Application

Application Guide:

Store in dry rooms from +5C to +25C, protected from UV-radiation.
The membrane should be applied perpendicular to the direction of the application surface i.e. studs, rafters and joists.
The membrane should be fixed with staples every 150mm or double-sided tape.
Gerband 586 or a suitable grommet should be used for penetrations.
For bonding barrier overlaps, penetrations and repair spots, Gerband 586 or a similar tape is recommended
For connections to concrete or masonry Fortax 6400 is recommended.
Ensure there is a 100mm overlap of the membranes and tape with Gerband 586 or another suitable tape.
Ensure the corner overlaps are completely sealed.
