This makes the product particularly suitable for a wide range of repair and finishing tasks. ### Excellent filling power and fast drying time With its high filling capacity, this primer creates a smooth and even surface, ideal for further finishing. Moreover, the primer dries quickly, increasing the efficiency of your work. At a temperature of 20°C, the primer is dust-dry after 2-5 minutes, touch-dry after 5-10 minutes, and ready to sand after 45 minutes. ### Easy application The spray can is equipped with an adjustable nozzle, giving you a spray pattern comparable to that of a spray gun. This ensures a professional finish without the need for additional equipment. For optimal results, it is recommended to shake the can well before use and thoroughly clean and degrease the surfaces to be treated. ### Overcoatable After drying, the Spraymax 1K Unifill S4 can be overcoated with both solvent-based and water-based paints. This offers flexibility in the choice of finishing coats and ensures a durable end result. ### Technical specifications - **Color**: Medium grey (S4) - **Content**: 500 ml - **Drying time at 20°C**: - Dust-dry: 2-5 minutes - Touch-dry: 5-10 minutes - Sandable: 45 minutes - **Recommended sandpaper**: - Wet sanding: P500 - P800 - Dry sanding: P400 - P500 ### Application advice For best results, apply 3 to 4 coats, with a dry film thickness up to 150 μm.
