4.

Grind polypropylene surface carefully. It melts easily due to the heat generated by friction. If melted, remove that area.
Also, grind the area where solvent is to be applied.

5.

Apply polypropylene primer evenly with a brush over an area wider than the area to be repaired.
Dry it at 20 C (68 F) for more than 10 minutes.

6.

Mix main filler material and hardener at a ratio depending on paint specifications. Mix filler material and apply over the
damaged area.

NOTE

•

Mix main filler material and hardener so that no bubbles are made.

•

Work immediately after mixing filler material because the filler material hardens quickly(in about 5 minutes).

•

Dry it at 20 C (68 F) for about 30 minutes before sanding.

•

Filler material consists of two types of epoxy.
When the filler material hardens, you will have a desirable finish with flexibility like polypropylene.

•

Use only filler material designed for use on polypropylene bumpers.

Do not grind continuously.

7.

Sand the damaged area with sandpaper using #180~#240 grit paper.

NOTE

•

The surface will not be even if excessive force is applied during sanding.

•

If there is fuzz in the damaged area, heat it a little bit with a heater gun and melt it.

8.

Degrease the painted surface.

9.

Mix polypropylene primer and hardener at a ratio depending on paint specifications.
Spray polypropylene primer on the surface of the damaged area and the bumper.

10. Apply polypropylene primer.

NOTE

Use only water to clean after applying polypropylene primer. Solvent, if used, will melt the primer.

11. Lightly sand the sprayed area using a primer a sandpaper(#400~#600).

The polypropylene surface should not be exposed.(Either wet sanding or dry sanding is all right.)

12. Use agent(TCE(Tri Chloro Ethane) degreasing material) to remove any grease or oil, and wipe the finished surface of the

bumper quickly with a clean cloth.

NOTE

•

The painting method for the polypropylene bumper is the same used to paint the urethane bumper.

•

Therefore, use urethane primer only on urethane bumpers and polypropylene primer on polypropylene bumpers.

13. Air dry at 20 C(68 F) for about 8 hours, or dry in 60 C(140 F) for about 2 hours.

(Since drying time varies according to the type of paint used, follow paint manufacturers directions for drying times.)

NOTE

Air dry if possible. Forced drying may create air bubbles on the top layer.
