Product Information

Full details

The Roberlo Multyfiller Express is designed for professional automotive body shops and technicians who require a high-efficiency primer filler that accelerates throughput. Its primary advantage is an exceptionally fast drying time, which minimizes downtime between application and sanding; however, users must adhere strictly to the 4:1 mixing ratio and ambient temperature requirements to ensure optimal curing and adhesion.

Extended Product Information

FAQs

What is the mixing ratio for this product?

The product must be mixed at a 4:1 ratio, using 4 parts of the Multyfiller Express to 1 part of the P6000 hardener.

Can I use this for wet sanding?

Yes, this primer filler is fully compatible with both wet and dry sanding techniques.

How long does the product last once mixed?

Due to the fast-acting nature of the P6000 hardener, you should only mix the amount you intend to use immediately, as the pot life is limited.

Does this kit include everything needed?

The kit includes the 4L primer and 1L hardener; however, you will need your own spray equipment, mixing cups, and thinner if required by your specific viscosity preference.

Is this suitable for DIY projects?

While effective, this is a professional-grade product that requires proper spray equipment, safety gear, and knowledge of automotive painting processes.

Troubleshooting

Primer is not drying as expected

Verify that the ambient temperature is within the recommended range and re-check the mixing ratio of hardener to primer.

Surface appears rough after spraying

Check your spray gun settings, fluid tip size, and air pressure to ensure correct atomization of the product.

Poor adhesion to the substrate

Ensure the surface was properly cleaned, degreased, and sanded according to the repair specification before primer application.

Pros and Cons

Pros

  • Significantly reduces cycle time due to fast drying
  • Suitable for both wet and dry sanding
  • Consistent, high-build finish quality
  • Professional-grade adhesion and durability

Cons

  • Requires precise 4:1 mixing ratio
  • Limited pot life due to fast-acting hardener
  • Professional equipment required for proper application

Setup, Compatibility & Care

To ensure proper performance, always mix the 4 liters of primer with the 1 liter of P6000 hardener in a strict 4:1 ratio by volume. Utilize a calibrated measuring cup or mixing stick to avoid off-ratio applications which can cause soft spots or poor adhesion. Application should be performed in a clean, dust-free environment with appropriate spray equipment. After use, clean your spray gun immediately with high-quality solvent to prevent the fast-curing resin from hardening inside the nozzle or internal passages. Store containers in a cool, dry place, ensuring lids are tightly sealed to prevent moisture contamination.
