How to Apply Vallejo Mecha Black Primer 70.642

1. Prepare the Model Surface

Remove dust, grease, mold-release residue, and other contaminants. Allow cleaned components to dry completely.

2. Disassemble Where Practical

For articulated models, separate armor panels and components where practical. Protect tight-fitting joints and moving surfaces from excessive paint buildup.

3. Mix the Primer Thoroughly

Mix the primer before use to ensure consistent color and application.

4. Apply with an Airbrush

Vallejo Mecha Primer is designed primarily for airbrush application. Apply controlled thin coats rather than flooding the surface.

5. Start Around 15–20 PSI

Approximately 15–20 PSI is a useful starting range. Adjust pressure according to your airbrush, nozzle size, and spraying conditions.

6. Thin Only When Necessary

Mecha Primer can be airbrushed directly. If adjustment is required, use compatible Vallejo Airbrush Thinner or Flow Improver.

7. Build Coverage Gradually

Apply several controlled thin layers to achieve an even black foundation while preserving surface details.

8. Avoid Excessive Paint on Joints

Moving joints and tightly fitting components can bind or experience paint rubbing if too much material is applied.

9. Allow Adequate Curing

Allow the primer to dry and cure before extensive handling, masking, assembly, or applying subsequent paint layers.

10. Apply Compatible Hobby Colors

Once the primer is ready, apply Vallejo Mecha Color or other compatible hobby paints.

11. Add Metallic Details

Apply compatible metallic paints to mechanical frames, weapons, and other selected components.

12. Apply Weathering Effects

Use compatible washes, pigments, and weathering products to reproduce dirt, grime, rust, and operational wear.

13. Protect the Finished Model

Use a compatible varnish where appropriate for the desired finish and handling requirements.

14. Clean the Airbrush

Use Vallejo Airbrush Cleaner after spraying.

15. Follow Safe Airbrushing Practices

Work in a properly ventilated area and use suitable respiratory protection when spraying acrylic paint particles.
