[1][9] In 1925, Gallart moved to Gràcia FC and UE Sants, from where he arrived at RCD Español, then under the command of Jack Greenwell,[1][4][9] who, knowing that he was ending his contract, anticipated the intentions of CE Europa, which was close to acquiring his services.

[6][7] Gallart then went to Lugo to join SG Lucense as a player-coach, a role that he replicated at UD Orensana before making a foray into Portuguese football at Flaviense de Chaves, where he retired in 1950.

[1][4][5][9] On 26 September 1926, Gallart made his debut with the Catalan national team against Sabadell FC at Creu Alta in a tribute match to Francisco Cabedo, scoring once in a 4–3 win.

On 10 July 1927, he played against his future club Espanyol in a tribute match to Casimiro Mallorquí and José Maria Canals that ended in a 1–4 loss.

[1][14] On 14 February 1934, he played for an unofficial Spanish team in a friendly against Catalonia, helping his side to a 2–0, with goals from his Oviedo teammates Casuco and Lángara.

[20] During the Civil War, General Franco saw the opportunity to use football as a positive propaganda tool, so he arranged for a match to be played in his home region of Galicia against Portugal, whose leader Salazar was supportive of Francoist Spain.
