Decking tape, also known as joist tape or flashing tape, is an essential component in the construction of a long-lasting and weather-resistant composite deck. This adhesive tape is designed to protect the timber substructure of your deck from moisture, rot, and weathering, ultimately extending the life of your deck frame. In this comprehensive guide, we’ll dive into the details of what decking tape is, how it works, and why it’s crucial for maintaining the integrity of your composite decking.
What is Decking Tape?
Decking tape, or joist flashing tape, is a self-adhesive tape specifically designed to seal and protect the timber joists and substructure of your deck. It is typically made from a strong polymer acrylic adhesive that creates a permanent bond with the timber, effectively sealing out moisture and preventing rot. Deck tape is available in various widths, with 50mm and 65mm being the most common sizes.
At Ecoscape, we offer Deck Tape, a high-quality, non-butyl self-sealing tape manufactured from a massively strong polymer acrylic adhesive. This tape is designed to protect any timber decking substructure, ensuring a completely waterproof and weatherproof seal that adds to the life of your deck frame.
How Does Decking Tape Work?
Decking tape works by creating a barrier between the timber joists and the elements, preventing moisture from penetrating the wood and causing rot or decay. The tape is applied along the top of the joists before the deck boards are installed, ensuring that any water that seeps through the gaps between the boards will not come into direct contact with the timber substructure.
The adhesive on the tape forms a permanent bond with the timber, creating a seal that lasts for the lifetime of your deck. This bond is so strong that our Walther Strong Deck Tape comes with a 25-year guarantee, giving you peace of mind that your deck frame is well-protected.
Benefits of Using Decking Tape
- Prevents Rot and Decay: By sealing out moisture, decking tape helps prevent rot and decay in the timber joists, extending the life of your deck frame.
- Protects Against Weathering: Deck tape acts as a barrier against the elements, protecting your deck substructure from weathering caused by rain, snow, and sun exposure.
- Maintains Deck Integrity: By keeping the timber joists dry and free from rot, decking tape helps maintain the structural integrity of your deck, ensuring that it remains safe and stable for years to come.
- Easy to Install: Applying deck tape is a simple process that can be done by any DIY enthusiast. Simply clean the surface of the joists, cut the tape to the desired length, and press it firmly onto the timber.
- Compatible with Various Timber Treatments: Our Walther Strong Deck Tape has been tested with all timber treatments, including galvanised fixings and treated timber, ensuring a strong and lasting bond.
How to Apply Decking Tape
- Ensure that the surface of the timber joists is clean, dry, and free from debris.
- Cut the deck tape to the desired length, allowing for a slight overhang on each end of the joist.
- Peel back the protective backing on the tape and align it with the top of the joist.
- Press the tape firmly onto the timber, using a roller or your hand to ensure a strong adhesive bond.
- Repeat the process for all joists, ensuring that the tape is applied in a continuous strip along the entire length of each joist.
- Once the tape is applied, you can proceed with installing your composite deck boards as planned.
