How to Properly Prepare Metal Surfaces: Zinc Phosphate Primer + Crown Aluminium Paint Guide

When it comes to painting metal surfaces, proper preparation is what separates a temporary fix from long-term protection. Whether you’re dealing with gates, roofs, tanks, or metal structures, the combination of Crown Zinc Phosphate Primer followed by Crown Aluminium Paint is one of the most effective systems for preventing rust and corrosion.

At Rangi Paint Store, we stock both products from Crown Paints Kenya—trusted by professionals across the country for their quality and durability.

🧰 Step 1: Surface Preparation

Before applying any paint, ensure the metal surface is clean, dry, and free from rust, oil, or loose material. Use a wire brush, emery paper, or sandblasting for best results. Wipe the surface with thinner or a clean cloth to remove grease or dust.

A properly cleaned surface ensures better primer adhesion and prevents flaking later on.

🧴 Step 2: Apply Crown Zinc Phosphate Primer

Zinc Phosphate Primer is a high-performance anti-corrosive coating designed to protect metal surfaces from rust. It works by forming a strong barrier between the metal and moisture, preventing oxidation and corrosion.

• Key Benefits:
  • Excellent rust protection
  • Strong adhesion to bare metal
  • Ideal for steel structures, roofs, and iron sheets
  • Fast-drying and easy to apply

Apply one or two coats of Crown Zinc Phosphate Primer evenly using a brush, roller, or spray gun. Allow it to dry completely before moving to the next step.

🎨 Step 3: Finish with Crown Aluminium Paint

Once the primer is dry, apply Crown Aluminium Paint as the finishing coat. This paint contains real aluminium flakes, providing a bright, reflective metallic finish that enhances both appearance and protection.

• Why Choose Crown Aluminium Paint:
  • Heat-resistant and weatherproof
  • Excellent for roofs, tanks, pipes, and gates
  • Reflects sunlight, keeping metal surfaces cooler
  • Long-lasting shiny metallic finish

This two-layer system—Zinc Phosphate Primer + Aluminium Paint—is the perfect defense against rust, moisture, and UV damage, ensuring your metalwork stays protected and looking good for years.
