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.
Recommended type of equipment:

• Manual: Leister Triac

• The supporting structure must be of sufficient structural strength to apply all new and existing layers of the roof build-up. Complete roof system must be designed and secured against wind uplift loadings.
• The substrate surface must be uniform, smooth and free of any sharp protrusions or burrs, etc.
• Sikaplan® D-18 (CH_CE) 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.

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.

Reference must be made to the following Installation instructions:

• Sikaplan® G-types for mechanical fastened system
• Sikaplan® SGK-types for partially adhered system
• Sikaplan® SGmA-types for ballasted system

Fixing method
The detailing membrane is welded to the installed PVC roof waterproofing membrane.

Hot welding method
Overlap seams between the detailing membrane and waterproofing membrane 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 before welding. The effective width of welded overlaps by hot air must be minimum 20 mm.

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