Now let us have a look over the different types of pointings, used in civil construction.
1. Flush pointing:
As the name suggests, here, the mortar is flushed to the wall surface. The edges are neatly scrapped and trimmed. This type of pointing gives good bonding strength.
2. Keyed pointing:
They are also said by name rubbed pointing. As you can see in the fig., a groove is formed in the pointing work, which gives a good look to the building.
3. V-grooved pointing:
As you can see in the fig. below, here the groove provided is in a v-shape.
4. Cut pointing:
The mortar is filled in the joints, and the top of the horizontal is pressed inside.
5. Tuck pointing:
After pressing the mortar, a narrow channel is created at the center having 5mm. width and 3mm. depth, where white cement putty is used as a raw material.
6. Beaded pointing:
They are concave in shape, bulging outside as you can see in the fig. below.
7. Recessed pointing:
Here the mortar is pushed inside and finished vertically to the wall surface by about 5-6mm. depth.
8. Stuck pointing:
The face of the pointing is kept inclined, so that water drains easily.
Note: I have not discussed them in detail as the figures shown are self-explanatory.
All these types of pointing are used according to the type of building block used, different climatic conditions, and also to fit into the chosen aesthetic look.

Have a good day.😄😄
