Supraseal® Black Weatherproofing Tape 200mm x 10m – Butyl Flashing Tape

Supraseal® Black is our cold-applied, self-adhesive butyl tape with a black facing, for repairs and flashings where you want the tape to disappear against black EPDM, felt, bitumen, guttering or dark cladding. It rapidly seals leaks in roofing membranes, gutters and flashings, seals between dissimilar single-ply membranes and works as a lead flashing alternative. It's completely bitumen free and creates a waterproof seal in minutes.

• Black finish: blends in on black and dark roofs, gutters and trims.
• Seals in minutes: cold applied, with no torch or liquid. The bond strengthens over time.
• Bitumen free: butyl based and non-staining on plastisol-coated steel.
• Built to last: UV stable, waterproof and airtight, from -30°C to +80°C.
• Moves with the roof: stays flexible as the roof heats and cools, and doesn't harden in sunlight.
• 10-year warranty.

Where to use it

Lean-to roofs, conservatories, carports and canopies where polycarbonate sheets meet a wall; chimneys and roof lights; cladding and facade joints; gutters and flashings; caravans and motorhomes; and air-conditioning pipework where it passes through a wall.

Fitting tips

• Make sure the surface is clean, dry and free of dust and grease.
• On polycarbonate, don't clean with solvents: use soapy water and let it dry.
• Overlap joins by at least 50mm.
• Press it down firmly with a seam roller, working out any air.
