Johnstone's Trade Quick Dry Zinc Phosphate Primer - Grey - 5L

This primer is specifically designed for use on steel and other ferrous metal surfaces to provide anti-corrosive protection.

The drying time depends on environmental conditions, but it is formulated to be quick-drying, significantly reducing recoat times.

No, this is a single-pack primer, meaning it is ready to use straight from the container after stirring.

While the primer provides protection, it is intended to be overcoated. A topcoat is necessary for full durability, UV resistance, and the desired final appearance.

Brushes and equipment should be cleaned immediately after use with appropriate thinners to prevent the product from drying on them.

Yes, its anti-corrosive properties make it suitable for outdoor steel applications when properly topcoated.

The grey colour serves as a neutral base. It generally does not significantly affect the final colour of most topcoats, but lighter colours might require an extra coat for full opacity.

Ensure application in recommended temperature and humidity conditions. Thick application can slow drying; apply in thinner coats if necessary.

Verify that the steel surface was adequately prepared (clean, dry, free of rust and grease) and that the primer was thoroughly stirred.

This indicates inadequate surface preparation or a breach in the coating. Ensure all rust was removed prior to priming and that a consistent coat was applied. Apply a second coat if necessary, or ensure the topcoat provides adequate protection.

This can happen if the lid is not sealed tightly. Carefully remove the skin and stir the remaining product. To prevent future skinning, ensure the lid is properly sealed after each use and store the can upright.
