Heavy-Duty Waterproof Repair Tape

A roll of heavy-duty tape built for leaks, cracks, and gaps.

• Bonds to most surfaces instantly
• Handles up to 3 bars pressure
• No tools needed for application

You notice a drip coming through the roof, or a crack along the window sill that keeps letting moisture in — and you need a fix fast without calling a contractor. This waterproof adhesive tape is built for exactly those moments. The synthetic butyl rubber construction bonds firmly to surfaces on contact, making it suitable for use on roofs, corrugated panels, gutters, pipes, and even car bodywork. The pressure-resistant design handles up to 3 bars, so it holds up even where water is actively pushing through. No special tools are needed — just clean the surface, apply the tape, and let it set for 24 hours. Available in multiple sizes, it works for everything from a small patch job to a longer sealing run.

Firm, reliable bond
The synthetic butyl rubber construction with high polymer content grips tightly to most surfaces. It forms a dense, gap-free seal when pressed into place.

Handles wet conditions
The tape's outer layer is designed to repel water and stand up to outdoor weather exposure. It works on surfaces that are prone to moisture contact, such as roofs, pipes, and gutters.

Pressure-resistant construction
Rated to handle pressures up to 3 bars, this tape is suitable for areas with active water pressure. The thick adhesive layer distributes force evenly across the repair area.
