on metal joist hangers, preventing the breakdown of treatments and maintaining the subframe’s integrity over time.

3. Posts and Cut Ends:

   Seal timber posts and cut ends with Deck Tape® to create a waterproof and moisture-tight barrier. This is particularly useful for fence posts and areas where timber has direct contact with the ground.

4. Around Fasteners:

   Applying Deck Tape® between galvanized fixings and treated timber prevents corrosion, ensuring the longevity of the fasteners and maintaining the structural integrity of the deck.

Section 4: Using Deck Tape® with SmartBoard® Composite Decking

Walther Strong Deck Tape® not only harmonizes seamlessly with traditional timber decking but also pairs exceptionally well with advanced composite decking solutions like SmartBoard®. To optimize its effectiveness in conjunction with SmartBoard® decking, consider the following recommended application method:

1. Selecting Quality Timber Joists:

   Begin by choosing a high-grade C24 treated UC3 or UC4 Timber joist when incorporating SmartBoard® decking into your outdoor space.

2. Optimal Deck Tape® Width:

   For SmartBoard® decking applications, it is advisable to utilize the 65MM Deck Tape®. This width has been found to be particularly effective in managing moisture, especially given the unique characteristics of composite deck boards.

3. Proper Application Technique:

   During application, carefully affix the 65MM Deck Tape® along the top of the joists. Pay close attention to avoiding any undue pressure on the sides, ensuring the tape remains elevated and does not droop or sag along the edges. This meticulous approach guarantees that water droplets will run off the tape onto the ground, preventing direct contact with the timber and mitigating potential moisture-related issues.

Enhance the performance and longevity of your SmartBoard® composite decking with Walther Strong Deck Tape® — a dynamic duo that not only elevates the aesthetics of your outdoor space but also ensures enduring protection against the elements.
