Preparation
Abrade Aluminium, Copper and Brass to improve adhesion. On aged, dull galvanised surfaces spot prime any corroded or oxidised areas where the galvanise has broken down with Hammerite No1 Rustbeater. On new, bright, galvanised surfaces, leave to weather for a number of months until duller and coarser before application of Hammerite Direct to Galvanised Metal Paint. For maximum protection and a longer lasting finish, apply 1 coat of Hammerite Special Metals Primer first. Where the surface has been previously painted, it is recommended that a small test area is applied. Leave for 1 hour. If there is a reaction remove all paint before applying Hammerite Direct to Galvanised Metal Paint.
Note: Special precautions should be taken to avoid inhalation of dust during surface preparation of pre-1960's paint surfaces as they may contain harmful lead.
