Traditional stucco siding is a type of building cladding that has been used for centuries. It consists of a mixture of Portland cement, sand, water, and sometimes lime, which is applied to the exterior of a building in several layers. The first layer, called the scratch coat, is applied directly to the building’s structural sheathing and serves as a base for the subsequent layers. The second layer, the brown coat, is applied over the scratch coat and smoothed to provide a more uniform surface. The final layer, the stucco finish coat, is applied to create a decorative surface that can be painted or left natural. Traditional stucco is known for its durability and resistance to weather and fire, making it a popular choice for residential and commercial buildings.
