STEP 1

Preparation Cartridge

Remove bottom cover and open cartridge. Screw dispensing nozzle (inner nozzle) onto cartridge.

STEP 2

Screw on second part of spray nozzle

Insert the cartridge into the spray gun and screw on blue screw cap. Attach second part of spray nozzle on top.


STEP 3

Using the air gun

Adjusting the compressed air gun and the screws — the supply pressure must be at least 6 bar (max. 10 bar). Start the closed sealant flow and open air flow completely. Position gun towards the substrate and press trigger. Slowly open sealant flow to get base structure (different ratios of sealant and air supply will produce the required texture).

STEP 4a

Spray seam sealing

Hold the nozzle in the vertical position and move at a right angle to the seam about 4 cm above the surface. In case of overspray adjust distance. Let the product cure.
