Hello everyone,

We need your advice and support regarding the grout on the ground floor of our house.

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

The grout used was a flexible grout in anthracite. Overall, the floor looks really great.

However, in some areas, the flexible grout is not anthracite but rather a light gray. The tiler told us back then that this was cement residue (or dirt or dust from the house construction) and that it would fade over time. We were advised to clean the tiles thoroughly with a cement residue remover, which should solve the problem.

Unfortunately, a few spots are still gray.

So I wanted to ask if you have had similar experiences and how you managed to remove the residue from the grout. Maybe with a special grout cleaner or a steam cleaner?

I had also briefly considered using grout colorant to make everything uniform, but I’m afraid it might go wrong or not look good.

I’m looking forward to exchanging ideas with you and to any tips or advice. I can send photos if needed.

Best regards,
Micha

I can tell you that later. The contractor is coming today. I’m not doing it myself but having it done as part of the defect rectification. The material comes directly from the grout manufacturer.
I can report the results this evening.

So, the material comes directly from the grout manufacturer. In my case, it’s Sopro. The product is called Fugenfrisch. Of course, you need to use the color that matches your grout. It looks fantastic, everything is uniform now.

That sounds great already. How did he apply it and clean the tiles afterward? What steps need to be followed?

I ordered anthracite as a test.

Simply apply it onto the joints, then rinse off with water and a sponge after a short waiting time. Afterwards, it can be walked on but should not be cleaned with detergents for 3-5 days. It looked really easy and straightforward.
