Application process


For filling small scratches during car body repair and isolate acrylic coatings from polyester putties.

Mixing ratio by volume

Spraying filler: 100
Hardener: 6
Thinner max: 35%

Stir thoroughly until obtaining a homogenous mixture.

Spraying viscosity

about 50 seconds at 20°C

Pot life for the mixture

about 20 sminutes at 20°C

Number of layers

1÷3 layers
Gun parameters
Nozzle: 1,8÷3,0 mm
Pressure: As recommended by the equipment manufacturer, usually 2.0 ÷ 2.5 bar.
Coating thickness
Do not exceed a thickeness of 200 µm for a single wet layer. Do not exceed the total thickness of 600 µm.

Flash off time

Between layers: 5÷10 min
Before baking: about 10 minutes

Flash off time depends on the temperature and coating thickeness.

Drying time

2-3 hours at 20°C.
25-30 min. at 60°C.

Temperatures below 20°C significantly increase the drying time.


Finish sanding (dry): P180÷P320.

IR drying

5÷7 min. under short waves, depeding on the total layer thickeness (up to 200µm) and type of radiator
Do not exceed maximum temperature of 60°C.
Use according to the instrusctions of the radiator's manufacturer.
Wait about 5 min. before starting IR drying.


1 liter of the mixture is enough to paint about 8 m2 of surface with a layer thickness of 100 µm.
