Product Information
Full details
The Octoral HS Primer Surfacer (PF131B-3) is designed for professional automotive refinishers seeking a versatile, high-build solution for body preparation. Its primary benefit lies in its dual functionality as both a high-filling surfacer and a non-sanding surfacer, significantly improving workflow efficiency; however, users must be prepared to manage the specific mixing ratios required for the included fast hardener to avoid premature curing.

FAQs
Can I use this on plastic parts?
This is a 2K polyurethane primer generally designed for metal substrates. Always check for a plastic adhesion promoter if using on raw plastic components.
What is the primary benefit of the black color?
The black color helps in achieving better coverage for dark basecoats and serves as a built-in guide coat to highlight imperfections during the sanding process.
Does this product require a hardener?
Yes, this is a 2K (two-component) product that requires the included fast hardener to cure properly.
Can I use this as a non-sanding surfacer?
Yes, the product is specifically formulated to be used as a non-sanding (WOW) surfacer for professional applications.
How long does it take to cure?
Cure times vary based on ambient temperature and humidity. Always consult the technical data sheet for the specific cure schedule of the fast hardener provided.
Is this product suitable for spot repairs?
Yes, its high-filling properties make it excellent for spot repairs on body panels, though the 4000ml size is best suited for regular, high-volume use.
Troubleshooting
Primer is hardening too quickly in the spray gun.
The fast hardener is sensitive to high temperatures. Work in a cooler environment or mix smaller batches to account for the pot life.
Poor sanding performance or clogging of sandpaper.
Ensure the primer has fully cured for the recommended time before sanding. If it clogs, the curing process may have been incomplete due to incorrect mixing ratios.
Surface appears uneven after non-sanding application.
Check your spray gun settings and overlap technique. Ensure the substrate is clean and free of contaminants before application.

Setup, Compatibility & Care
For optimal results, ensure the surface is thoroughly cleaned and degreased before application. Mix the primer with the included fast hardener according to the manufacturer's technical data sheet specifications to ensure proper chemical cross-linking. As a 2K polyurethane system, it should be applied in a well-ventilated area using appropriate respiratory protection. After use, ensure the container lid is sealed tightly to prevent moisture contamination and store the product in a cool, dry environment away from direct sunlight.
