Recreating surface structure on bumpers, spoilers and scuff plates

Recreating surface structure on bumpers, spoilers and scuff plates


This procedure allows you to recreate the structure of visible unpainted surfaces after welding and sanding. This method can also be used to repair light and very superficial scratches

Note

Always use a gravity feed spray gun with the recommended nozzle (1.8 - 2.4 mm).

HVLP sprays also provide good results.



1. Sand the damaged area with abrasive paper (grade 400 - 500).


2. Clean the part with Teroson FL cleaner.

3. Mask the part so that only the damaged area is visible.

4. Start by priming the damaged area with two layers of a surface structure treatment mixture.

Mixture:

70% Terotex 3000 (white or black)

20% 2K paint

To maintain durability, 2K paint must always be used, even for black or white products.

10% Standard curing agent (suitable for paint), but not MS type.

5. Allow to dry and sand if required.

6. “Shower” carefully with the mixture. If a coarser structure is desired, lower the spray pressure and hold the spray gun at a greater distance. If a finer structure is desired, increase the spray pressure and hold the gun closer.


7. Place the part in a paint oven at 60°C, so that the structure sets.






Useful tips; The mixture can also be used to “raise” small plastic burrs on sanded surfaces. The part can be cured in an oven at 60°C and then rubbed with an abrasive cloth, Scotchbrite or the like.
