SUBSTRATE PREPARATION

Black steel sheet: microsandblast and sand.

Steel sheet: degrease carefully with 00695 SILICONE REMOVER SLOW, sand or sandblast.

Aluminium and light alloys: degrease carefully with 00695 SILICONE REMOVER SLOW, sand or rub down.

Electrolytic galvanised steel: degrease carefully with 00695 SILICONE REMOVER SLOW.

Hot dip zinc-coated steel: degrease with 00695 SILICONE REMOVER SLOW and sand or rub down.

Pre-existent coatings: do not apply on solvent-sensitive films. Degrease with 00665 HYDROCLEANER SLOW / 00699 HYDROCLEANER.

NOTE: The adhesion on aluminium alloys and zinc-coated steel sheets must be previously tested.
