On 26 June 2008 Gum signed a five-year deal with fellow second tier club Ponte Preta, who acquired 50% of his federative rights. He was an immediate starter for the club after his arrival, impressing in the following year's Campeonato Paulista.
Gum scored his first goals in the main category of Brazilian football on 18 October 2009, netting a brace in a 2–2 home draw against Internacional. He finished the campaign with 16 appearances and three goals, as his side narrowly avoided relegation.
Gum was also an important unit during the club's 2009 Copa Sudamericana run, scoring a goal against Cerro Porteño which granted the qualification to the finals; he also scored the last goal in a 3–0 home win against LDU Quito in the second leg, as his side finished second (4–5 on aggregate).
Gum was a first-choice during Flu's 2010 Brasileirão winning campaign, partnering with Leandro Euzébio and becoming the best defense of the championship. He was also an undisputed starter in 2012, winning another title.
