APPLICATION AND USE
Preparation
STEEL
Degrease with solvent, Super Cleaner or a suitable liquid detergent. Gritblast to Sa 2½ near white metal surface. If gritblasting is not possible, grind the metal surface with 2436 grit abrasive discs to a uniform, clean, bright metal surface with a 5075 microns anchor pattern. Use angle grinder on small areas.
ALUMINIUM
Degrease with solvent, Super Cleaner or a suitable liquid detergent. Sand well using 24120 grade (aluminium compatible) paper. Coarser grades are recommended to achieve optimum adhesion. Clean thoroughly and allow to dry. Prime using a recommended International primer as soon as possible (within 8 hours) as detailed for specific coating systems.
ZINC/GALVANISED STEEL
Degrease with solvent, Super Cleaner or a suitable liquid detergent. Sand well using 60120 grade paper. Clean thoroughly and allow to dry completely. Prime using a recommended International primer as soon as possible (within 8 hours) as detailed for specific coating systems.
STAINLESS STEEL
Light gritblast to produce a profile of 50 microns. Clean thoroughly and allow to dry completely. Prime using a recommended International primer as soon as possible (within 8 hours) as detailed for specific coating systems.
LEAD
Degrease with solvent, Super Cleaner or a suitable liquid detergent. Sand well using 120 grade paper or power wire brush Clean thoroughly and allow to dry. Prime using a recommended International primer as soon as possible (within 8 hours) as detailed for specific coating systems.
