What is the typical coverage of a 400ml Spray Paint Aerosol?

Although coverage may vary from sprayer to sprayer, the typical coverage is around 2 meters squared per 400ml aerosol spray paint.

As you will require a minimum of 2x applied coats, typical coverage is 1 meter squared per aerosol canister.

Recommended film thickness is 30-40 microns per coat, however this will vary on actual use and specification. Great care should be taken to achieve DFT (Dry Film Thickness) stated in the agreed specification and avoid areas of excessively low or high thickness.
