Purpose of Pointing

The pointing work not only protects the mortar joints from the adverse effect of the atmosphere but also improves the appearance of the wall by proving the pattern of the joint, their thickness, colors, and texture prominently.

Method of Pointing In Construction

Following are the steps to be followed while doing pointing work.

Pointing Work
  1. Old mortar from the joint is ranked out to a depth at least 20mm for better bonding.
  2. Remove all dust from masonry joints by using wire mesh.
  3. Wash the joint surface with clean water and kept it wet for a few hours.

Fill the mortar in these joint in desired shape to cover all joint space.

  • Press the mortar into joints with thin trowel still; it sticks to the old mortar surface.
  • Complete all joint similarly. The water curing must be done for at least three days if a lime mortar used and ten days if cement mortar used

Flush pointing is also done by wiping over the finished pointing with the trowel or piece of rough cloth.

  • It does not make a good appearance.
  • But it is durable as it aborts the chances of accumulation of dust, water etc.
  • It is the most popular types of pointing used in building construction.

2. Weathered Pointing

Weathered Pointing
Weathered Pointing

In Weathered Pointing the mortar pressed into a joint, and while the mortar is still fresh the top of the horizontal joints is neatly pressed back by 3-6 mm with the pointing tool. They look like sloping from the top of the joint to the bottom of the joint.


3. Keyed Pointing

In these Keyed types of pointing the mortar is pressed into joints by trowel and well finished off with the face of the masonry surface. After that, the joint is presses back by small-diameter steel lengthwise (6 mm dia). It will form a curved arc groove into a mortar joint. The vertical joint also finishes similar manner.

Keyed Pointing
Keyed Pointing

In this type mortar is first pressed into joints

  • A semi-circular curve type notch is formed by tool or small steel bar.
  • These types of pointing are providing an excellent appearance to the wall.
  • Keyed pointings are mostly used for superior type work, particularly for vertical joints of walls.

In Beaded Pointing, the mortar pressed into a masonry joint and concave grooves are formed into a joint by using a steel tool having a concave shape. Beaded pointing gives an excellent appearance to the mortar joint but is liable to get damaged quickly.


6. Struck Pointing

Struck Pointing
Struck Pointing

In this pointing, the mortar is first filled and pressed to match the face of brick masonry work, and then the top edge of the joint is pressed inside around 10 mm compared to the bottom corner. It will form slope from top to bottom so that that rain wall will drain off quickly.


7. Recessed Pointing

These types of pointing generally not suitable for buildings in exposed situations because they do not readily shed water.

Recessed Pointing
Recessed Pointing
  • Recessed pointings are by pressing mortar back from edges by 5 mm or more.
  • Pressed pointing face is kept vertical
  • It is advisable to use only bricks with excellent frost resistance should be used with recessed joints.
  • It Gives a good appearance.

8. Tuck Pointing

Tuck Pointing
Tuck Pointing
  • In these types of pointing the mortar joint is filled and pressed to the level surface of masonry.
  • While the mortar is still fresh, grooves are cut in the mortar joint. The slot size of 5mm width and 3mm depth. Ti is then filled with white cement putty, kept projecting beyond the face of the joint by 3 mm. in case if these projections are done in a mortar then it is called bastard pointing or half tuckpointing.
