We have a remedial redecoration job to manage in a retail are which suffered a small fire and has minor smoke mark the roof is insulated galvanised press steel panels looks ot be RAL 9010 or close - previously spray finished in manufacture however we cannot apply using spray as in a live retail environment what would be a cost effective appropriate paint for application by roller / brush ?
For brush or roller or airless spray application to these roof panels assuming the are clean, dry, sound and prepared as detailed in the technical data sheet we can recommend Zinsser AllCoat Interior (Solvent-Based).
This can be mixed to many RAL, NCS or BS colours in a matt finish.
