Spot repairing grout is not only possible, it's also a great way to fix cracked or crumbling grout lines. Simple remove the damaged grout, wipe down the area, prepare the new grout, then apply.
Yes new grout can be installed on old grout. Make sure the old grout is thoroughly cleaned and then wet before installation. I do this all the time. There is absolutely no need to start over and given the quality of the install you have had so far I would say that starting over might introduce more issues.
You take the grout, and put a dollop of it on your grout float. Then you smear it over the area that has the gap in the grout. The float will automatically fill in all the low spots. Make sure to do several passes with the grout float to get it into all the nooks and crannies.
But yes, you can wet it (lightly) and go over it again with more grout, even if it is unsanded. Once you get it filled properly and it's allowed to cure the unsanded will work fine, it's just a LOT more work to fill, let it cure (shrink), fill again, etc. Once filled and cured the stability is the same as sanded grout.
Spot repairing grout is not only possible, it's also a great way to fix cracked or crumbling grout lines.
The one method I've had the best luck with is using a single edged utility blade and skimming over the tile/excess grout toward the grout lines. This will clean/scrape out the excess grout but not score/scratch the tile.
You can remedy this by using caulk to fill in the cracks and restore the look of the grout. First, remove all loose and cracked grout with a grout saw or Dremel tool. Apply the caulk gently to the cracks, smoothing it down with a plastic spoon. You can also wet your fingers and smooth the caulk by hand.
Fixing missing grout is pretty similar to repairing holes. Give the area a good clean, put new grout in the spots where it's missing, and smooth it out with your grout float. Clean off any extra and let it dry completely.
Mix the grout powder (you can buy it at the home improvement store) with water. Use your fingers to apply the grout between all tiles. (You can also use a rubber grout floater). Remove excess grout.
This really works! The grouting around the tiles in our kitchen and bathroom was looking very tried with several black damp spots. The grout pen covered it all in one coat and was very simple and quick to use. We added an extra coat on the very stained sections and now it all looks like fresh grouting.

epoxy grout is a great choice when you are ready to re-grout a tile project. Because epoxy grout is so much stronger than other types of grout (particularly cement grout), you won't even need to remove all of your old grout. You can apply new grout right over the top of the old grout.
A dedicated grout rake or a Stanley blade is best for removing existing grout. Grout rakes can be both mechanical and electric. Any electric grout rake is usually 240V and has variable speeds. The Rubi Grout Remover helps to remove grout surrounding ceramic and porcelain tiles.
Q: Is regrouting worth it? A: Absolutely! Regrouting can give your space a fresh, updated look while also addressing any potential issues with cracked or deteriorating grout that could lead to moisture buildup or mold.
There are a few different materials to fill in gaps in your grout, but we recommend using a premixed grout. Using a premixed grout is the easiest way to fill grout gaps, as mixes come in a wide variety of colors.

The short answer is, “no.” You cannot put new grout over old grout. With regard to filling in holes and cracks on the surfaces in our homes, we might compare grout repair to drywall repair. For holes in drywall, we would simply purchase spackle, and fill the hole in.
