The Octoral PF131 + H24 HS Primer Surfacer is designed for professional automotive technicians and body shop specialists who require a reliable foundation for high-quality paint jobs. Its primary benefit is its high-filling capacity combined with excellent sanding properties, which significantly streamlines the refinishing process. Users should note that as a 2K Polyurethane system, it requires precise mixing and professional spray equipment, making it less suitable for casual DIY enthusiasts without proper ventilation and safety gear.

This is a 2K Polyurethane system, meaning it requires the addition of a hardener to cure.
It is recommended to use an etching primer or epoxy primer on bare metal first to ensure maximum corrosion protection and adhesion.
Always refer to the specific Technical Data Sheet (TDS) provided by Octoral for the exact H24 mixing ratio for this batch.
Yes, lower temperatures will significantly slow down the curing process, while higher temperatures may cause it to flash off too quickly.
Yes, this primer is compatible with both dry and wet sanding methods, depending on shop preference.
Unopened containers have a shelf life as indicated by the manufacturer, but once the hardener is mixed into the surfacer, it must be used within its 'pot life'.
Ensure the primer has fully cured for the recommended duration before beginning the sanding process.
Verify that the surface was properly cleaned and abraded (sanded) prior to application.
Adjust the spray gun pressure and verify the reduction ratio; ensure the overlap technique during spraying is consistent.
Before use, ensure the surface is clean, dry, and free of contaminants like grease or silicone. Mix the PF131 component with the H24 hardener according to the manufacturer's specified ratio in a clean mixing cup. Once mixed, the product should be applied in an environment with adequate ventilation using appropriate respiratory protection. After application, cleaning spray equipment immediately with high-quality paint thinner is essential to prevent the 2K material from curing inside the gun nozzle. Store the components in a cool, dry place and ensure the lids are tightly sealed to prevent moisture contamination.
