Yes, your tiles can be regrouted, and it generally needs to be determined on a case-by-case basis. It may be that your tiles are looking tired, worn, and dirty, and a common reaction may be to consider replacing your tiles with new ones.
However, doing so ends up being not only an expensive project but also a time-consuming task.Through this post, George Ceramic will be showing how re-grouting is done; be it full regrouting, partial regrout, and regrout maintenance.
What causes tile grout?
The main reason for tile grouting is because there is tile cavitation. Tile grouting is a common problem that is caused by two main reasons. The first reason is that the cement used in laying the tiles was not poured, causing the tiles to become hollow.
The second reason is that the tiles have been laid for a long time and the cement has become hollow. When encountering the phenomenon of hollowing out of the tiles due to these two reasons, cement grouting can be used to repair the phenomenon. This method will reduce the damage to the tiles.

What are the benefits of regrouting?
As we noted above, regrouting offers several benefits over re-tiling and is often recommended when tiles are in good condition but grout is starting to deteriorate. One of the main benefits is that it can significantly improve the overall appearance of any tiled area.
With regrouting, you can restore a fresh, clean look at an affordable price that fits every budget. Regrouting is suitable for all tile areas, making it a versatile solution.Additionally, regrouting is a cost-effective option that takes less time than re-tiling.
In addition, it is an environmentally friendly option as it helps to reduce carbon emissions by avoiding mass re-waste.Overall, regrouting provides a cost-effective, time-saving, and environmentally friendly way to enhance the appearance and longevity of tile surfaces.
Getting started with the right tools
The key to making regrouting as efficient and painless as possible is to gather the right tools for the job and properly prep the space beforehand. Trying to chip away at the grout using a chisel or a utility knife will only end in damaged tiles or injury.
The two main tools you should buy for regrouting tile are an oscillating multitool with a grout-removal blade and a carbide-tipped grout-removal tool.Once you’ve gathered your tools, ensure to prepare the area to prevent damage to the surrounding surfaces.
If the grout you’re removing sits above a delicate surface, such as a countertop or bathtub, protect the surface with tape and thick cardboard to prevent the grout from scratching it as it falls.

A step-by-step guide to Regrouting
Fit the oscillating multitool with the grout removal blade and begin cutting the grout out of the joints, being careful not to scar the edges of the tile with the blade. To aid in holding the tool steady, rest your arm against the tile surface as you hold the tool and smoothly move it through the joint.
Refrain from forcing the blade into the grout. Instead, let the blade’s oscillation and vibration do the work. Focus on the grout in the middle of the joints rather than the portion sticking to the tile.If you feel the blade is beginning to work slower, change its positioning on the head of the tool to utilize a sharper portion of the blade.
1. Vacuum Grout Lines
As you cut away the grout with the oscillating multitool, use your wet/dry vacuum to remove any pieces and dust.
2. Manually Remove Remaining Grout
Remove the remainder of the grout using the carbide-tipped manual grout removal tool. To do so, flip the triangular blade until you find a size that fits in the grout line and scrape back and forth to clean away all of the remaining grout.Grout removal tools are designed to scrape away grout without scratching the tiles. However, they can still scratch tiles and should be used carefully.
3. Vacuum Every Grout Line
Thoroughly vacuum the entirety of the tiled surface removing every bit of loose grout and dust from each joint. Failure to do so will compromise the hold of the new grout.
4. Mix New Grout
Mix the new grout according to the manufacturer’s instructions, or simply purchase ready-to-use grout. For most grouts, the instructions will specify mixing a portion of the water in a bucket with a portion of powder, then adding more as you mix to achieve the final mixture and proper consistency.
Properly mixed grout should be thick yet still pourable. If mixed too thin, the grout will run from the grout lines before it sets.
5. Apply New Grout
Using a rubber grout float, scoop the grout from the bucket and smear it into the grout lines. To do so, hold the float at a 45- to 60-degree angle from the tiles and approach the joints at an angle between parallel and perpendicular. This will allow the grout to fill the joint without the float pulling it from the joint. To ensure each joint is filled, make another pass in the opposite direction.
6. Let the Grout Set
Let the grout set for the specified time on the manufacturer’s instructions.Sponge Grout Joints: Soak a grouting sponge and ring out nearly all of the water. Wipe the grout joints and tile surface in a circular motion, smoothing the grout joints and removing the excess grout. Let the grout dry completely.
7. Buff the Tiles
Remove any grout haze left behind on the tiles by buffing them with a microfiber cloth. If necessary, use a haze-removal solution to remove stubborn haze.
8. Seal the Grout (Optional)
Consult the manufacturer’s instructions to determine whether or not the grout should be sealed. If sealing is required, apply the grout sealer to the fully dried grout as directed.
How to Maintain and Clean Grout
Believe it or not, keeping grout clean long-term is possible—even white grout. The key is to ensure the grout is sealed after installation, should the grout require sealing. After sealing the grout, regularly wipe it down with your everyday cleaning to prevent the buildup of dirt and grime.
Always check to make sure whatever product you’re using is safe for tile and grout surfaces, then test it on an inconspicuous spot first. To clean grout that has lost its luster, you can make a strong grout cleaner with items you likely already have on hand.

Is it better to Regrout or retile?
Whether to regrout or retile depends on several factors, and the best choice will vary based on the specific situation. Here are some considerations to help you decide.
1. Condition of the Tiles
Regrout: If the tiles are in good condition without any cracks, chips, or other damage, and you’re only concerned about the appearance or condition of the grout, then regrouting might be the best option.
Retile: If many tiles are damaged, loose, or outdated, it might be a better idea to retile.
Regrout: Regrouting is generally less expensive than retiling since you’re only replacing the grout and not the tiles themselves.
Re-tile: If you want to re-tile, whether it’s interior wall tiles or floor tiles, it involves purchasing new tiles and possibly new grout, which can be more expensive. Additionally, the labor required to remove old tiles and install new tiles can add to the cost.
3. Aesthetic Preferences
Regrout: If you’re happy with the current look of your tiles and just want to freshen up the appearance, regrouting can achieve this.
Retile: If you want to change the look of the space entirely or update to a more modern tile design, then retiling is the way to go.
4. Time and Effort
Regrout: Regrouting can be less time-consuming than retiling, especially if the area to be addressed is small.
Retile: Retiling can be a more involved process, especially if you need to remove old tiles first.
5. Longevity and Future Maintenance
Regrout: While regrouting can give a fresh look, if there are underlying issues like water damage or mold, they might resurface later.
Retile: Retiling, especially with modern materials and techniques, can offer a longer-lasting solution and might be more resistant to future problems.
6. Potential for Damage
Regrout: There’s a lower risk of damaging tiles when you’re only working on the grout.
Retile: There’s a risk of damaging the underlying wall or floor when removing old tiles, which might lead to additional repairs.
In conclusion, if the primary concern is the condition or appearance of the grout and the tiles are in good shape, regrouting is a cost-effective and quicker solution. However, if there are multiple damaged tiles, or you want a completely new look, retiling might be the better option. Always consider consulting with a professional before making a decision.
Can I put new grout over old grout?
Yes, you can put new grout over old grout, but there are important considerations and steps to follow:
1. Depth: For the new grout to adhere properly, there needs to be enough depth to hold it. This usually means removing at least 1/8 to 3/16 inch of the old grout to provide a good base for the new grout to bond to.
2. Clean Surface: The old grout surface must be thoroughly cleaned to remove any dirt, mold, mildew, or soap scum. Any contaminants can prevent the new grout from adhering properly.
3. Type of Grout: It’s essential to use the same type of grout as the original. For instance, if the old grout is unsanded, use unsanded grout for the new layer. Mixing types can lead to uneven coloring and bonding issues.
4. Adhesion: Some professionals recommend using a grout adhesive or primer on the old grout to ensure the new grout adheres properly.
5. Curing Time: After applying the new grout, allow it to cure for the recommended time before exposing it to moisture. This ensures it sets and bonds properly.
6. Sealing: Once the new grout has cured, it’s a good idea to seal it to protect against moisture and staining, especially in areas like showers or backsplashes.
Drawbacks and Concerns
1. Uneven Appearance: Overlaying new grout on old grout can sometimes result in an uneven appearance or color discrepancies.
2. Potential for Failure: If the new grout doesn’t bond properly to the old grout, it can lead to premature failure, cracking, or separation.
3. Underlying Issues: Simply overlaying new grout won’t address any underlying issues, like water damage or mold growth behind the tiles.
While it’s possible to put new grout over old grout, it’s crucial to prepare the surface correctly and be aware of potential drawbacks. In some cases, it might be more effective and long-lasting to remove the old grout entirely and regrout from scratch.
