pointing refers to the process of filling mortar in brickwork or masonry joints to improve the weatherproof condition of the structure . It is a finishing technique used to complete the mortar joints in masonry, whether it's stone or brick .
Purpose of Pointing
The primary purpose of pointing is to provide a durable and weather-tight seal to the joints in masonry structures. This helps to prevent water penetration and ensures the structural integrity of the building .
Depth and Filling of Joints
In Australian commercial construction projects, pointing typically involves filling joints to a depth of 10 mm to 20 mm with high-quality mortar in the desired shape .
Repointing
Repointing is the process of repairing or replacing existing pointing mortar in stonework or brickwork. This may involve removing hard cement mortar and replacing it with new mortar .
here are different types of pointing techniques used in Australian commercial construction projects, including:
Flush pointing: This technique involves filling the joints with mortar that is level with the surface of the bricks or stones, creating a smooth and uniform appearance.
Weathered pointing: This technique involves filling the joints with mortar that is slightly recessed from the surface of the bricks or stones, creating a weathered or aged appearance.
Recessed pointing: This technique involves filling the joints with mortar that is deeply recessed from the surface of the bricks or stones, creating a more pronounced and textured appearance.
Raked pointing: This technique involves removing some of the existing mortar from the joints and replacing it with new mortar, creating a raked or grooved appearance.
Beaded pointing: This technique involves applying a bead of mortar to the joints, creating a decorative and textured appearance.
The choice of pointing technique depends on the desired aesthetic and functional requirements of the project. For example, flush pointing may be used for a modern and minimalist appearance, while recessed pointing may be used for a more traditional and rustic appearance.
