Maston Metal Filler is a 2-component polyester filler containing aluminum pigments. It is especially suitable for car body repairs but can also be used for a variety of other applications. Ideal for large surfaces, particularly metal substrates exposed to vibration and continuous temperature fluctuations.’ Features • Excellent adhesion to metal • High conductivity • Smooth sanding properties Application • On bare steel and aluminum after surface leveling and degreasing • On galvanized steel after leveling and degreasing • On sanded fiberglass (GFK/GRP), over polyester filler, acrylic, and epoxy primers – provided the surfaces are in good condition • On dry and clean concrete and wood surfaces Optimal working temperature: 15–20 °C (min. 12 °C) The mixed product remains usable for approximately 4–7 minutes. Apply in multiple thin layers however, do not exceed 3 mm per application. Drying time: Approximately 20–30 minutes at 20 °C. Lower temperatures will significantly increase drying time. IR drying time: 5–7 minutes depending on layer thickness. Do not heat above 60 °C. Use IR equipment as recommended by the manufacturer. Wait approximately 5 minutes before starting the IR drying process. Sanding: • Coarse dry sanding: grit P80–P120 • Finishing dry sanding: grit P120–P320 Overcoating: Compatible with most types of fillers and paints.
