One of the most common mistakes when painting metal parts is applying paint directly over rust or without proper surface preparation. This leads to poor adhesion, peeling, and a very short service life of the coating.
If you want a professional, durable finish—and avoid unnecessary spending on primers—this process is essential.
1. Initial Cleaning: Remove Dirt, Grime, and Old Paint
Before attacking the rust, it is critical to remove all surface contaminants, such as:
- Mud
- Grease
- Built-up dirt
- Old or loose paint
This can be easily done using:
- Water
- Soap or detergent
- An abrasive pad or wire brush
👉 This step allows the deoxidizing product to act directly on the metal, not on dirt or residues.
2. Rust Removal With N-001 Deoxidizer–Phosphatizer
Once the surface is clean, apply N-001 Deoxidizer–Phosphatizer, which:
- Removes rust in just a few minutes
- Lightly degreases the surface
- Creates a phosphate conversion layer that improves paint adhesion
Application methods:
- Brush
- Sprayer
⚠️ Important:
This product is acidic. Safety glasses are mandatory, as contact with the eyes may cause serious injury. Gloves and proper ventilation are also recommended.
3. Rinsing and Final Cleaning
After the product has reacted and the rust has been fully removed:
- Rinse thoroughly with clean water
- If available, you may use water mixed with SERVEC 1 to further improve surface preparation
- This step is optional, but recommended for high-demand applications
The goal is to eliminate any chemical residue before drying.
4. Complete Drying
Before painting, the part must be completely dry.
Trapped moisture is one of the main causes of premature coating failure.
Drying can be done:
- At ambient conditions
- With compressed air
- With controlled heat, depending on the process
5. Paint Application (No Primer Required)
Thanks to the phosphate layer created during the process:
- Paint adhesion is significantly improved
- Corrosion protection is increased
- Overall finish quality is enhanced
- The service life of the part is extended
💡 Best of all:
This process allows you to paint without using primers, resulting in:
- Fewer products
- Fewer process steps
- Lower costs
- Higher efficiency
Conclusion
Properly working with oxidized metal parts before painting is not complicated, but it does require a structured process.
Good cleaning, correct use of a deoxidizer–phosphatizer, and proper drying make the difference between a coating that lasts months and one that lasts years.
Investing a few extra minutes in proper metal preparation is the key to achieving professional, durable, and cost-effective results.
