Use:
Remove dirt, grease, oil, loose rust, and all other surface contaminants using suitable methods.
Lightly sand undamaged coatings. The surface must be clean and dry during application. For optimal results, the relative humidity should be below 85% and the aerosol temperature above 0 °C. Remove the protective cap. After you hear the mixing ball rattle, shake vigorously for at least one minute. Shake frequently during use. Hold the can approximately 25cm from the surface. Move back and forth, keeping the can parallel to the surface. Make sure the can is moving when you press the nozzle to avoid runs. Apply several thin coats at intervals of a few minutes to achieve a sufficient coating thickness. After use, turn the can upside down and press the nozzle for 2 to 3 seconds to clean the valve.

Storage:
Effective for 3 years from the date of manufacture when stored in dry, well-ventilated areas, out of direct sunlight at temperatures between 5 and 35 °C.

Please note:
Practical coverage depends on many factors, such as the roughness of the substrate and material losses during application. Please consult the safety data sheet and safety information provided on the packaging.
