Product Information
Full details
The U-Pol Reface 2K Polyester Spray Filler is designed for professional automotive technicians and body shop specialists who need to quickly level out surface imperfections on large repair areas. Its primary benefit is the high-build formula that significantly reduces manual sanding time by filling pinholes and minor irregularities in one application; however, users should note that as a 2K product, it requires precise mixing with the included hardener and has a limited pot life after activation.

FAQs
Can I apply U-Pol Reface over aluminum?
While it adheres to many substrates, it is primarily optimized for steel and glass fibre. Always check the current technical datasheet for specific substrate compatibility updates.
How long does this product last once mixed?
Due to the 2K chemistry, the pot life is usually limited to 20-30 minutes depending on the temperature. Mix only what you can spray immediately.
Is this a final primer or a filler?
It is a spray filler intended to fill imperfections. You should typically follow this with a finer primer-surfacer or sealer before the final basecoat/clearcoat.
What grit should I use to sand the filler?
Start with P180 for initial leveling and progress to P320 or P400 for a smooth finish before priming.
Does this product require a specific type of spray gun?
Yes, it requires an HVLP gun with a larger fluid tip (1.8mm to 2.2mm) due to its high solids content.
Is this product safe for interior use?
No. Like all automotive 2K spray products, it should only be used in a professional spray booth with proper ventilation and respiratory protection.
Troubleshooting
Material is not curing properly
Check the hardener ratio and ensure the ambient workshop temperature is above 15 degrees Celsius.
Spray gun is clogging during application
Ensure the nozzle size is sufficient (1.8mm+) and that the material was strained properly before pouring into the pot.
Surface cracking or 'crows feet' after sanding
This is often caused by applying coats too heavily without enough flash-off time. Allow more time between applications.
Pros and Cons
Pros
- High-build capability reduces the need for multiple coats
- Excellent adhesion to steel and fiberglass substrates
- Minimal shrinkage post-curing
- Creates a smooth, level foundation for professional-grade paint finishes
Cons
- Short pot life requires fast application after mixing
- Requires proper spray equipment (HVLP gun)
- Professional-grade PPE is mandatory due to chemical vapors
- Requires specific temperature conditions for optimal curing
Setup, Compatibility & Care
- Surface Prep: Ensure the surface is thoroughly degreased and scuffed with P80-P180 grit abrasive before application.
- Mixing: Add the specified ratio of hardener to the Reface filler. Use a calibrated mixing cup to ensure accuracy, as incorrect ratios will lead to curing failures.
- Application: Apply in medium-wet coats. Allow sufficient flash-off time between coats as specified on the product technical data sheet.
- Compatibility: Compatible with most modern automotive topcoat systems. Ensure the filler is fully sanded and cleaned before applying primer-sealer.
- Equipment Care: Because this is a 2K product, clean your spray gun immediately after use with an appropriate solvent. Do not leave mixed material in the gun, as it will harden and permanently damage the equipment.
