Razak joins Primeiro as a free agent after he was released by Mamelodi Sundowns earlier this season.
The forward spent last season on loan at Bloemfontein Celtic, but was not retained by Sundowns upon his return.
Razak joined Sundowns from Kenyan side Sofapaka FC in 2015, but failed to cement his place in the star-studded Brazilians outfit.
