SURFACE PREPARATION AND APPLICATION

New Mild steel

1. Use Paintcor’s GrimeReaper to remove all grease and oil from the steel to be primed (see GrimeReaper Data sheet).
2. Sand or shot blast all steel back to bright metal (removing all mill scale and rust). Remove all sanding dust.
3. Apply 2 coats of AllPrime Plus (1 coat for highveld conditions). Allow at least 60 minutes at 25°C to dry between coats.
4. Do not apply the coats too thick, AllPrime Plus is a wash primer and should not obliterate the surface it is applied to. Apply thin coats.

New Galvanised iron

1. Use Paintcor’s GrimeReaper to remove all grease and oil from the galvanized iron to be primed (see GrimeReaper Data sheet). Allow to dry.
2. Remove all white or red rust from the galvanized iron surface, if any. (White rust can be removed by washing the galvanized sheeting thoroughly with undiluted white spirit vinegar). Rinse well with water after washing and allow to dry.
3. Apply 1 coat of AllPrime Plus and allow at least 60 minutes at 25°C to dry between coats.
4. Do not apply the coat too thick, AllPrime Plus is a wash primer and should not obliterate the surface it is applied to. Apply thin coats
