The simplest solution for bathroom and kitchen
Are you familiar with this problem? The frustration with old grout.
Whether in a rented apartment or your own home.
You're standing in your bathroom or kitchen. The tiles are actually still nice, but the overall impression is just not right anymore.
The reason lies in the details: the joints.
Over the years, they discolor, turning gray, yellowish, or even developing dark mold spores. No matter how much you scrub, refreshing tile grout seems impossible. The dirt is deeply embedded in the pores of the cement grout . Many homeowners and renters are now faced with the question: Do I have to completely re-grout my bathroom or even retile? The fear of a huge construction site, noise, and dirt is significant, and the labor costs, if you do end up hiring one, quickly add up to a four-figure sum.
The usual solutions: Why "removing grout" is usually not a good idea
If you search the internet for ways to renew grout in the bathroom , you will usually come across radical methods that create more problems than they solve.
- The "chemical sledgehammer": Extremely harsh cleaners often make the cement joint porous instead of permanently repairing it.
- The grout pen: A pen only provides surface coverage. When renewing shower grout, the water washes the color away again within a few weeks.
- The nightmare of scraping grout: Mechanically removing tile grout creates an extreme amount of fine dust that spreads throughout the entire apartment. Furthermore, you risk damaging the edges of your tiles while scraping.

The ultimate guide: Everything you need to know about renewing, repairing, and coloring tile grout
Why joint care means preserving the value of your property
Grout lines are more than just spacers between tiles. They are crucial for the hygiene and appearance of a room. Neglecting grout renewal not only risks an unsightly look, but in the worst case, moisture damage behind the tiles. But don't worry: Repairing tile grout is easier than ever thanks to modern technologies like Cala Casa. In this comprehensive guide, we delve into the details and answer all your questions about renewing tile grout , repairing bathroom grout , and color trends like silver-gray grout .
The old rule was: if the grout is unsightly, it has to go. This meant removing the grout . The old mortar was painstakingly removed using milling machines or scrapers. The problem with removing old grout :
- Risk: The tile edges chip extremely easily.
- Dirt: Fine dust settles everywhere.
- Time: A bath takes days.
The modern method is called: renewing tile grout without scraping . This involves altering the chemical composition of the surface. A polymeric color layer bonds permanently to the mineral substrate. If you're planning to renew your cement grout , this is the safest way for DIYers. You avoid the risk of damaging your tiles and often achieve a result that looks better than the original grout .
For a long time, grout was either white (in bathrooms) or cement gray (on floors). But changing grout color is now a key element in interior design. One color in particular has become an absolute favorite: silver gray .
Why is the grout color silver-grey so popular?
If you're looking for silver-grey tile grout , you're right on trend.
- Easy to care for: A silver-grey grout is much more forgiving of light soiling than pure white.
- Modern: Silver-grey tile grout looks softer with white tiles than harsh black, but more modern than classic white. It adds texture without darkening the room.
- Versatile: A silver-grey grout color suits both concrete-look tiles and wood-look tiles or classic white metro tiles.
With the Cala Casa system, you can transform any existing grout line into a silver-grey grout . Whether the old grout was beige, white, or dark grey – our high-coverage formula makes it possible to refresh tile grout in your desired color.
Renewing shower grout without scraping is the ultimate challenge. Showers are constantly exposed to moisture, and many conventional paints fail in this situation. If you want to renew your shower grout , you must ensure that the product is hydrophobic (water-repellent). Cala Casa forms a barrier after curing. Water no longer penetrates the grout but runs off. This means:
- Fewer limescale deposits.
- No breeding ground for mold.
- Easier cleaning.
Therefore, renewing bathroom grout with our system is not just an aesthetic measure ( refreshing grout ), but a functional upgrade for hygiene.
We often receive questions about repairing joints when the mortar is already crumbling. It's important to distinguish between the following:
- Visual defects: Discoloration, stains. -> Solution: Renew tile grout without scraping it out (just paint it).
- Substantial defects: Deep holes, cracks. -> Solution: Repair tile joints (filling + painting).
For a perfect tile grout repair when you have holes, you should first get some grout from the hardware store. Fill the holes. The new grout will never be an exact color match for the old. But that's okay! Once the grout is dry, you can paint over everything with Cala Casa ( re-grout ). This way, you perfectly conceal the repaired areas, and no one will be able to tell that you had to partially repair the tile grout .
Yes, renewing grout on floor tiles works in principle the same way as on walls. However, the stresses are different. While water and soap are the main culprits on walls, on floors it's shoes, vacuum cleaners, and mops. If you're planning to renew old grout without scraping it out on the floor:
- Clean extremely thoroughly beforehand (use a degreaser!).
- Allow the paint to cure for longer (ideally, do not walk on it for 24-48 hours).
- The result is a silver-grey (or other color) tile grout that looks like new and instantly enhances the room.
We preach the importance of renewing tile grout without scraping it out , but there's one exception: silicone sealant . The elastic joints in the corners (maintenance joints) aren't made of cement. If these become moldy or cracked, you actually have to remove the old grout . Painting won't help here. Our tip for a complete renovation ( renewing bathroom grout ):
- Cut out the old silicone ( remove the joints ).
- Renew the cement joints with Cala Casa ( re-grouting tiles without scraping ).
- Finally, apply a new silicone sealant that matches the color of your new grout, silver-grey (or your choice).
Having tiles re-grouting done by a professional is expensive.
- Tradespeople: Travel costs + hourly wage (scraping is time-consuming!) + materials. Easily €500-€1000 for a small bathroom.
- DIY (Cala Casa): Material costs for the set (under €50). Time required: One Saturday morning.
Repairing tile grout yourself saves you a significant amount of money, which you can then invest in attractive accessories. Plus, you avoid waiting for a professional. With these instructions for regrouting tiles, even a complete novice can get started right away.
Whether you want to repair bathroom grout , color tile grout silver-grey , or simply remove tile grout hygienically (for aesthetic reasons): The answer almost always lies in finishing rather than replacement.
