Description
The application surface must be dry, free of dust and grease. Surface elements must be removed so that the membrane is not damaged during application.
Recommended use: Direct UV protection is guaranteed. Installation is therefore permitted on both the internal and external sides of the building envelope.
Installation: Unroll the membrane. If the version without double-sided adhesive strips is used, sealing must be carried out using tape such as: FLEXY BAND, FLEXY BAND UV, SPEEDY BAND, or EASY BAND.
Ensure that the overlap between the membranes is at least 15 cm to achieve an optimal seal.
To ensure correct and professional installation, the use of a nail sealing point is required.
Further details regarding installation can be found in the specific instructions provided by the supplier.
