Introduction to Cold Galvanising Primers

Cold galvanising primers, such as Rustbuster Cold Galvanising Paint, are highly effective solutions for protecting steel surfaces from corrosion. These one-component epoxy primers contain high zinc content, often around 90%, which offers superior anti-corrosive protection. These primers are especially useful for repairing two-component zinc epoxy and zinc silicate coatings, making them an essential tool in maintenance and restoration projects.

How Cold Galvanising Primers Work

When applied to properly prepared steel, the high zinc content acts as a sacrificial anode. This means the zinc corrodes in place of the steel, providing ongoing protection. For example, if the paint scratches or chips down to the steel surface, the surrounding paint reactivates and corrodes sacrificially, protecting the exposed steel from rust and degradation. This self-healing property makes cold galvanising primers especially reliable in environments where the substrate may suffer damage or face harsh conditions.

Benefits of Cold Galvanising Primers

The benefits of cold galvanising primers extend beyond just repair—they also create a durable, long-lasting protective layer that significantly improves the lifespan of steel structures. By applying a cold galvanising primer like Rustbuster Cold Galvanising Paint, you ensure that the steel remains safeguarded against corrosion, even in extreme environments.
