Step by step
Use a grout saw or oscillating tool to remove old grout from the joints.
Vacuum out dust and debris from the joints.
Mix new grout to a peanut-butter consistency and apply with a rubber float, packing joints diagonally.
Wipe excess grout off tile faces with a damp sponge before it fully sets.
Once cured, apply grout sealer (for cement-based grout) to resist future staining.
