How to Regrout Over Existing Grout
Old or damaged grout can make your tiles appear unsightly. If you have an existing tile wall or floor with grout lines that have become cracked and crumbly in places, you don't necessarily have to replace all the grout. If the damaged areas are isolated to a few spots, you can extract and replace just the damaged areas. See your tile supply store for the right grout-removal bit for your type of tile and drill. Does this Spark an idea?

Allow the grout to sit for 10 minutes. Use the damp sponge to wipe up the residual grout from the surface, running the sponge flat over the surface so it will leave the grout in the lines and smooth it out.
