Butyl Sealant Tape Double Sided Waterproof 2mm

This double sided butyl sealant tape is designed to create reliable airtight and watertight joints when joining membranes and foils in building and roofing work. It helps prevent draughts and moisture ingress, making it ideal for tidy, long-lasting seals on overlaps, joints and terminations.

Made from solvent-free butyl adhesive, the tape provides strong instant tack and conforms well to uneven surfaces for a secure bond. A silicone paper release liner makes it easier to handle, position and apply without the adhesive sticking to itself.

Use it for sealing connections between vapour barriers, roofing foils, construction foils, groundwork tapes and roof membranes. It also suits bonding these materials to common substrates such as concrete, brick and timber, where a dependable seal is required.

Choose the required width and length variant for your job, whether you are closing lap joints, detailing around edges, or sealing penetrations and repairs. For best results, apply to clean, dry, dust-free surfaces and press firmly along the full contact area.

Suitable for general DIY and trade use in building maintenance, refurbishments and new installations where a neat, durable membrane joint is needed.
