UK Best Undercoat Paints & Metal Primers

Metal primer and undercoat paints are liquid products containing rust inhibitive pigment resin and zinc. The primary purposes of these products are reducing the coating porosity and improving the adhesion and the anti-corrosion functions of the painted surface. Thus, the correct approach to painting involves the primer application for the bottom layer to preserve the top layers' protective and decorative properties.

Industrial Metal Primer Paint for Long-Term Protection

Primer undercoat paint defines the protection level of the finish coating for metal surfaces. It contributes to the excellent adhesion of the protective layer and the painted buildings. Moreover, metal primer paint such as our Red Oxide Primer has another essential function – protection against corrosion and rust, provoking natural material destruction. The resulting layer also has to withstand heavy-duty loads to extend the lifespan of the painted object.

The right use of industrial primer for metal is essential to minimise cover breakdown. You can use specific galvanised undercoat paints or purchase all-in-one metal primer. Paints4Trade professionals are always ready to help you choose undercoat products, depending on individual needs and preferences. 

How to Paint Surface with Undercoat Paint for Metal

After choosing undercoat paints, you can proceed to surface treatment. Check the existing coating and remove it. Eliminate rust, grease, and other contaminants from the surface. Apply primer undercoat paint in a few thin layers using a roller, brush, or spray. Glossy finishes sometimes need extra abrasive processing for better adhesion to the topcoat. The drying time of undercoat paint for wall is several hours. Nevertheless, we recommend applying the overcoating layer after 16-24 hours for long-lasting results.
