Brick Pointing NYC
Brick pointing is the method of applying a small amount of mortar into the face joint between bricks. These bricks can either be newly laid ones or old brickwork. In new brickwork, pointing is done to apply harder mortar to increase weather protection on the exposed faces. In old brickwork, the method is used to repair the mortar joints that have been eroded by exposure to various elements.
For laying new and old brickwork, there are several techniques that need to be followed in order to do the task properly.
On new brickwork, brick pointing should be done at convenient intervals. Breaks at convenient points must be held to allow enough time for cleaning out the surface mortar of the section. The mortar in the joints should be scraped to a depth of about 12 mm from the brick surface. A wall can only be pointed when it has been completed.
In terms of old brickwork, the important brick pointing NYC techniques include chipping out the old mortar and pointing it to a right depth. The standard depth is 12 mm from the brick surface.

Repeat the steps until the mortar is flushed with the face of the bricks.
