Yes, both marble and granite can be used outdoors depending on the specific type and finish. Granite is generally more suitable due to its durability and resistance to weathering. Proper sealing and maintenance are essential for outdoor use to protect against weathering and staining.

Both marble and granite are natural materials, which means they are extracted from the Earth’s crust. The environmental impact varies depending on factors like extraction methods, transportation distances, and waste management practices. Some companies promote sustainable practices such as recycling water and minimizing waste during processing.

Marble and granite require different care routines. Marble should be sealed regularly to protect against stains, and acidic substances should be avoided to prevent etching. Granite is less prone to staining but should also be sealed periodically. Both should be cleaned with pH-neutral cleaners and soft cloths to avoid scratching.
