The art will almost completely cover the brickwork of the building, on the South Bank, in London, and will be visible to commuters as they arrive at Blackfriars station.
Curator Cedar Lewisohn said: 'All six artists are really different but their work is stunning. It's a bit like having a dinner party – you pick people who will complement each other and set each other off. There will be a real range of techniques being showcased'.
Exhibitors include abstract psychedelic artist Sixeart, from Barcelona, the New York collective Faile, who are renowned for their use of stencils, and Italian artist Blu, who creates drawings on a grand scale.
Other street artists involved in the project include JR from France, renowned for putting photographs of people from deprived areas of Paris onto walls in the city's affluent districts. Brazilian twin brothers Otavio and Gustavo Pandolfo will also submit ideas for the wall art.
A Tate spokesman said a protective coating would be placed on the wall to avoid damage when they are removed.
The murals are expected to measure 15 metres by 12 metres, and will decorate the Turbine High Wall of the building, which its self is 35 metres tall.
All six have had work shown at museums across the globe but started painting on the street. The show runs from May 23rd to August 25th.
