Product Information
Full details
The Pro Range Acid Etch Primer is an essential tool for professional painters and metalworkers looking to ensure long-lasting paint adhesion on difficult substrates. This trade-grade aerosol provides a high-performance chemical etch that bites into metal surfaces, creating a robust base for topcoats. While it offers superior rust protection and bonding strength, users must exercise caution due to its chemical nature, ensuring proper ventilation and skin protection during application.

Extended Product Information
FAQs
Can I use this primer on plastic parts?
No, this is an acid etch primer specifically designed for metal surfaces. Plastic requires a dedicated plastic adhesion promoter.
How long should I wait before painting over this primer?
You can typically overcoat with your chosen paint system after 30-60 minutes, though this depends on local humidity and temperature.
Does this product stop existing rust?
It is designed to prevent rust on clean metal. If rust is already present, you must mechanically remove it via sanding or sandblasting before application.
Is the finish water-resistant?
Once fully cured, it provides a stable, weather-resistant base layer, but it should be covered with a topcoat for permanent outdoor exposure.
What safety equipment do I need?
You should use a high-quality organic vapor respirator, nitrile gloves, and safety goggles to protect against fumes and overspray.
Troubleshooting
Spray nozzle is clogging during use
Wipe the tip of the nozzle with a solvent-dampened cloth or replace with a spare aerosol nozzle.
Paint finish appears grainy or rough
Ensure you are spraying from the correct distance (20-30cm); holding the can too far away causes the particles to dry before hitting the surface.
Poor adhesion to the metal surface
The metal was likely contaminated with grease or oil; strip the surface and clean thoroughly with a professional grade degreaser.

Setup, Compatibility & Care
To prepare the product, shake the canister vigorously for at least two minutes until the mixing ball rattles freely. The product is highly compatible with most automotive paints, including basecoat/clearcoat systems and enamel topcoats.
Care instructions:
- Always clear the nozzle after use by turning the can upside down and spraying for 3 seconds.
- Store the canister in a cool, dry place away from direct sunlight.
- Ensure the workspace is well-ventilated; using this product in a confined space is strictly advised against due to volatile organic compounds (VOCs).
