Why it works

Built for membrane jointing

Bonds to a wide range of substrates

The high-tack butyl adhesive holds firm across a wide range of construction substrates.

Conforms to uneven surfaces

The softer butyl composition moulds to textured or irregular surfaces for a tight joint.

Stays flexible

The tape remains flexible throughout the life of the joint, rather than hardening over time.

Clean application

Frequently asked questions

What is butyl mastic tape used for?

It is a high-tack jointing tape for vapour barrier and damp-proof membranes (DPM), bonding membrane-to-membrane or membrane-to-substrate joints on construction and groundworks sites.

Will it bond to an uneven or textured surface?

Yes. The softer butyl composition is designed to conform to uneven and textured substrates, not just smooth ones.

Does the tape stay flexible once applied?

Yes, it remains flexible throughout the life of the joint rather than hardening or cracking over time.

What size is the roll?

Each roll is 50mm wide and 10m long, at 1.5mm thick.

Is there a backing to peel off before use?

Yes, the tape is protected by a siliconised paper release liner that peels away as you apply it.

What colour is the tape?

Black.

Is this tape adhesive on both sides?

Yes, it is a double-sided butyl mastic tape, so both faces bond.
