  1. pointing • Pointing is the process of filling the masonry joints with the mortar of slightly richer mix. • The rain water may enter through the mortar joints. Therefore, the mortar joints in masonry are raked out to a depth of 12mm & then it is filled with rich mortar. • The pointing protects the joints from the entry of rain & also increase the appearance of the surface with the different pattern of the joints, thickness, colors & texture.

  2. Final treatment with cement or lime mortar made to the joints of the masonry to provide neat appearance is termed as pointing. • The joint on the face of stone or brick masonry are roughly filled in while the walls are being raised. • They are after wards neatly finished off to make them water tight. • The joints thus finished, give a better appearance to surface and prevent rain water from entering the

  3. Purpose: • To prevent the moisture and the rain water from entering the interior of masonry through joints and to make them durable. 2.To improve the appearance of the structure.

  4. SUITABILITY • Pointing is preferred to plastering under following conditions. 1. When a smooth and even surface is not essentially required. 2. Where it is desirable to exhibit to view the natural beauty of the materials (bricks or stones) used in construction. 3. When the workmen ship is neat and good.

  5. Types of pointing • FLUSH POINTING • In flush pointing, the mortar is pressed into the raked joints & finished flush with he edges of the bricks or stones. • The edges are then nearly trimmed with a trowel & straight edge. • This is the simplest type of pointing & is extensively used, as it does not provide any space for accumulation of dust, water, etc.

  6. 2. STRUCK POINTING • In stuck pointing, the mortar is first pressed into the raked joints & then of the joint is pressed in inclined manner by 3 to 6 mm. with the pointing tool. • This pointing drains of water easily.

  7. 3. RECESSED POINTING • Recessed pointing is done by pressing the mortar back from the edges by 5 mm or more. • The face of the pointing is kept vertical, by suitable tool. The pointing gives very good appearance.

  8. 6. V- GROOVED POINTING • V-grooved pointing is made by forming v-shaped groove in the flush finished face, with suitable tool.

  9. Types of pointing:

  10. 4. RUBBED, KEYED & GROOVED POINTING • Rubbed, keyed & grooved pointing, the mortar is pressed into the raked joints & finished flush with the face of the wall & then a groove is formed by pointing tool.

  11. 7. WEATHERED POINTING • Weathered pointing is made by forming a projection of V-shaped; with suitable tool.

  12. Types:

  13. 5. BEADED POINTING • Beaded pointing, the mortar is pressed into the raked joints & finished flush with face of the wall & then the beading is formed by suitably shaped tool along the centraline of the joints.

  14. 8. TUCK POINTING • Tuck pointing , the mortar is first pressed in the raked joints & finished flush with the face of the wall & then the top & bottom edges of the joints are cut parallel so as to have a uniformly raised band about 6 mm. high & 10 mm. in width.
