The grout is not anthracite but partially gray?

Hello everyone,

we need your advice and support regarding the grout in the ground floor of our house.

In our ground floor, tiles from the company Caesar, Easy Root Nacciola were installed.

The grout was done with a flexible joint in anthracite. Overall, the floor looks really great.

However, in a few places the flexible joints are not anthracite but rather turn into a light gray. The tiler told us back then that it was cement haze (or dirt or dust from the house construction) and that it would go away again over time. We should clean the tiles thoroughly with cement haze remover anyway, then it would work.

Unfortunately, in some places it is still gray.

Therefore, I wanted to ask you if you have had similar experiences and how you got the haze out of the joints. Maybe with a special grout cleaner or a steam cleaner?

I had briefly considered using grout color to make everything uniform, but I am afraid that might go wrong or not look good.

I look forward to exchanging ideas with you and also to tips and advice. If needed, I can also send photos.

Best regards,
Micha

A photo would be really helpful. How many spots over how many sqm are brighter?

Hi, I have uploaded two pictures for comparison. The joint or the material of the joint is definitely identical.

Merry Christmas!

You cannot compare anything in the photos. Even the tile appears in a different color.

Sorry, but the joints are clearly different in your color

Would you maybe like to take a photo showing both joint colors? That way, it really could just be due to the lighting...
