Stucco is a material made from an aggregate, usually sand, combined with a binder, such as water, lime, or cement. The resulting mixture is poured over a surface, usually brick or concrete, and left to cure. After curing, the stucco is hard and durable. It can be painted or stained to match the surrounding surface. Stucco is applied in three coats that are each allowed to dry before the next coat is applied.

There are many factors to consider when installing stucco siding, such as the climate, type of insulation, and wind exposure. In general, the installation process involves applying a base coat and then a finish coat. It's important to make sure that both coats are applied properly in order to achieve a long-lasting finish. Homeowners can usually do the job themselves, but it's always best to consult with a professional before starting any major home renovation project.
