Uses

Heavy duty zinc-rich primer for the protection of steel against corrosion in corrosive environments. Generally used as part of a protective coating system in: bridges and infrastructure, bulk handling equipment, chemical plants, commercial developments, coastal structures, exposed pipelines, high rise apartments, mining, offshore structures, oil refineries, power generation plants.

Surface preparation

Round off all rough welds and sharp edges, and remove weld spatter. Degrease by detergent wash according to AS1627.1. For all structural and decorative steel, abrasive blast clean to AS1627.4 Class 2.5. Remove all dust. Apply first coat before surface deterioration occurs.
