What is brick parging?
Brick parging is a technique where a thin layer of mortar is applied to the exterior surface of brick masonry.
Parging is defined as a thin layer of mortar applied to the exteriors of concrete or masonry surfaces. This definition includes various surfaces such as foundation walls, bricks, or stones. When specifically applied to brick, it's commonly referred to as brick parging.
What is Parging Made Of?
The mortar used for parging has a typical composition. This coating is typically composed of Portland cement, sand, and water. This simple mix provides the necessary workability and durability for the application.
Purpose and Benefits of Brick Parging
Applying this thin layer of mortar to brick surfaces serves both functional and aesthetic purposes:
- Enhanced Appearance: It helps to create a durable and visually appealing finish, providing a smooth, uniform look that can cover the texture or imperfections of the underlying brick.
- Surface Protection: Parging adds a protective layer that can shield the brick from weathering elements, such as rain and wind, and minor abrasions.
- Moisture Management: While not waterproof, the parge coat can help to shed water away from the underlying masonry, contributing to better moisture control on exterior walls, particularly foundations.
Brick parging is often used on the exposed portions of foundation walls constructed from brick or concrete block, offering a finished appearance and contributing to the longevity of the structure.
