Born in Alvor (Portimão), Algarve, Lourenço started playing for local G.D. Torralta, going on to spend five seasons with the team in his first spell, two in the third division. In 1981–82, in the second of his two stints with Algarve neighbours Portimonense SC, he appeared in two games in the Primeira Liga, with his team finishing in sixth position; he was also part of the roster in the following year.
Lourenço's last spell with the professionals was in the 1984–85 campaign with first club Torralta, in second level. Subsequently, he moved to the lower leagues (including the regional divisions), representing mainly A.C.R. Alvorense 1º Dezembro – previously known as Grupo Desportivo Recreativo Alvorense – and playing until well past his 50s.
