The 1-litre U-POL System 20 S2025 High Build Primer in Grey is a versatile 2-in-1 primer that functions as both a primer filler and a primer surfacer. It is compatible with U-POL's System 20 range of hardeners, specifically S2030 and S2032. Ideally suited to various tasks, from spot repairs to full panel applications, it can be air-dried, low-baked, or infrared-cured.
It has exceptional film build surface levelling properties, making it easy to sand and providing perfect gloss hold-out. Additionally, it is suitable for various substrates, including original paintwork, mild steel, E-coat, SMC, and U-POL Polyester Fillers.
It is recommended that you degrease and abrade the surface before applying any primer and use an HVLP Gravity Gun for best results.
