If your grout is cracked or missing in spots, you'll need to do some prep work before you fix the grout between tiles. To repair cracks, use a caulking gun and silicone caulk designed for wet areas. Fill cracks flush with the tile surface or slightly below.
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.
You don't have to remove all of your old grout to apply the new grout. The new grout can be applied right over the top of the existing grout. You will need a grout removal tool, which is a small tool with a sharp blade capable of chipping away the grout.
Whoever installed your floors most likely did not seal the grout because it needs time to harden and cure completely.
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 use grout to patch minor cracks, and you can use sanded caulk as a temporary fix.
It is highly recommended to remove your old and damaged grout before applying new grout. So, you are noticing that your grout seems to be separating, cracking, or crumbling?

For high-traffic areas, like the main bathroom, you should consider sealing it every six months, while low-traffic areas like the guest bathroom can be resealed every two years. If you are using epoxy grout, it might not be necessary to reseal it as it is highly water-resistant.
Epoxy grout doesn't need to be sealed at all.
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).
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.

Do You Regrout or Retile? The average cost of tiling a shower is about $1,800–$5,000. Retiling a shower will be a few hundred dollars more once you factor in $2–$5 per square foot to remove the old tiles. Regrouting shower tiles costs significantly less, with an average price range of $700–$1,500.
Grout pens will only temporarily cover your grout's discoloration. That's probably why they are the cheapest option available. We run into the infamous grout pen issue nearly every other week. The project usually goes awry when the homeowner applies the grout pen to the grout and some bleeds over onto the tile.
For pinholes, you can simply dampen the grout and push new grout into the holes to do a quick patch. This method only works for small pinholes. Larger holes can mean more damage to the surrounding grout area. To fix larger grout holes in the shower, you need to dig out the old grout and replace it with new grout.
If you notice that your grout is beginning to stain and accumulate contaminants, it's time for a tile and grout cleaning service, followed by a deep-penetrating sealant. High-traffic shower grout: Should be sealed every six months to one year. High-traffic floor grout: Should be sealed every six months to one year.
That's why you take care to apply grout in an even layer, making sure there are no air pockets or gaps. If you accidentally apply too much grout on your tile, or if the grout isn't mixed properly and dries unevenly, you might be left with a rough surface that's difficult to clean. If this happens to you, don't despair.
While the tile industry does not require sealing, it is always recommended, especially in wet or high-traffic areas. Penetrating sealers are the most commonly used and offer high water, chemical and stain resistance. They provide protection without changing the appearance of the grout joint.
Unsightly Grout Stains and Discoloration:
One of the most noticeable effects of neglected grout sealing is the gradual accumulation of stains and discoloration. Grout is porous by nature, which means it readily absorbs liquids, dirt, and debris.
It is important not to leave any excess sealer on the tile surface because it won't get absorbed and it can leave a sticky surface that can become a maintenance problem.
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.
