do you do a spray paint that we can use directly onto galvanised steel or do i need to use a primer first
Assuming you are looking for an aerosol spray paint, the galvanised steel is clean, dry, sound and prepard as detailed in the technical data sheet unfortunately no, the area would need to be primed first.
If the area is not exposed to traffic or heat we can recommend Maston Spraypaint 2K Primer followed by Maston Spraypaint 2K Colours.
This can be mixed to many RAL , NCS colours in a matt, semi-gloss or high gloss finish.
