The Benefits

Galvanised metal has a zinc coating that is designed to protect it from the weather; unfortunately, this coating makes it hard for conventional paints to stick to the surface and so a specialist primer is needed.

Galvanised metal surfaces can be found in a wide variety of industries with facilities such as factories and warehouses, garages and workshops, supermarkets, road and rail infrastructure including, but not limited, to:

  • Metal security fences and railings
  • Gates, including manual and automatic and sliding gates
  • Steel frames used in industrial units (factories, warehouses) and workshops
  • Roofing panels on commercial and industrial units
  • Roller shutter doors
  • Trimline and box gutters
  • Signal gantries
  • Storage containers
  • Bridges

Zinsser listens to contactors and develops new products – or adds features to existing products – to meet their changing needs, delivering world class products that meet “real world” challenges, providing tried and tested solutions to painting problems, such as painting galvanised metal.

Step 1. Surface Preparation

Start by removing all visible signs of organic growth from the galvanised metal surface and treat the affected areas with Zinsser Mould Killer & Remover, in accordance with the manufacturer’s instructions, and allow it to dry.

Clean the surface of contaminants and of anything that could affect and interfere with the application and adhesion of materials and Zinsser products.

Degrease overall with methylated spirit, frequently changing the cloth before priming.

Step 2. Priming

Use one full coat of Zinsser Bulls Eye 1-2-3 to prime all bare metal, in accordance with the manufacturer’s instructions, and allow a minimum of 1 hour drying time (in normal drying conditions) before decorating.

Step 3. Decoration

For interior projects, decorate the surface with two full coats of Zinsser Perma-White Interior in accordance with the manufacturer’s instructions and allow a minimum drying time of two hours between coats. Available in a Matt, Satin or Semi-gloss finish, Perma-White has a selection of more than 350 colours to choose from.

On exterior galvanised metal surfaces, use two full coats of Zinsser Allcoat Exterior Satin & Gloss and allow a minimum drying time of one hour between coats, in accordance with the manufacturer’s instructions. The coating is available in more than 350 colours with satin and gloss finishes.
