GRUNT self adhesive flashing tape is a 50mm x 10m bitumen-backed waterproofing tape for sealing and weatherproofing. The bituminous adhesive sticks firmly to clean, dry surfaces to form an instant waterproof seal, which is why it is a go-to grunt flashing tape for both planned work and quick fixes.
To apply GRUNT flashing tape, work on a clean, dry surface and press the tape down firmly so it bonds. It is well suited to new work or emergency repairs wherever a fast, waterproof flashing seal is needed.
