What’S Beneath The External Stucco?

Stucco is a durable and versatile exterior home finishing plaster coat found on homes nationwide. It is a cement-type mixture made of Portland cement, lime, sand, and water, and is a thin finish coat that goes on the outermost layer of the wall. Stucco is not the least expensive siding option but is the most aesthetically versatile. Common surfaces for stucco include plywood, oriented strand board (OSB), cement board, and exterior grade gypsum sheathing.

Stucco is a porous material that can be penetrated by water, creating mold problems behind a pristine wall. Synthetic forms of stucco can be more water-resistant and consist of water-resistant paper, wire mesh, and other metal components. Stucco renders are of three basic types: a fat lime and sand mix, sometimes with animal hair as reinforcement, or a hydraulic mix containing either hydraulic lime or fat lime.

Stucco is a building material composed of sand, cement, water, and traditionally, lime. It has its roots as a building and artistic material dating back to ancient times. Stucco or render is a construction material made of aggregates, a binder, and water. When applied wet, it hardens to a very dense solid. To install stucco, follow local building codes and find an unobtrusive location to chip away a small section of stucco and fill back in afterwards.
