I want to paint the edges of 5 external galvanised stairs. Do I need a primer for the galv? if so which one? Which none slip product would I then use for the final coat.
Assuming the galvanised stairs are bare, clean, dry, sound and prepared as detailed in the technical data sheet including the use of Teamac Mordant Solution (T Wash) you could consider Coo-Var Zinc Phosphate Primer followed by Coo-Var Suregrip Anti-Slip Floor Paint.
This is available in a range of colours.
