🟢 For this tutorial we will use the Nardo Grey colour code used on this Audi Q2 as an example. Let us take a look at the steps to be performed.
Identifying the colour
First, use a spectrophotometer to measure the colour of adjacent areas.
Choose the right colour version in the software.
Intermediate coat optimisation
To optimise the colorimetry of the repair, the system's software will provide the ideal colour shade of the filler to obtain an excellent coverage, avoiding the need to apply more layers than those required.
Application of the colour coat
The colour coat is formulated following the software instructions.
Subsequently, adjust the viscosity of the paint depending to the temperature and relative humidity there is at that time. The dilution may range from 15 to 35%.
Regulate the gun based on the product's technical data sheet.
Apply a first anchorage coat.
For this repair, use the blending technique, extending the product towards the limits of the part from inside to outside, in order to favour the integration of the repair.
A second, more even, extended and regular coat over the entire surface, without applying excessive product on the edges.
An additional tip and optional step, to ensure an even better integration of the repair, can be to apply an integrating additive specially designed to optimise the colour transition in blending processes such as the one in this example.
Prepare the mixture and apply it over the entire repaired surface.
This will prevent the appearance of halos or marks at the edges of the patch, which are typical in this types of solid grey colours.
Next, the effect coat, which will serve to integrate the application evenly.
Application of the clear coat
Finally, apply the final high-performance clear coat.
Apply two regular and uniform layers over the entire surface, providing extra chemical and mechanical resistance to the part.
Following all these steps will lead to achieving a repair with excellent matching in solid grey colours.
