As of the next football season 2014-2015, vanishing spray will make its appearance on Belgian football fields. The Pro League announced this on Friday. Expo-Line football will launch its own version of the dissolving referee foam.

Vanishing spray helps referees when taking free kicks. Footballers do everything to win space. As a referee, you cannot turn your back without the ball being put forward or without moving up the wall.

Vanishing spray puts an end to this. A solid, white line clearly marks where the ball and wall should be at the moment of the free kick. Once the free kick is taken, this line dissolves by itself. 

Vanishing spray is used for fouls in areas of real danger to goal. The referee decides when to use it.

Vanishing spray is used via a spray can that is firmly anchored in a spray can holder.
