When working with metal surfaces — gates, grills, roofing sheets, tanks, machines, or structural steel — choosing the right primer is crucial. At Rangi Paint Store, Nairobi’s premium paint shop, we stock a variety of high-quality metal primers that protect, preserve, and help your top coats last longer. We also deliver countrywide.
Below is an in-depth guide to metal primers we carry, what makes them good, and how to choose the right one for your project.
🔍 What Is a Metal Primer & Why It’s Essential
A metal primer is a base coat applied to metal before you apply the final paint. Good metal primers:
- Prevent rust and corrosion
- Improve adhesion of enamel, gloss, or decorative topcoats
- Seal and prepare the metal surface so paint doesn’t peel or flake
- Help your topcoat look smoother and last longer
Without primer, metal surfaces are vulnerable to moisture, oxidation, and even peeling paint — especially under Kenya’s weather conditions, where humidity and rains accelerate rusting.

🛒 How to Choose the Right Metal Primer
Here are factors to consider when selecting a metal primer:
- Rust Prevention Requirement
If the metal is already rusted or exposed to moisture often, go for something like zinc chromate or primers with rust-inhibiting ingredients. - Type of Metal
Ferrous metal (iron, steel) rusts easily; aluminum, stainless steel require different products or treatments (etch primers etc.). - Environmental Exposure
If outdoors (rain, sun, humidity), you need primers that resist UV, water ingress, temperature changes. - Final Paint/Finish
Some primers are better paired with certain paints (e.g., enamel, gloss, or water-based top coats). Check compatibility. - Drying Time & Ease of Application
For fast jobs, faster drying primer helps. Sprays or brushable ones make corners, edges easier. - Colour & Coverage
Grey or red oxide primers are common — choose one whose undertone works well with your final finish (e.g., grey under light colours).

✅ How to Apply Metal Primer Correctly
To get the best results, follow these steps:
- Clean the metal surface — remove rust, grease, dust. Use wire brush / sandpaper.
- Wipe clean and dry completely. Moisture under primer causes early peeling.
- Apply a thin, even coat. Let it dry fully — refer to product instructions (some need several hours).
- Lightly sand if required before applying top coat, especially if surface feels rough.
- Apply your final coats of paint for protection and aesthetics.
