Surface Preparation
Proper surface preparation is essential for achieving a flawless powder-coated finish. Here, we cover cleaning, degreasing, and pre-treatment methods that ensure long-lasting adhesion.

Why is surface preparation important for powder coating?
Proper surface preparation ensures the powder adheres correctly and forms a uniform, defect-free coating.
It prevents corrosion, peeling, and imperfections, improving the longevity and appearance of the finish.
What is degreasing and why is it necessary?
Degreasing removes oils, dirt, and residues from metal surfaces before coating.
Without degreasing, powder coatings may not adhere properly, leading to defects or flaking.
How does vapour degreasing work?
Vapour degreasing uses heated solvents in a vapour phase to clean metal surfaces.
It penetrates crevices, removes contaminants efficiently, and prepares parts for coating.
What is an aqueous wash cleaning process?
Aqueous washing uses water-based detergents and mechanical agitation to remove dirt and oils.
It is safe, environmentally friendly, and suitable for large-scale pre-treatment.
When is immersion wash cleaning used?
Parts are submerged in cleaning solutions to remove heavy contaminants or complex geometries.
It ensures consistent cleaning of intricate or hard-to-reach areas.
How effective is solvent wiping for metal preparation?
Solvent wiping is suitable for small parts or spot cleaning but is less thorough than degreasing baths.
It can be a quick solution but may leave residues if not performed carefully.
What is phosphating and how does it help powder coating?
Phosphating creates a chemical conversion layer on metal that improves adhesion and corrosion resistance.
It is commonly used on steel before powder coating to enhance coating durability.
How does chromating improve adhesion on aluminium?
Chromating forms a thin protective layer that promotes bonding between aluminium and powder coatings.
It also provides corrosion protection, particularly in outdoor environments.
What common mistakes occur during surface preparation?
Common errors include insufficient cleaning, oily residues, inconsistent pre-treatment, and missed contaminants.
These issues often result in poor adhesion, defects, or premature coating failure.
How do I prevent rust or corrosion before powder coating?
Clean and degrease all metal surfaces, and store them in dry, dust-free conditions before coating.
Applying pre-treatment like phosphating or chromating further prevents corrosion.
