EQUIPAMENTO

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
Automatic: Leister Varimat or similar
Semi-automatic: Leister Triac Drive

QUALIDADE DA BASE

The substrate surface must be uniform, smooth and free of any sharp protrusions or burrs, etc. Sikaplan® G-18 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 Sika® Trocal Cleaner-2000 before adhesive is applied.

 

APLICAÇÃO

Installation procedure

Reference must be made to further documentation where applicable, such as relevant method statement, application manual and installation or working instructions.

Fixing method – General

The waterproofing membrane is installed by loose laying (without stretching membrane or installing under tension) with mechanical fastening in seam overlaps or independent from overlaps. Overlap seams are hot welded using specialised hot air equipment.

Fixing method-Spot fastening

Sikaplan® G-18 must always be installed at right angles to the deck direction. Sikaplan® G-18 is fixed by fasteners and washers/tubes along the marked line, 10 mm from the edge of the membrane. Sikaplan® G-18 is overlapped by 100 mm. The spacing of the fasteners is in accordance with the project specific Sika calculations. At upstands and at all penetrations, the membrane must be secured by additional fasteners and washers/tubes. The fasteners and washers/tubes protect the Sikaplan® G-18 roof covering against tearing and peeling off by wind uplift.

Hot welding method

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.

Testing overlap seams

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.
