Step 1: Surface Preparation

Cleaning: Ensure the surface is clean, dry and free from grease, dust and any contamination. Use a suitable degreaser to remove all traces of dirt and grease.

Correcting defects: In case of deep scratches, dents, or other defects , apply a suitable putty to obtain a uniform surface.

Sanding: For optimal preparation, use the following sandpaper grits:

  • P400 grain to remove imperfections and even out the surface.
  • P600 grain to smooth further and prepare for the primer coat.
  • P800 grain for a perfectly smooth finish.

Thoroughly wet the body and paper with water.

Final cleaning: Remove all dust and sanding marks and ensure the surface is completely clean before applying the primer.

Step 2: Application of the 1K Universal Primer

Spray preparation: Shake the spray vigorously for at least 2 minutes to mix the product well.

Primer application: 1K Colormatic primer undercoat

  • Hold the can about 20 cm from the surface.
  • Apply a first thin coat with a simple back and forth motion, then let dry for 3-4 minutes to avoid dripping.
  • Apply a second, slightly heavier coat , crisscrossing the strokes for even coverage.

Drying time: Allow the primer to dry for at least 30 minutes before moving on to the painting stage.

Step 3: Applying Body Paint

Spray preparation: Shake the spray paint well for 2 minutes.

Spray Test: Do a test spray on a control surface to check color and flow.

Paint Application: Custom Body Spray

  • Hold the can about 20 cm from the surface.
  • Apply a first thin coat in a simple back and forth motion, then let dry for 3-4 minutes to avoid dripping.
  • Apply a second, slightly heavier coat , crossing the strokes to obtain a uniform shade.

Drying time: Wait approximately 30 minutes before moving on to the next step.

Step 4: Application of 1K Clear Varnish

Preparing the varnish: Shake the varnish can for at least 2 minutes.

Application of varnish: 1K Colormatic varnish

  • Hold the can about 20 cm from the surface.
  • Apply a first thin coat in a simple back and forth motion, then let dry for 3-4 minutes.
  • Add a second, slightly heavier coat for a smooth, glossy finish.

Final drying: Leave to dry for at least at least 24 hours to allow the varnish to harden and withstand handling.

Application of Tri-Layer Tints

For some body colours, a three-layer process is necessary to achieve a unique depth and shine effect:

  • Base Tint : Provides the background color.
  • Semi-transparent layer : Contains glitter for a metallic or pearly effect.
  • Colorless lacquer : Provides shine and protection.

Note: This process usually requires professional application to ensure proper color accuracy. If you wish to do it yourself, purchasing an additional tri-coat tint spray is required.
We will notify you if this option is required for your color, with always the option of obtaining a refund if this operation seems too tedious for you.

Despite our efforts, we cannot guarantee a perfect color match for tri-coat shades with spray application.
