I'm building some interior stair balusters out of new, black mild steel bar and want a really good black statin finish. Please advise what products I would need for preparation and painting. So confused by self etching, enamel or direct to metal products. I know I will need to degrease but not sure about mill scale ?
Assuming the steel balusters are clean, dry, sound and prepared as detailed in the technical data sheet we can recommend one coat of Rust-Oleum 3369/3380 CombiPrimer Anti-Corrosion followed by two coats of Rust-Oleum CombiColor Original.
This can be mixed to many RAL, NCS or BS colours in a satin or gloss finish.
The millscale will need to removed prior to application, this could be done by mechanical abrasion.
