Pre-Treatment Before Powder Coating: Why It Matters

The best powder coating will fail prematurely on a poorly prepared surface. Pre-treatment is the single most important factor in long-term coating performance.

Shot Blasting

Removes mill scale, rust, and old coatings while creating a surface anchor profile. Recommended for structural steel.

Zinc Phosphating

Creates a crystalline zinc phosphate conversion layer that dramatically improves corrosion resistance and adhesion. Standard for furniture, appliances, and automotive.

Chromating (Aluminium)

QUALICOAT-certified pre-treatment mandatory for architectural aluminium applications.

Standards

Indoor: Degrease + Iron Phosphate
Outdoor: Degrease + Shot Blast + Zinc Phosphate
