Surface Preparation Options
Three-Stage Chemical Treatment (for clean steel, galvanized steel, stainless Steel and aluminium)
Recommended when steel is already cleaned and ground with no rust.
This process improves adhesion and corrosion resistance:
-
Phosphate Wash – Optimal bonding layer for steel, galvanised steel and aluminium.
-
Rinse – Ensures the surface is perfectly clean and free of contaminants.
-
Passivate – Seals the surface to prevent flash rust and increase coating life.
Sandblasting (for large, rusted or previously coated steel)
Abrasive blasting removes rust, paint and contaminants while creating a perfect surface profile for powder coating.
Ideal for heavy steel components, outdoor steelwork, and restoration projects.
