    Systems

    Sarnafil G 410 L is used as a detailing membrane in combination with Sarnafil S 327 L, Sarnafil G 410 L Felt and Sarnafil G 476.

    Installation

    Refer to the Sika Installation Manuals for single ply PVC membranes.

    Sarnafil G 410 L is bonded to the substrate by a suitable Sarnacol adhesive (see Sarnacol product documentation).

    Overlap seams are welded by electric hot air welding equipment, such as manual hot air welding machines and pressure rollers or automatic hot air welding machines with controlled hot air temperature.

    Recommended type of equipment: Leister Triac PID (manual welding) and Sarnamatic 661plus (automatic welding)

    Welding parameters including temperature, machine speed, air flow, pressure and machine settings must be evaluated, adapted and checked on site according to the type of equipment and the climatic situation prior to welding. The effective width of welded overlaps by hot air should be minimum 20mm.

    The seams must be mechanically tested with screw driver to ensure the integrity / completion of the weld. Any imperfections must be rectified by hot air welding.

    Restrictions

    Installation works must be carried out only by Sika instructed and approved roofing contractors.

    Temperature limits for the installation of the membrane:

    Substrate temperature: -30 °C min. / +60 °C max. Ambient temperature: -20 °C min. / +60 °C max.

    Installation of some ancillary products, e.g. contact adhesives / cleaners is limited to temperatures above +5 °C. Please observe information given by Product Data Sheets.

    Special measures may be compulsory for installation below +5 °C ambient temperature due to safety requirements in accordance with national regulations.
