STEP 1

Heating Cartridge

Heating the product allows easy application at lower pressure and smooth texture. Pre-heat cartridges in the heating device (max. 60°C).
NOTE: Remove bottom lid from cartridge before heating.

STEP 2

Surface Preparation

Remove all contamination from the surfaces and pretreat the sealing area with TEROSON® VR 10.

STEP 3

Preparation Cartridge

Remove bottom cover and open cartridge. Screw on nozzle tightly.
Insert cartridge and adjust nozzle to working position. Horizontal or vertical application. Use the stabilising ribs for guidance during application.

STEP 4

Air pressure adjustment

Adjust main air pressure on supply unit to between 6 bar (min) and 10 bar (max).  Adjust application pressure on TEROSON® ET GUN POWERLINE II handle.

STEP 5a

Producing flatstream beads

To create a flatstream bead hold application gun at a distance of 6 to 12 cm from the surface. Adjust pressure to 6 to 12 bar with TEROSON® ET GUN POWERLINE II, depends on recommends width of OEM.

STEP 5b

Producing widestream beads

Before applying sealant, tape beginning and end of the application area. Remove the masking tape before the beads form a skin. Create a widestream bead (to reproduce acoustic applications) with a size of 8 to 12 cm in width, adjust the working pressure at 15 to 22 bar and distance the nozzle to surface of 8 to 12 cm.

Optional

Additional application  tools

There are different application tools that can simplify the application. E.g. the flexible hose allows you to work even in areas with minimal space. A  spacer can be used to keep equal distance to the surface or to guide along the edges.
