With resin-based repair mortars the reinforcement bars should be gritblasted and the system applied within four hours. Otherwise a non zinc-rich holding primer may be considered. Rust converters should be treated with caution since some containing phosphoric acid can inhibit cure of the subsequently applied resin. The top coat of any compatible primer or bond coat applied to the substrate concrete or steel bars should still be tacky when the repair mortar is applied.
