Sealing Tape Tesa 56481 Under Water Tape 50 mm x 1.5 m for Wet and Underwater Repairs

Tesa Under Water Tape 56481 is a 50 mm wide, 1.5 m long sealing tape engineered for wet and underwater repairs. The tape forms an immediate waterproof seal that adheres without the need to dry the surface first, enabling fast temporary repairs on pipes, hoses, fittings and other components exposed to moisture. Designed for applications where conventional adhesive tapes fail in the presence of water, this product is suitable for emergency fixes and routine maintenance in marine, pool and outdoor plumbing environments.

Advantages

The tape provides instant sealing performance on wet surfaces and underwater, maintaining adhesion and resistance to water pressure for temporary containment and leak reduction. Its construction yields a flexible and conformable band that wraps tightly around irregular shapes and fittings, creating a uniform barrier. The compact roll is easy to carry and apply, allowing quick intervention without special tools or surface preparation.

Suitable for

• Temporary sealing of leaking pipes and hoses
• Emergency repairs on boats, marinas and watercraft systems
• Pool and spa maintenance for short-term fixes
• Outdoor plumbing where immediate adhesion in wet conditions is required
• Repair of garden hoses, irrigation lines and fittings

Key specifications

• Width: 50 mm
• Length: 1.5 m
• Intended use: wet and underwater sealing
• Function: self-adhesive, conformable sealing tape for temporary repairs
• Performance: immediate waterproof seal on wet substrates
• Material properties: flexible and stretchable to form a tight wrap

How to use

Cut or tear an appropriate length of tape and stretch it while wrapping tightly around the damaged area, overlapping each turn to ensure continuous coverage. For leaks under pressure, apply several layers with firm tension to build a secure seal; ensure the tape extends beyond the damaged section onto intact surface on both sides. No surface drying is required, but remove loose debris or heavy contaminants where possible to aid conformity. After application, allow any trapped water to be contained by the tape; monitor the repair and replace with a permanent solution when feasible.

Usage recommendations

Use this tape for short-term or emergency repairs only. For permanent fixes, plan a proper repair or replacement as soon as conditions allow. Avoid using the tape on surfaces with heavy oil, grease, or abrasive damage that cannot be removed; follow safety practices when working near pressurized systems and electrical components.
