Some say you can acid wash the existing grout and grout over it.
This will not work if unless the primary layer of grout is very thinIt still has limted results
Have you thought of staining it?
They sell grout stain.

If the existing grout is cracked, floating new grout over it will most likely crack as well. The only best option, if you want it to last, and look better, is to remove the old grout. They sell grout remove tools at homecenters. Using a Dremel tool with the appropriate attachment will speed things up.

If you can live with the small cracks, and pits, they do sell grout dye like ifllc stated. I recently did this after my grout job went arye. I bought it from

They can match almost any color grout you want.

hi Robby..
I have to agree with Ifllc and HotinOKC, but if you have small grout line joints like 1/4 inch or less you donít have to remove the old grout so deeply with complicates tools, just remove the loose grout and go whit a construction knife o cutter and make a grove with it just enough to let the new grout go in
I would do like that.
