general notes

Color checking 

Color checking is required before painting of cars with all refinish systems. 

1.Prior to checking look up the motor manufacturer’s color code and color name in the Roch color tinting system to find the color formulation.

2.Prepare test panels. 

Apply Kapci basecoat to the test panels to give opacity. The basecoat is normally applied in 2 coats (for metallics apply one mist coat as per given the application procedure) but some colors require more coats. After recommended flash off time apply Roch 2K clearcoat and identify the color which most accurate matches with the car. 

3. For three-stage basecoat colors use at least two test panels and firstly apply ground basecoat color. Then apply pearlescent and special effect pigment basecoats color over the test panels to identify the number of coats required to achieve the most accurate color, e.g. apply 2 coats over the first panel, 3 coats to the second test panel, etc. After required flash off time apply Roch 2K clearcoat to compare which the test panel color matches the car. 

Important Notes: 

 Pearlescent and special effect pigment basecoat colors are transparent hence they do not cover. 

 With low opacity colors it may be necessary to apply a coat more after the appropriate flash off time. Use appropriate shade of Roch 2K grey fillers before applying the basecoat. 

 Maximum dry film thickness for three-stage colors for 4 coats is approximately 40 microns. 


Visible defects can be removed only after the basecoat is fully dry by light manual sanding with paper P1500 or finer. For smoother sanding, the sanding paper can be slightly soaked with water.
