FAQs
Can this primer be used on galvanized steel?
Yes, provided the galvanized steel surface is clean, dry, and suitably prepared. Light abrasion may be necessary to ensure adhesion.
What is the drying time for this primer?
The primer is fast drying. It is typically touch-dry within 1-2 hours and can be recoated after approximately 4-6 hours, depending on temperature and humidity.
How many coats of primer are recommended?
Typically, one or two coats are recommended, depending on the condition of the substrate and the desired level of protection. A second coat may be beneficial for heavily corroded or pitted surfaces.
Can I paint over this primer with any type of topcoat?
This primer is generally compatible with alkyd-based topcoats. It is always recommended to test compatibility with your specific topcoat in an inconspicuous area first.
What is the coverage rate of this primer?
Coverage varies depending on the application method and surface porosity, but it typically provides approximately 10-12 square meters per liter.
Does this primer require a separate topcoat?
Yes, while this primer offers excellent protection, it is designed to be used as a base for a suitable topcoat to provide a complete protective and decorative system.
Troubleshooting
Primer is too thick for application
Stir the primer thoroughly. If still too thick, thin slightly with white spirit according to manufacturer recommendations for the application method (brush, roller, or spray).
Poor adhesion to the surface
Ensure the metal surface was properly prepared (clean, dry, free from grease, rust, and loose paint). Abrade smooth surfaces before application.
Slightly uneven finish after drying
Apply the primer evenly. Lightly sand the dried primer surface with fine-grit sandpaper and apply a second coat if necessary for a smoother finish.
Rust reappearing after priming
Ensure all loose rust was removed before priming. The surface must be clean and dry. Apply a second coat of primer if needed.
