Kota Stone is a fine-grained variety of limestone, quarried at Kota district, Rajasthan, India. Hundreds of mines are located in or near the town of Ramganj Mandi and in the Kota district.
The greenish-blue and brown colours of this stone contribute to its popularity. Other colors are black, pink, grey, and beige. When used for building, the stone is mainly used for exteriors, but will also work when used for interiors.
Limitations
Kota Stone flakes; however, periodic polishing using polishing wax can eliminate this phenomenon. Since it is limestone, it is not resistant to acid and alkali. The stone is used throughout India, especially in government offices & institutions.
Advantage
Waterproof; It is not water absorbent and is anti-slip hence is the most perfect and hygienic flooring for humid areas.
