The spray, developed in Brazil and Argentina, is currently being used at the Club World Cup in Morocco and was used at the FIFA Under-20 and Under-17 World Cups earlier this year.
The FIFA president told reporters on Thursday that the innovation has been very positively received after the recent trials.
"I think it's a very good solution, some say it takes too much time and I was also quite sceptical at the beginning but... all the referees who have used the system were pleased with it," Blatter said.
After the award of a free-kick near the penalty area, the referee paces the regulatory 9.15 metres before spraying a line on the pitch to mark the correct position of the wall. The line then vanishes from the pitch within a minute.
It has been used for a number of years in Argentina and Brazil where it is widely accepted that it has reduced defensive encroachment from free-kicks.
"The representative of Bayern Munich said that here they can take free-kicks with the wall nine metres away, while at home it's only five," Blatter said. "It's a novelty....we will start using it in the World Cup in Brazil next year."
However, FIFA's latest initiative has not been met with universal acclaim with Marcello Lippi, coach of Asian champions Guangzhou Evergrande, complaining that the referee had not been measuring the distance correctly during his team's 3-0 defeat to Bayern.
"The wall was 15 metres from the ball," Lippi said.
