To help retain marble’s durability and beauty, you can follow these tips:
To get rid of the sand or grit, sweep the floors daily. If you walk over the sand particles, it can cause scratches on the marble floor.
Keep acidic liquids off the marble floor since they can stain the marble. Make sure the cleaning product you use for marble floors has a label saying the product is suitable for marble floors.
Sealing the floor is very important. If you have a honed finish, seal it twice per year. If you have polished marble, seal it once a year.
