Sealing/Jointing Tape – Black - Biokil Crown
Butyl Adhesive Tape for Overlaps and Detailing in Cavity Drain Membrane Systems
Biokil Crown Sealing/Jointing Tape – Black is a high-performance, double-sided butyl adhesive tape designed for joining and sealing overlaps between sheets of cavity drainage membranes. It creates a watertight bond that prevents moisture ingress at membrane joints and detailing points such as wall junctions and service penetrations. Essential for use in internal waterproofing, basement tanking, and damp-proofing systems, the tape ensures full membrane integrity in both vertical and horizontal applications.
Key Features & Benefits
- Watertight Membrane Sealing: Creates a secure seal between membrane overlaps and perimeter junctions.
- Flexible Application: Conforms to uneven surfaces and detailing areas without compromising adhesion.
- Strong Butyl Adhesive: Long-lasting, pressure-sensitive sealant for reliable performance in damp environments.
- System Compatible: Designed for use with Biokil Crown and Newton System 500 cavity membranes.
- Fast Installation: Peel-and-stick design for easy on-site application with no curing time required.
Product Details
- Type: Double-sided butyl sealing tape
- Colour: Black
- Width: Typically 30mm–50mm (confirm specific product variant)
- Length: Typically 20m per roll
- Application Areas: Membrane overlaps, internal/external corners, service penetrations
- SKU: BCSTBLACK
Application Instructions
- Prepare Surfaces: Ensure membranes are clean, dry, and free from dust, grease, or debris.
- Apply Tape: Position tape along the edge of the membrane sheet and press firmly into place.
- Join Overlap: Press the second membrane sheet onto the exposed adhesive surface, ensuring a tight, even seal.
- Secure Seal: Apply consistent pressure using a roller or hand tool to achieve full adhesion across the joint.
Limitations
- Do not use on wet or frozen surfaces.
- Not suitable for external applications exposed to direct sunlight or weather without protection.
Health & Safety
Wear gloves during handling. Avoid prolonged skin contact with adhesive surfaces. Refer to the product Safety Data Sheet (SDS) for full guidance.
