Parging is the act of covering a part of a building, particularly a brick wall, with plaster or mortar. Strong cement is applied to areas of a wall after covering it with a galvanized mesh, followed by the application of a second coat of cement to smooth out the area. Parging an existing wall or making repairs to an area of parging is essential to ensuring protection against weather conditions like rain or snow, since moisture can enter a wall through cracks and threaten its stability. This makes parging an important service in building construction and maintenance.
