Stucco siding is a siding material made of Portland cement, sand, lime, and water. Applied in three coats over a lath base, it provides a solid, durable, and seamless home exterior. Some advantages of stucco include a natural resistance to fire, lasting durability, and low maintenance.

Most newer homes with exterior stucco have an acrylic-polymer finish, which will expand and contract with the weather. This keeps cracks to a minimum.
