∎Direction for use

 

Tool: Manual or pneumatic plunger caulking gun

●Cleaning: Clean and dry all surfaces by removing foreign matter and contaminants such as oil dust, grease, frost, water, dirt, old sealants and any protective coating.

●For cartridge

1.Cut nozzle to give the required angle and bead size

2.Pierce the membrane at the top of the cartridge and screw on the nozzle

3.Place the cartridge in an applicator gun and squeeze the trigger with equal strength

●For sausage

1.Clip the end of the sausage and place in barrel gun

2.Screw end cap and nozzle on to barrel gun

3.Using the trigger extrude the sealant with equal strength

●Apply Maxtech PU Sealant

 For Automotive Car Windscreen/Windshield in a continuous bead using constant pressure to apply the sealant
