Product Information

Full details

The Radon DPM Jointing Tape is designed for professionals and DIY enthusiasts who require a robust and reliable sealing solution for damp-proof membrane (DPM) applications and other heavy-duty construction needs. Its primary benefit is providing a strong, water and water vapour resistant barrier, ensuring the integrity of your installations. A potential caveat is its need for proper surface preparation for optimal adhesion. This double-sided tape offers exceptional puncture resistance and long-term durability, making it suitable for demanding environments where moisture protection is critical.

FAQs

What is BBA approval?

BBA stands for the British Board of Agrément. BBA approval signifies that a product has undergone rigorous assessment, including testing, inspection, and certification, to demonstrate its fitness for purpose and compliance with building regulations and industry standards, particularly for construction products.

Can this tape be used outdoors?

While the tape is water and water vapour resistant, its long-term outdoor durability may depend on UV exposure and environmental conditions. It is primarily designed for use within building structures where it is protected from direct weathering.

How long will the adhesive last?

The tape is constructed with high-quality materials for long-term durability and seal integrity. When applied correctly and protected from extreme conditions, it is designed to provide a lasting moisture barrier.

What is the best way to apply pressure for bonding?

Firm, even pressure is crucial. You can use your hands to press down firmly, or for the best results, use a hand roller designed for DPM or flooring applications to ensure consistent pressure across the entire seam.

Can I use this tape on materials other than DPM?

Yes, the tape is suitable for various heavy-duty applications and can be used on compatible construction materials like concrete, wood, and rigid insulation boards, provided the surfaces are clean and dry for optimal adhesion.

What are the dimensions of the tape?

Each roll measures 50mm in width and 10 metres in length.

Is this tape permanent or temporary?

While it creates a durable and long-lasting seal, it is often used in construction for temporary moisture barriers during build phases. However, its sealing properties are designed for permanent moisture protection within a building structure.

Troubleshooting

Tape not adhering well

Ensure surfaces are completely clean, dry, and free from dust, oils, or moisture. Re-apply pressure to the taped seam, potentially using a roller.

Difficulty peeling backing paper

Ensure the tape is applied to the first surface before attempting to peel the backing. If the backing tears, carefully lift and continue peeling. Store tape in conditions that prevent extreme stickiness.

Seam appears to be leaking moisture

Check for any gaps or areas where the tape may not have adhered fully. Apply additional tape or reinforce the existing seam, ensuring proper pressure is applied.

Tape loses tackiness in cold conditions

Warm the surfaces and the tape slightly before application. Avoid application in sub-zero temperatures if possible, as adhesive performance can be affected.

Pros and Cons

Pros

BBA-approved for critical damp proofing applications.
Excellent resistance to punctures, ensuring seal integrity.
Effective barrier against water and water vapour.
Strong, reliable bond due to double-sided adhesive.
Durable and long-lasting performance.
Suitable for both professional and DIY use.

Cons

Requires clean, dry surfaces for optimal adhesion.
Not designed for extreme temperature fluctuations without additional measures.
May require significant pressure to ensure full bond activation.
Clear color might be visible on some finished surfaces if not covered.

Setup, Compatibility & Care

Setup:

Surface Preparation: Ensure the surfaces to be joined are clean, dry, and free from dust, grease, and any loose debris. For best results, surfaces should be smooth.
Application: Peel back a section of the backing paper. Carefully align the DPM or material and press the exposed adhesive firmly onto the surface. Then, slowly peel away the remaining backing paper while simultaneously pressing the second surface onto the exposed adhesive.
Bonding: Apply firm and even pressure across the entire taped area. A roller can be used to ensure maximum adhesion and remove any air pockets.

Compatibility:

Primarily designed for use with Damp Proof Membranes (DPMs) and other polyethylene sheeting.
Compatible with various construction materials such as concrete, brick, wood, and rigid insulation boards.
Always test on a small, inconspicuous area if unsure about compatibility with specific materials.

Care:

Store unused tape in its original packaging in a cool, dry place, away from direct sunlight and extreme temperatures.
Avoid prolonged exposure to temperatures above 70°C (158°F) or below -20°C (-4°F).
Keep the roll clean and protected from contamination before application.
