Installation Guides

Gerband 587 Waterproof Tape is an external membrane tape that’s permanently resistant to moisture.

Gerband 587 Waterproof Tape is wind-tight and temperature resistant. It also adheres excellently onto wood, smooth bricks and solid concrete surfaces. Gerband 587 can be bonded to porous or sandy substrates sufficiently if primed and can be used as a repair tape for damage or tears in membranes. Furthermore – it seals all known pitched roof underlay and façade membranes.

Carrier

Special film,
Filament protection against over-expansion,
Very pliant, even in frosty conditions,
Temperature-stable until 120°C,
UV resistant.

Adhesive

Polyacrylate adhesive,
Extremely high initial and permanent adhesion,
Good adhesive characteristics especially at low temperatures,
Very high tack,
Very good ageing resistance.

Features & Benefits:

Permanent resistant against moisture,
UV resistant for 12 months during direct solar radiation,
Not suitable for bonding under mechanical stress. Prior to the application with plastics test are necessary due to the possibility of plasticizer migration and stress corrosion. For safety reasons it’s necessary to check the adhesion between the tape and the membrane before using.

Application

Application Guide:

Apply at temperatures from -10C to 40C,
Store in dry rooms from 5C to 25C, protected from UV-radiation,
Surfaces need to be self-supporting, dry, clean, dust-free, and free of grease and other adhesive-repellent materials,
In case of porous surfaces pre-treatment with Butyl Primer 6000 is necessary,
Apply stress-free and press to surface thoroughly, adhesion increases with higher pressure,
Not suitable for bonding under mechanical stress. Prior to the application with plastics test are necessary due to the possibility of plasticizer migration and stress corrosion. For safety reasons it‘s necessary to check the adhesion between the tape and the membrane before using.
The tape and/or membrane should not be exposed to any mechanical strain.
