Application steps

EQUIPMENT

Hot welding overlap seams
Electric hot-air welding equipment, such as hand held manual hot air welding equipment and pressure rollers or automatic hot air welding   machines with controlled hot-air temperature capability of a minimum +600 °C.

SUBSTRATE QUALITY

The substrate surface must be uniform, smooth and free of any sharp protrusions or burrs, etc. Sarnafil® G 410-12 L must be separated from any incompatible substrates / materials by an effective separation layer to prevent accelerated ageing. The supporting layer must be compatible to the membrane, solvent resistant, clean, dry and free of grease and dust. Metal sheets must be degreased with Sarna Cleaner before adhesive is applied.

APPLICATION

Installation procedure
Strictly follow installation procedures as defined in method statements, application manuals and working instructions which must always be adjusted to the actual site conditions.


Flashings
Refer to standard details in Application Manual                                               

Hot welding overlap seams
Overlap seams must be welded by electric hot welding equipment. 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 conditions prior to welding. The effective width of welded overlaps by hot-air must be a minimum 20 mm.

Testing overlap seams
The seams must be mechanically tested with screw-driver (rounded edges) to ensure the integrity/completion of the weld. Any imperfections must be rectified by hot air welding.
