Grout color for floor tiles light, or total nonsense?

Hello,

we have chosen floor tiles. In the store, they were also nicely laid out on a board with grout, visually appealing. The grout there was light/beige. (I am not interested in wall tiles here)

The tiler has two standard colors in his range and also offers various color palettes of other grout colors, which naturally cost extra.

The boss of the small tiling company, as well as the tile salesman, advised us against choosing light grout colors, as these would darken significantly after 1-2 years due to dirt/walking around/mopping (through mopping, the dirt is pressed into the grout, since it is recessed, "wiped in"). You can get it clean again, but you would have to scrub it heavily, which would be very time-consuming.

The employee of the tiler who will ultimately lay the tiles, as well as a tile salesman from another building materials store, however, said that the darkening after 1-2 years would not be so dramatic and not as strong as described. Besides, the "wiping in" with narrow joints of 3mm is not so severe.

Visually, we would of course prefer the light grout. This would cause additional costs of about €400 for us. But that would be money thrown away if you really lose the color after 1-2 years.

Therefore, I now hope for real experiences from you. Do you have light grout and have had it for several years? How does it look for you?

Thank you.

I had silbergrau? as grout in the living room in the old house. Tiled and grouted myself.... anyway: at some point I was on my knees brushing Oxi and some stuff with a toothbrush to make the grout in the room look almost as bright as the edges of the room again. Didn't work. Save yourself bright, take dark! I can't imagine that narrow grout reacts differently.

Hello "Kaspatoo".
Here again, the truth lies exactly in between!
If we consider a cement-bound standard grouting for floor tiles, as a client you will naturally notice some soiling after a few months/few years. At first glance, this seems unavoidable. This is quite disturbing for both narrow and wider joints than 3mm.
However, there are also special joint materials, the properties of which have surprised me at construction trade fairs.
One example to mention would be PCI "Nanofug". Even red wine does not stain at all upon contact.
It is similar with mechanical soiling, which can be removed much more easily than usual – making the "crawling on four legs" with a toothbrush in hand unnecessary....

hm whether the products used by the tiler have any nanotechnologies... He has his color palette from a specific supplier for grout colors and that's that. But you don't have any experience with it in the real world (at the fair he himself used brought materials), do you?

Yes, that's exactly how I wrote it! I will never do one thing: advertise a product group if I do not know their properties. That would be unprofessional and would also only show half-knowledge. Regards: KlaRa

Ok, can you then name one or more specific product names for me? Maybe my tiler knows one or the other, yes. But they don't give a warranty, do they?
