The decision follows a successful trial of the foam-like substance during the FIFA Club World Cup, currently being played in Morocco, reports Xinhua.
"We started using it in all competitions this year and at the World Cup we will definitely keep on the same path," FIFA president Sepp Blatter said Thursday.
"For the discipline of the game, it's good. I was sceptical at first, but after talking to referees who used it, they were all happy with it."
During the trial, referees carried an aerosol can of the water-based substance to mark the minimum 10-metre distance between the wall and free-kick taker.
The 2014 World Cup will also feature goal-line technology for the first time in football's signature tournament.
