How to paint galvanised metal

Galvanised metal has a zinc coating, designed to protect it from the weather. Unfortunately, normal paint doesn’t adhere very well to zinc, so you need a specialist primer.

Steps

1. Surface Preparation

Remove all visible signs of organic growth and treat the areas with an efficient mould killerin accordance with the manufacturer’s instructions. Allow to dry.

2. Priming

Ensure the surface is free from any contaminants and anything that could interfere with adhesion then degrease overall with methylated spirit frequently changing the cloth. Prime all bare metal with one full coat of Bulls Eye® 1-2-3 Primer Sealer in accordance with the manufacturer’s instructions. Allow a minimum drying time of 1 hour in normal drying conditions.

3. Decoration

For interior projects decorate with two full coats of Perma-White® Matt or Satin in accordance with the manufacturer’s instructions. Allow a minimum drying time of two hours between coats.
