ᐅ Damage to Marble Flooring – Cause Unknown

Hello everyone,

On our marble floor, we have noticed damage like the one shown in the picture at several spots. We use a cleaner specifically designed for marble and do not wear shoes inside the house. What could be causing this damage? We cannot link it to any specific incidents and are quite puzzled. Additionally, I would like to know if such damage can be repaired by ourselves or if a professional company is required.

Thank you in advance for your feedback.

Sorry, but what kind of damage? I can't see anything on the photo. Maybe you could mark it? Or do you mean the white spots? I would have attributed those to the photo itself.

Hello, I’m specifically referring to the white spots. This is how they look up close. This is not a reflection in the photo.

Marble is a natural material—and it is not particularly durable. For this reason, there are many factors to consider:

- Inclusions that only become visible over time
- Sand grains tracked in and ground into the surface
and so on.

In the end, it is simply not granite...

I believe these are chemical reactions. Who knows which inclusions react and why.
Maybe there is a professional in this field around.

I would guess it's efflorescence caused by lime. With older marble that hasn’t always been properly treated, this is quite common. After all, it is a limestone.
