Powder coating suits metal parts that fit in the oven and need a durable, even finish. Two pack spray paint suits timber, items too large for the oven, and jobs specified in an epoxy, polyurethane, chemical resistant or marine grade system. Advance Sprayers does both in one workshop in Richlands, so we recommend the one that suits the job.
How powder coating works
Powder coating is a dry finishing process. Electrostatically charged particles of pigment and resin are sprayed onto metal that has been electrically earthed, so the powder is drawn to the surface. The item then goes into a curing oven, where the powder melts and fuses into a durable finish that resists chipping, scratching and fading.
How two pack spray painting works
Two pack paint is mixed from two components and sprayed. The gun atomises the paint into a fine mist, for a smooth, even coat without brush marks or streaks. The surface is cleaned and primed first, and the coating is built up in layers to the finish the job needs.
When powder coating is the better fit
- Steel and aluminium parts that fit our ovens, up to 7.5 m long
- A choice of gloss, satin or matt; smooth, textured or ripple effect; epoxy or polyester
- A zinc-shield option for extra corrosion protection
- A Dulux warranty, which only an accredited powder coater can issue
When two pack is the better fit
- Timber, which we finish in two pack
- Items too large for our ovens, through to communication towers and light poles
- Specifications that call for two pack epoxy, polyurethane, chemical resistant or marine grade coatings
- Jobs painted to specification with quality assurance reports and documentation
What both need
Neither finish is better than the surface under it. Steel is sand blasted and coated within four hours, the limit the Australian Standard sets. Aluminium is chromated before it is powder coated.
Do you have to sandblast before powder coating? Can you powder coat aluminium?
How to decide
Tell us the material, the size of the largest item, the quantity, the finish you want and any specification. If a specification names a coating system, we follow it. If it does not, we will recommend powder or paint and say why.
