Brick Pointing Techniques for New and Old brickworks Melbourne
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 brickworks Melbourne,
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 techniques include
chipping out the old mortar and pointing it to a right depth. The standard
depth is 12 mm from the brick surface. In removing the old mortar, angle
grinders are often used. Take note that the process will cause a lot of dust,
so you better wear face mask and goggles as you do the job.
Once
the wall is ready to be pointed, the brick pointing techniques for the mortar
follows. Make sure that the joints are wetted first before being filled with
the pointing mortar.
Make
a fairly stiff mix of the mortar and put a small amount on a hawk. In cutting
off slithers of mortar, a small pointing trowel can be used. Hold the mortar up
on the edge of the trowel and press it into the joints to be filled. Then,
carefully draw the blade backwards. Repeat the steps until the mortar is
flushed with the face of the bricks.
Do
the brick pointing techniques by filling the vertical cross-joints first,
followed by the horizontal bed-joints. When more than a square meter has been
filled, finish it using the required style.
