Corroless G is a single pack, easy to apply coating, containing Micaceous Iron Oxide (MIO) for excellent durability and adhesion. It can be applied to new or weathered galvanising without the need for an etch primer. For application as a top barrier coat over steelwork, a suitable Corroless primer should be applied first. Typical applications for Corroless G3 include street furniture, galvanised gates, railings and fencing.
