B. Partial paint renewal
When large areas of "polyurethane series 07396" paint have to be repaired, a polyurethane paint of same kind must be used.
Perform the following operations :
- Careful sand with abrasive cloth (TB 05-916H).
- Cement scratches or aspect defects if necessary.
Filler (TB 08-904) sealant for big holes.
. Cellulose finish sealant for small layers.
- Dry sealants.
- Sand sealants.
- Apply a coat of primer (TB 16-532) with a stencil brush on sealants.
- Dry primer.
- Sand.
- Apply polyurethane finish paint with a heavy thinner to prevent dullness, i.e. dust on paint which may cause rings around repair area.
Should fine scratches, stains or pitting appear after chemical aggressions, the application of spray paints which bring glossiness and color, but in no case the same protection as polyurethane paints, may be used. However, the area to be repaired has to be sanded with abrasive cloth (TB 05-916H) to help paint adherence.
