First you need to craft a one of the repair kits. I recommend using JEI to check recipes. Starting from gold tie holding a repair kit in your inventory will grant you debuffs like slowness, fatigue. duct tape can be used for repair on the way without the debuffs.
After opening a repair kit, simply insert the item that needs repairing and press "Repair". The durability of the repair kit will be transferred to the item. This works both with vanilla and modded tools/armor.
