Pointing is a technique of strengthening and the repairs of the stone or the brick masonry mortar joints. In scenarios where the old mortar joints crack and disintegrate, the defective mortar is removed by hand or power tool and it is replaced with fresh mortar preferably with the same composition as the original one.

The purpose of the pointing work is to not only protect the mortar joints from the adverse effect of the atmosphere but also improve the appearance of the wall by proving the thickness, the pattern of the joint, texture and the colors more prominently. When the masonry work is externally exposed, the masonry work joint is considered to be the weakest and extremely vulnerable from where the rainwater and the dampness can enter.

There are different types of pointing and to know about them in details, you can go through the points mentioned below:
Flush Pointing
In these pointings, the mortar is pressed very hard in the raked joints and it is finished off by flushing the edge of the masonry unit. The edges are trimmed neatly with straight edge and trowel. It does not provide a good appearance, but the flush pointing is quite durable as it does not provide for any provision of space where water, dust etc. can enter. It is due to this reason that this method is used extensively.
Recessed Pointing
In this case, the mortar is pressed backwards by 5mm or more from the edges. At the time of placing the mortar, the face of the pointing is kept vertical by using a suitable tool. This helps in providing a very good appearance.
Beaded Pointing
This is formed by steel or iron and has a concave edge. It gives a very good appearance but it tends to get damaged easily in comparison to the other types of pointing.
Struck Pointing
This is a modification of the flush pointing. Here the face of the pointing is kept inclined and the upper edge is pressed inside the face by 10mm which drains off the water quite easily.
Rubbed, keyed or grooved pointing
This is a modification of the flush pointing in which the groove is formed at its mid height by using a pointing tool. This provides a good appearance to the pointing.
Tuck Pointing
Here the mortar is first pressed in the raked joint and it is completed by using the flush with the face. When the pressed mortar is still green, the groove or the narrow channel is cut in the center of the groove which has a 5mm width and a depth of 3mm. This groove is then filled with white cement putty and this is kept projected about 3mm beyond the face of the joint. In case this projection is done in the mortar, it is called bastard pointing or half tuck pointing.
V Pointing
This pointing is formed by forming a V-groove in the finishing face of the flush.
Weathered Pointing
This is made by making a V-shaped projection.
