Installation and usage advice

Before use, check that the cartridge is compatible with the gun format. Cut the nozzle according to the desired joint width, then insert the cartridge correctly into the semi-open holder. Operate the handle progressively to extrude the product evenly. For a neat finish, it is advisable to work on a clean, dry and dust-free surface. After use, release the pressure and immediately clean any residue on the tool in order to prolong its service life.

For sealing applications around windows and doors, it is recommended to adapt the bead width to the substrate and the type of sealant used. A continuous and controlled application makes it possible to obtain an even joint, limiting gaps, excess thickness and reworking.
