Installation and usage advice

Before use, check the compatibility of the cartridge with the gun format. Cut the cartridge nozzle according to the desired joint width, then pierce the seal if necessary. Insert the cartridge correctly into the semi-open holder and operate the trigger progressively to obtain a steady flow. For a clean result, it is advisable to work on a dry, clean and degreased surface.

When applying on doors, windows or glazing, maintain a constant angle and move at a steady speed in order to obtain a uniform bead. After use, release the pressure and clean product residues immediately before drying. Storage in a dry place helps preserve the mechanism in good condition.
