Lets start, to know about the methods and types of pointing. Pointing is more important for the structure to give pleasure and better appearance. Learn some more structural design spreadsheets and codes here. Firstly we have to prepare the surface. The preparation of surface can be done in two types.

1. New work – All the joints are raked down to a depth of 20 mm while the mortar is still soft.Then the surface and joints are cleaned and thoroughly wetted.
2. Old work – All loose pointing and superfluous mortar on the surface and in the joints are removed.The joints and surface are cleaned, and then thoroughly wetted.

Methods of pointing:-
After preparing the surface and cleaning and wetting the joints as desired above, mortar is carefully placed in desired shape in these joints. A small trowel is used for placing the mortar in the joint.The mortar is pressed in such a way that to bring perfect contact between the old interior mortar of the joint and new mortar.In case of ashlar and brick, the mortar does not cover face edge. The pointed surface is kept wet for at least a week or till it sets after application.

1. Flushing Pointing  :- Flushing pointing is formed by pressing mortar in raked joints and by finishing off flush with the edge of masonary units.The edges are trimmed with trowel but it does not give good appearance.However, the pointing is more durable since it does not provide any space for the accumulation of dust, water, etc.due this reason Flush Pointing is extensively used.

2Recessed Pointing :- This type of pointing is done by pressing the mortar back from the edge by 5mm or more. The face of the pointing is kept vertical, by a suitable tool. This types of pointing outs very good appearance.

3. Rubbed, Keyed or Grooved pointing :-This pointing is a modification of flush pointing forming groove at its mid height, by a pointing tool.It gives better appearance.

4Beaded Pointing :– It is the special types of pointing formed by a steel or irone with a concave edge.It gives good appearance but it liable to damage easily.

5. struck Pointing :- It is also the modification of flush pointing in which the face of the pointing is kept inclined, with its upper edge pressed inside the face by 10mm.This type of pointing drain water easily.

6. Tuck Pointing :- Tuck pointing are those types of pointing which is formed by first pressing the mortar in the racked joint and finishing flush with the face. While the pressed mortar is groove or narrow channel, having 5mm width and 3mm depth is cut in the centre of the groove. This groove is then tucked or filled by white cement puty and projecting beyond the face of the joint by 3mm.If projection is done in mortar, it is called bastard pointing or half tuck pointing.


7. V-Pointing :- V pointing pointing is formed by forming v-groove in the flush finishing face.
