U-POL REFACE is a high-performance, 2K sprayable polyester filler specifically developed to level out large, uneven surfaces and repair heavy sanding marks or deep "map" lines. Often referred to as "liquid gold" by refinishers, it acts as a bridge between body filler and primer, providing a perfectly flat foundation on complex panels or large-scale restoration projects.
Key Performance Features:
- High-Build Filling: Capable of achieving massive film thickness (up to 200–300 microns) in just a few passes, easily filling pinholes, deep scratches, and surface irregularities.
- Rapid Drying: Despite its high build, REFACE dries quickly and can be ready to sand in as little as 2–3 hours at room temperature.
- Easy Sanding: Formulated to sand effortlessly to a fine, dry powder, allowing you to achieve a perfectly level surface without the effort required by standard body fillers.
- Shrink-Resistant: The 2K polyester technology ensures that once the product is cured and sanded, it remains stable without "sinking" into repairs later.
- Versatile Adhesion: Bonds aggressively to bare steel, aluminum, galvanized surfaces, GRP/Fiberglass, and original cured paintwork.
Professional Application Guidelines
Because this is a polyester-based sprayable product, specific equipment and techniques are required:
- Gun Setup: Use a dedicated "filler gun" with a large nozzle (typically 2.0mm to 2.5mm) to handle the high viscosity.
- Mixing: Mix the white base with the included liquid hardener thoroughly.
- Caution: Do not over-catalyze, as this can lead to "bleeding" through the final topcoat.
- Application: Apply 2 to 3 even coats. Allow a 5–10 minute flash-off between coats.
- Sanding: Start shaping with P120 – P180 grit and finish with P240 – P320 before applying a 2K primer.
- Important Isolation: REFACE is a polyester filler and must be overcoated with a 2K Primer (like S2025) before applying any basecoat or topcoat to ensure a proper seal.
Expert Tip: REFACE is a "game-changer" for restoring classic car panels that have ripples or multiple repair areas. Instead of skimming the entire panel with hand-applied filler, spraying REFACE allows you to block-sand the entire surface as one unit, ensuring perfectly straight body lines.
Safety Warning: This product requires a liquid peroxide hardener. Avoid skin contact and wear a properly fitted respirator. Clean your spray gun immediately after use with cellulose thinners; if polyester filler cures inside the gun, it is nearly impossible to remove.
