What Is Parging in Construction?
Parging is a common term used in the construction industry to describe the process of applying a thin coat of mortar or cement to the exterior walls of a building. This technique is primarily used to improve the visual appearance of the walls, provide protection against water penetration, and enhance the overall durability of the structure.
The parging process involves cleaning the wall surface thoroughly to remove any dirt, debris, or loose material. Once the surface is clean, a mixture of mortar or cement is prepared and applied to the wall using a trowel or a sprayer. The layer of mortar is then smoothed and leveled to create a seamless and uniform finish.
Parging serves several important purposes in construction. Firstly, it acts as a protective barrier against water penetration. By creating a waterproof layer, it helps prevent moisture from seeping into the walls and causing damage such as mold growth or structural deterioration. Additionally, parging can also improve the insulation properties of the walls, reducing energy consumption and enhancing the comfort level inside the building.
