What is parging used for in construction?

Parging is a construction technique that involves applying a thin coat of cement or mortar to the exterior surface of a wall. This process is primarily utilized to create a smooth surface on walls, particularly masonry walls. By doing so, it not only improves the visual appearance of the wall but also provides protection against weathering and other potential damage. Parging can help fill in small cracks and imperfections in the surface, leading to improved durability and a more uniform texture.

While enhancing the aesthetic appeal is an important aspect, parging also serves functional purposes, such as preventing moisture penetration and improving the overall longevity of the masonry. The application process typically involves troweling the material onto the surface to achieve a consistent finish, which makes it a common practice in the finishing stages of construction and renovation.

Options that suggest reinforcing structural integrity, insulating foundations, or enhancing rooftop aesthetics do not accurately represent the primary purpose of parging in construction.
