Q: Can you powder coat patio tube/pre galv material that has white powdery surface corrosion on it ?
A: Yes – But we do not recommend doing this, as the corrosion process has started on the steel, even after acid cleaning, sanding and priming, the final powder coat finish can bubble and corrosion can continue to manifest in the substrate over time. We offer no warranty against this and always recommend you use the very best clean substrates available for maximum protection and a quality surface finish.
Q: Can you powder coat just one coat over blue coated or black/mild steel?
A: No – Both require sand blasting prior to powder coating with Dulux Zinc Shield and re sprayed with Dulux Top Coat. Where ever possible always try and use pre galv steel instead of blue coated or mild steel which if not prepared and powder coated to spec will corrode within 6 months in an outside environment. The blue coating is only a painted transport coating and offers no corrosion protection what so ever and must be removed prior to powder coating.
