Stucco is a siding finish used for lots of commercial and residential structures. Originally it was made from lime, sand, and water. Portland cement is one of the key elements of concrete and can be seen in structures like high-rise buildings and freeways.
Typically two to three thin layers are applied. A trowel is used for the first layer (scratch coating ) to create the scratches necessary for the second layer (brown coat). Also, stucco can may applied to brick, stone, concrete, and adobe, as well as a wood frame or other sorts of material.
