Spot Prime
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.
