It is surprisingly easy to get caught up in the moment and apply too much grout, without realizing it until the grout has set. If this happens, it can be fixed up to a week later by repeatedly wetting, scraping, and chiseling the grout in order to file it down and shape it.
You can mix up another little batch, grout over the problem areas, and then, after carefully wiping the grout, you can gently pat the grout. Yes, using a damp sponge, you can softly pound the grout into submission. This gets rid of bubbles and fills in cracks.
You can repair damaged grout by digging out some of the grout and replacing it with silicone. Make certain everything has dried completely before applying more silicone and allow plenty of time afterwards for it to dry before using the shower.
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.
To remediate this type of problem to make the grout to be more consistent in color there are products called "grout colorants" that are epoxy based and match some of the typical grout colors. After properly preparing the existing grout joint you paint it over the joint which could be a bit tedious of a process.
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.
Dirt, mold, and mildew build up over time, and the grout darkens. If the existing tile grout has become dirty or discolored—or if you just want a new look—it is possible to change the color of the grout. Coloring grout freshens up the entire tile layout, all without having to replace the tile.
Generally, you should be okay to mix up some grout and touch up any trouble spots in your new grout. Stuff like pin holes, scratches or low spots can be touched up with fresh grout the next day. The trick is to blend in the new grout with the old so make sure you mix it the same way that you mixed it the day before.
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.
Choosing the correct grout is a basic step in the process of regrouting over existing grout. The most common grout types are cementitious (which is unsanded or sanded) or epoxy (which is also sanded or unsanded).
Spot repairing grout is not only possible, it's also a great way to fix cracked or crumbling grout lines.
Most homeowners spend between $600 and $2,500. If looking at the grout in your shower makes you want to bathe in the dark, it might be time to get it replaced. On average, the cost to regrout a shower is between $600 and $2,500 (or $10 to $25 per square foot).
Excess Grout
Grout protruding from between your tiles is a clear sign of an amateur or rushed installation job. If the grout hasn't fully hardened, you can scrape it out with a wooden, preferably oak, stick. This will remove the grout without scratching the tiles.
Fortunately, the holes in the shower's grout can be repaired. If the grout is in poor condition, you may need to replace it completely, but if the grout is in overall good condition, fixing the holes might be sufficient. One thing is certain: the holes in your shower grout should not be left unattended.

Remember the tip on avoiding bleach, ammonia, and other harsh chemicals to clean grout. It would be best if you also avoided vigorous scrubbing. A rough brush and too much elbow grease will remove the dirt, but it could also remove the grout. Another way to prevent grout damage is to use a squeegee on shower walls.
It offers limited stain resistance. Many people will choose the paint option when the grout is not structurally intact. Painting over crumbling grout will only mask the problem and your grout will continue to worsen, making your DIY paint job a waste of time and money.
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.
If cleaning is not possible after 24 hours, then you should not leave your grout haze uncleaned for more than 10 days, otherwise, it will be even harder to remove. Finally, you need to be sure you have the right cleaner for your tile material. Acidic cleaners, for example, should not be used on stone.
Grout comes in many varieties, and it's generally considered to be safe once it has been applied and dries.
Replacing grout is certainly one way to fix the problem. Instead, use UltraCare Grout Refresh, a water-based color seal, available in 40 standard grout colors. It's made for refreshing the look of old, discolored grout, or completely changing the color of the existing grout.
Improper curing or immediate grouting can result in loose tiles being installed, or even cracked tiles.
Step 4: The Slake and Final Mix
Once you're pleased with the consistency, let the grout mixture sit, or “slake,” for about 10 minutes.
