Top 5 Galvanized Steel Paint Primers You Need to Know About


When it comes to painting galvanized steel, not just any primer will do. You need a product that’s specifically designed to adhere to the zinc coating, while also providing a surface that your paint can cling to. In this post, we’ll delve into the top 5 galvanized steel paint primers (สีรองพื้นเหล็ก, which is the term in Thai) that you need to know about.

Why a Special Primer for Galvanized Steel?

You might wonder, “Why can’t I use any primer?” The answer lies in the nature of galvanized steel. Its anti-corrosive zinc coating makes it difficult for most primers and paints to adhere effectively. Using a specialized primer ensures that your paint job not only looks great but also lasts a long time.

What to Look For

Before we dive into our top picks, let’s quickly go over what you should look for in a galvanized steel paint primer:

  • Adhesion: It should have excellent bonding capabilities.
  • Durability: Look for a primer that resists peeling and flaking.
  • Ease of Use: Ideally, it should be easy to apply with a brush or roller.
