Yes, Felsite can be used as a kitchen floor covering as it is a type of volcanic rock that is dense, hard-wearing, and non-porous. Its natural resistance to staining and water damage makes it a suitable choice for kitchen floors. However, since Felsite is a natural stone, it requires regular sealing and maintenance to prevent scratches and damage. Additionally, it may not be the best option for households with small children or elderly individuals as it can be quite slippery when wet.
