The invention relates to a method for gluing one or more strands of glass-resin composite, GRC, characterised in that the method comprises the following steps: a) a step of pre-glueing one or more strands of GRC by dipping the one or more strands of GRC in a first aqueous bath comprising a composition based on: - an epoxy compound; and - a blocked diisocyanate compound; b) a step of depositing, on the one or more strands of GRC by dipping the one or more strands of GRC in a second bath, an aqueous adhesive composition based on: - at least one compound A1, compound A1 comprising at least one aldehyde function; - at least one phenol A21; - at least one unsaturated elastomer latex comprising at least one elastomer chosen from the group consisting of butadiène copolymers, styrene-butadiene copolymers, vinylpyridine-styrene-butadiene terpolymers, natural rubber with the exception of chlorinated natural rubber, and mixtures of these elastomers; the blocked diisocyanate content of the aqueous adhesive composition in the second bath is strictly less than 0.50 wt%.
