For other applications, tests with actual substrates and conditions have to be performed to ensure adhesion and material compatibility.

Surfaces must be clean, sound, dry and free from all traces of traditional and non-traditional contamination. All corrosion must be removed and all bare metal scrapes and scratches must be prepared in accordance with Sika's Corrosion Treatment recommendations. Windshields without ceramic coating need proper UV protection. This adhesive requires a primer to bond properly.

Cut off the tip of the nozzle in accordance with the vehicle manufacturer’s recommendations and screw onto the cartridge or the unipack adapter. It is recommended to apply the adhesive with a piston-type application gun. To ensure a uniform thickness of adhesive bead, the manufacturer recommends that the adhesive be applied in the form of a triangular bead.
