Painting tips for spraypainting your car

4. Grinding

Grind the even and hardened vehicle putty (drying time approximately 20-30 min.) by using dry grinding paper P120 or P180. Remove all grinding dust with a soft cloth.

5. Spread the anti-corrosion primer

In case the area has corrosion, use Rust Primer. Check that the area is free of metal, dust and grease. If needed, use Brake Cleaner for grease removal. Work the area with Rust Primer corrosion protection - spray primer. Note: Before painting, shake the can carefully for a minimum of 2 minutes.

6. Paint with acid primer or filler

You can level out irregularities with 1K Fyllprimer or filler. Spray several layers of 1K Fyllprimer/filler. Wait between the layers until the previous layer is surface dry. This way even the last pores are closed. 1K Fyllprimer/filler ensures a smooth basis for overcoat.

7. Final wet grinding

Grind the dried surface lightly with a wet paper P 400 or P 600 until the surface is even and thoroughly ground. Remove the fine dust particles. Let the surface to be fixed dry out completely.

4. Maintain spraying distance

Check correct painting distance, which is about 25 cm. A tip from professionals: you can influence the metal colour tone by spray technique. When the spraying distance is closer, the paint becomes ”more moist” and the colour tone will be darker. When the distance is greater, paint layer is ”drier” and the colour tone lighter.

5. Priming overcoat

Spray a very light paint overcoat during the first painting session. This gives the surface paint a good foundation and the next layer remains better fixed to the surface and prevents the next layer from running.

6. Priming smaller surfaces

Use a so called ”sablon” painting technique for smaller surfaces: Cut a hole into a stiff piece of cardboard, which is slightly larger than the area to be fixed. Keep the cardboard approximately 1-2 cm above the damaged area and spray from outward to inside direction. You will create fading, where the paint layer is thicker in the damaged area and thins out towards the edges.

7. Priming larger surfaces

Paint larger surfaces using the so-called crossing-technique. During the first painting session, you only paint a very thin layer. Keep the spray paint vertical and move it first from left to right and back, and then from up to down and back, in order to create a thin, non-covering crossing layer. Avoid an excessive layer thickness by always starting the painting from the outside of the area to be fixed, by moving the spray over the area to be painted only when it is evened out. Finally turn the spray away from the surface which is being painted and only then release the nozzle.

8. Final surface

Wait about 5-10 minutes between layers. Paint 2-3 layers until you have created a smooth and glossy surface.

9. Surface finishing with clearcoat

Metallic paints are always to be finished with a clearcoat; otherwise they do not achieve the final colour tone and shine. Wait about 5-10 minutes between layers. Spray the clearcoat for 2-3 layers until you have created a smooth and glossy surface. Also solid paints are recommended to finish with clearcoat. The glossy and wear resistant of the surface is increasing when overcoated.

10. Drying/surface grinding/polishing

The painted surface may be ground/polished at the earliest after 4 days has passed since painting. Please note that, prior to final drying, the painted surface is not resistant to solvents or heavy scrubbing and is at risk of suffer damage.
