A method of coating a product ( 1 ), carried on a surface of a delivery mechanism ( 3 ), with a coating substance ( 8 ). The method comprises delivering the coating substance ( 8 ) to a location ( 15 ) above said surface carrying said product ( 1 ), and allowing the coating substance ( 8 ) to fall under gravity in the direction of said surface. During its fall, the coating substance ( 8 ) is subjected to at least one pressurised gas stream, and at least one electric field, whereby the failing coating substance ( 8 ) is both dispersed and charged.
