Like everything else, the structure of your brick walls eventually deteriorates. The brick mortar between the mortar joints eventually tends to wither away, and atmospheric agents play a major role in this. It’s even possible to find some bricks breaking off when water seeps into the joints. For this reason, you will need to use brick pointing to revitalize the structure of your bricks. This involves using cement mortar or lime mortar to repair or finish the brick mortar joints.
Brick pointing is required for the entire structure because it is difficult to determine which brick points are affected by atmospheric air or water. The procedure is carried out up to 10–20 mm, and it usually results in a good, sturdy structure with an even, aesthetically pleasing appearance. The following are the techniques used by contractors for brick pointing:
Flush pointing
Due to its lack of tolerance for atmospheric damage, this is the most frequently used brick pointing method. The raked joints are hard-pressed into the mortar while a masonry unit completes the flush. After that, the edges are carefully trimmed with a trowel or straight edge. Although this type of brick pointing won’t look the best, it will help keep any damages that will occur later. It makes sure that the dust and water cannot get inside and deteriorate the building.
Struck pointing
Water can run off the wall with this type of brick pointing because it doesn’t seep in too quickly. With the exception that the mortar filling’s have inclined direction, it is similar to flush pointing in most respects. Its face is pushed inward to a height of approximately 10 mm from the upper side, creating an inclined position that facilitates easy water drainage.
Grooved pointing
This is another version of flush pointing modification. Grooved pointers are appropriate for ashlar or masonry projects. They create an elegant appearance when a tool is used to form a semi-circle shape after mortar filler has been applied to the joints. Similar to rubbed pointing, all of these pointing structures form when a suitable tool is used to make the groove at half of the height.
Tuck pointing
This involves cleaning out old mortar from joints and adding new mortar that complements the bricks. The mortar joints are then filled in the center with filets or lines of putty in a contrasting color. The center of the groove is carved out for a thin channel that is 3 mm deep and 5 mm wide. White putty cement is then poured into the hollow. It is referred to as half tuckpointing or bastard pointing if the projections are made in the form of mortar.
Beaded pointing
You can use steel or an iron with a concave edge to create this beaded groove. Although it will look flawless, this kind of brick pointing is more prone to break. Your bricks will begin to crumble due to atmospheric damage and the gaps are created by the grooves allowing water to seep in.
Although brick pointing is difficult, brick pointing contractors can complete the task correctly for you. Ensure that you employ one from RZ Constructions.
