Grout color for floor tiles light, or total nonsense?

We had light Nanofug in a round shower covered with glass mosaic made of the aforementioned stones. The joints remained as appealing as new for about 4 years in a household of 5, then we sold the building. The marble adhesive was also from PCI. Over the years, we used PCI materials several times and were always satisfied with them. Developing a patina on the floor – that happened with the light movement joints in the new house.

In our last rental apartment, we had light grout on the floor in the bathroom. It was the first occupation after renovation. After less than a year, the grout was very uneven. In front of the sink, for example, it was noticeably darker. I would not do it, and our tiler also advised against it.

so

- the supposed miracle product is called "Nanofug" and is from the manufacturer PCI?
- you use PCI often? does that mean you are a tile setter?
- Developing a patina on the floor means I have to expect that a layer of dirt will accumulate?

No, Kaspatoo, we are not tile setters. One of our sons-in-law is, and he also provided us with the materials. When you own an old building for 30 years, jobs come up now and then where you can use products, for example from PCI. If you shop at a building materials store instead of a DIY store—which is not necessarily more expensive but better—everyone will probably find reliable manufacturers over time whose products they like to use. Tiling was women's work for us. Laying slabs was men's work.

Patina on movement joints: The floors in the new building were done by the craftsman; we are slowly getting too old, and the formats became larger. What he used to grout the movement joints, I cannot say. But it is certainly a silicone. The surface becomes dirty and gets a dirt film from the almost oily surface, which I have to scrub out with a small brush, as mopping the floor does not remove it. Joint color light beige. Cleaning agent a commercially available all-purpose cleaner. It was worse with neutral soap. Cleaning system Leifheit with scratchy intermediate strips.

So beige becomes dark for you and you explicitly clean the grout regularly with brushes? Just wiping does not keep the grout clean?

I had black tiles and white grout in my rental apartment. I don't know what material. I wouldn't choose a light grout color. You can simply see every little bit of dirt right away. On top of that, lime can also get stuck in the grout, etc. It would just be too annoying for me. I also think it doesn't matter whether the grout is light or dark anyway. After living in the place for a year, all you notice is that the toothpaste is empty.
