FAQs
What is the best surface preparation before applying this primer?
The surface must be clean, dry, and free from grease, oil, wax, rust, and loose paint. For best results, lightly sand the surface to ensure proper adhesion.
How long does the primer need to dry before sanding?
The primer typically dries to a sandable state within 30 minutes under normal conditions (around 20°C / 68°F). Drying time may increase in colder or more humid environments.
Can this primer be used on plastic parts?
Yes, this primer adheres well to most rigid plastics. Ensure the plastic surface is clean and degreased before application.
How many coats should I apply?
Apply 2-3 light, even coats for optimal coverage and build. Allow 5-10 minutes drying time between each coat.
What is the coverage of one 500ml can?
Coverage varies depending on the surface texture and application thickness, but a 500ml can typically covers approximately 1.5 to 2 square meters with a single coat.
Is this primer suitable for exterior use?
Yes, this primer is designed for use on automotive and general surfaces, providing a durable base for exterior topcoats.
How should I dispose of empty cans?
Empty aerosol cans should be disposed of according to local regulations. Ensure the nozzle is cleared of product before disposal.
Troubleshooting
Uneven spray pattern or spitting
Ensure the nozzle is clean. Shake the can more vigorously for at least two minutes before and during use. Turn the can upside down and clear the nozzle after use.
Primer not adhering to the surface
The surface may not have been properly prepared. Ensure it is clean, dry, and free from contaminants like grease, oil, or wax. Sanding the surface can also improve adhesion.
Runs or sags in the finish
Applying coats too thickly or too close to the surface can cause runs. Apply in thin, even coats, maintaining a consistent distance from the surface, and allow proper drying time between coats.
Clogged nozzle after use
Turn the can upside down and spray for a few seconds immediately after painting to clear the valve and nozzle. If the nozzle is permanently clogged, replace it with a new can.
Pros and Cons
Pros
- Provides a thick, filling layer to correct surface irregularities.
- Ensures good adhesion for subsequent paint layers.
- Convenient aerosol application for ease of use.
- Quick drying time speeds up the painting process.
- The grey color aids in visual inspection of the surface.
Cons
- Requires proper ventilation due to aerosol spray.
- May require sanding to achieve a perfectly smooth finish.
- Limited to 500ml cans, potentially requiring multiple cans for extensive jobs.
- Color is fixed to grey, which might not be ideal as a primer for all topcoat colors.
Setup, Compatibility & Care
Setup:
- Ensure the surface to be primed is clean, dry, and free from grease, wax, and dust.
- Shake the aerosol can vigorously for at least two minutes after the mixing ball starts to rattle.
- Test spray on a non-visible area to check for spray pattern and color.
- Hold the can upright, approximately 10-12 inches (25-30cm) from the surface.
- Apply in light, even coats, using a steady back-and-forth motion. Avoid applying too heavily in one area.
- Overlap each pass by approximately 50% to ensure even coverage.
Compatibility:
This primer is compatible with most automotive paints, including acrylics, enamels, and water-based finishes. It adheres well to bare metal, aluminum, primer fillers, and most rigid plastics. Always test compatibility on a small, inconspicuous area if unsure.
Care:
- After use, turn the can upside down and spray for a few seconds to clear the nozzle and prevent clogging.
- Store cans in a cool, dry place, away from direct sunlight and sources of ignition.
- Keep out of reach of children.
