Thoroughly wash the bumper surface with lukewarm water and detergent, then degrease it with the in-process silicone remover PLUS 780, which effectively removes residues of grease, oil, silicones and other contaminants.
Protect the surrounding area and any parts not requiring repair with masking paper.
Sand the damaged area with P180-P240 abrasive paper.
Blow off the surface and degrease it again with the in-process cleaner PLUS 780.
If the repair area requires filling (e.g. deep scratches), apply a putty designed for plastics: BUMPER FIX or BUMPER FIBER (with glass fibre), both of which provide very high flexibility and excellent adhesion to most plastics.
Once the putty has fully cured, sand it with abrasive paper, reducing the grit sequence: P180 – P280 – P320.
Blow off the surface and degrease it with the in-process cleaner PLUS 780.
Apply PLASTIC PRIMER adhesion promoter to areas sanded through to bare plastic.
- mix the primer thoroughly by shaking the can for at least 2 min
- apply 1-2 coats (flash-off time between coats: 5-10 min)
- drying time: 15 min/20°C
- clean the nozzle for 5 sec by turning the can upside down
