Surface preparation Abrasive blast clean to AS1627.4 Class 2 minimum. OR: Remove all scale, rust, old and flaking paint etc using a wire brush or mechanical means. All surfaces must be thoroughly degreased with HiChem Prepwash. All surfaces must be dried and primed as soon as possible after cleaning. When applying to non-ferrous surfaces such as galvanised iron, zinc/alum or aluminium apply a thin coat of HiChem Super Etch Primer. Application By spray only - conventional or airless. Apply 2-3 medium coats to produce the required build. Minimum dry film build 25 micron is recommended. Thinning Conventional spray gun: May be thinned up to 50% with HiChem Enamel Thinner E250. In hot conditions (say greater than 30C) use HiChem Mineral Turps. Airless spray equipment: Thin up to 15% with HiChem Enamel Thinner E250. In hot conditions (say greater than 30C) use HiChem Mineral Turps.
Drying time Surface dry: 10-15 mins depending on temperature and build Touch dry: 40-50 mins depending on temperature and build Re-coat after 1 hour with conventional enamels such as HiChem Quick Drying Spray Enamel.
