FAQs

Can I use this primer on plastic parts?

This primer is intended for metal surfaces; ensure you use an appropriate plastic adhesion promoter if applying to plastic substrates.

What is the pot life of the mixture?

Due to the extra fast hardener, the pot life is limited. Refer to the technical datasheet for the exact duration based on your current workshop temperature.

Is this a filler primer or a sealer?

It is a high-build filler primer, which is designed to level surfaces before the basecoat application.

Can I apply topcoat directly over this?

Yes, once sanded smooth and cleaned, you can apply your topcoat directly to the primer.

Does the kit come with everything needed for mixing?

The kit includes the primer and the hardener; however, you will need to provide your own mixing cups and spray equipment.

What should I use to clean my spray gun?

Use a standard lacquer thinner or a dedicated gun wash solvent immediately after finishing your application.

Troubleshooting

Primer is not curing properly

Verify the mixing ratio is accurate and ensure the ambient temperature is not too low.

Surface is clogging sandpaper too quickly

Allow for longer flash-off or cure time to ensure the primer is fully hardened.

Poor adhesion to the substrate

Ensure the surface was sanded to the correct grit and thoroughly degreased prior to application.

Pros and Cons

Pros

  • Excellent filling capability for surface leveling
  • Very easy to sand once cured
  • Includes fast-acting hardener for improved throughput
  • Provides a high-quality foundation for professional finishes

Cons

  • Requires professional-grade spray equipment
  • Involves handling chemical hardeners requiring PPE
  • Limited pot life due to the fast-acting nature of the hardener

Setup, Compatibility & Care

To ensure success, begin by thoroughly cleaning and degreasing the substrate. Mix the primer and the provided extra fast hardener strictly according to the recommended ratio to ensure proper polymerization. Always wear appropriate respiratory protection, nitrile gloves, and eye protection, as this is a chemical-based 2K system. Clean your spray equipment immediately after use with a high-quality thinner to prevent the primer from curing inside the nozzle. Store the components in a cool, dry place and ensure the lids are tightly sealed to prevent moisture contamination.
