       5.0   METHODOLOGY


The sequence of operations/activities and corresponding method is as follows:


Materials: Cement confirm to I.S.455, Sand  Confirm to I.S.1542, water, 20 gauge G.I  wire mesh  and G.I Nails U type as per E.I.L. specification


Cement, sand, water for plastering/pointing work shall conform to EIL specification. Sand for plastering and pointing shall confirm to EIL spec 6-68-002 Rev. 2 and shall be hard, durable, clean, and free from coatings /organic matters/silt-clay. Fine sand shall be obtained from river beds and shall be clean, sharp and. free from excessive deleterious matter. The sand shall not contain more than 5% of clay and silt as determined by field test with a measuring cylinder. 

Water shall be of potable having   pH value not less than 6.


Tools & Plant  :Trowel, Chisel, Plumb bob,  Aluminum  or  Wooden  rectangular section  of 1.80 meter to 2.10 meter long and spirit level


* Preparation of Cement sand mortar


Cement mortar shall be prepared by mixing cement, sand by volume .Proportion of cement and sand shall be 1:4 (1 part of cement & 4 parts of sand) or as specified/shown on the drawings. The mixing of cement sand mortar shall be done in a mechanical mixer operated manually/by power, or by hand mixing with the prior permission of Engineer-in-charge depending on the quantum, nature and location of work. All mortar thickness are as per Project specification.


Preparation of surface:

The surface shall be cleaned off dust, loose mortar dropping and other foreign matter by water by brushing.

Smooth surfaces shall be roughened by wire brushing or hacking for hard surfaces.

In case of brick/stone masonry, racking of joints shall be carried out wherever necessary.

The masonry work is to be allowed to dry for sufficient time before starting the plastering work.

All RCC Surface are to be hacked or chipped as per specification to ensure proper key for plastering work.

Scaffolding/ Staging :  Scaffolding / Staging  which is to be done as per Project Specification


Application of Plaster:

To ensure even, specified thickness, plaster of 150 mm x 150 mm shall be first applied horizontally and vertically at not more than 2 meter interval over the entire surface to serve as gauges. The surface of these gauged areas shall be truly in the plane of the finished plaster surface. The mortar shall be brought to true surface by working with a wooden straight edge reaching across the gauges with small upward and sideways movements at a time. Finally the surface shall be finished off true with a trowel or wooden float to obtain a smooth texture. Excessive toweling or overworking the float shall be avoided. All corners, arises. Angles and junctions shall be truly vertical/ horizontal and shall be carefully finished. Rounding or chamfering of corners, arises, junctions etc. shall be carried out with proper templates to the size required. In suspending the work, the plaster shall be left. Cut clean to line, both horizontally and vertically. When recommencing the plastering, the edge of the old work shall be scrapped clean and wetted before plastering the adjoining area. Plastering work shall be closed on the border of the wall and nearer than 150 mm to any corners or arises and shall not be closed on the body of the features such as plaster bands, cornices nor at the corners or arises.


For external plaster, the plastering operations shall be started from top to floor and carried downwards. For internal plaster, the plastering may be started wherever the building frame, roofing and brickwork are ready.


In case of Two-layer plaster work, the first layer surfaces to be beaten up by edges of wooden tapers and the subsequent layer shall be applied to the specified thickness after this coat is allowed to set for 3 to 5 days depending on weather conditions. The thickness of plastering shall be as specified in drawing.

 In all Brick / Stone Masonry & RCC joints Wire Mesh of 150 mm width 20 gauge thickness stretched tight & fixed with GI U type nails before plastering.

Any defective work which gives hollow sound shall be cut into rectangular shape and again plastering work to be done as per above.

*  Pointing:


Pointing shall be of the type as shown/specified in the drawings such as flush, cut or weather struck, raised and cut pointing etc.


The joints shall be raked to a depth that the minimum depth from the edge of the Brick/stone shall be less than 20mm.


The mortar shall be pressed into the racked out joints with a pointing trowel according to the specified type of pointing. The mortar shall be spread over the corner edges or surfaces of the masonry and pointing shall then be finished with the pointed tool


       Flush pointing: 

       The mortar shall be pressed into    

       joints and shall be flushed with stone walls. The 

       edges shall be neatly trimmed with trowel.


Cut pointing: 

The mortar shall first be pressed into joints. The top of the horizontal joints shall be neatly pressed back by about 15mm with the pointing tool so that the joint is sloping from top to bottom. The vertical joint will also be similarly pointed. The junctions of vertical joints with the horizontal joints shall be at right angles in case of brick masonry work.


Raised and cut pointing: This type of pointing shall project from the wall facing with its edges cut parallel so as to have a uniformly raised band of about 6mm and width 10mm more as directed. The pointing shall be finished to a smooth but hard surface.

Curing work


Curing shall be started 24 hours after finishing the plaster/pointing work. The plaster shall be kept wet for a min. period of 7 days and during this period the plaster/pointing shall be protected from all damages by suitable means as approved by the Engineer-in-charge. The date of work of plastering/pointing shall be marked on the surfaces to ensure the proper duration of curing.




       All the form work shall be so done that no plastering         or other external finish is required. All burrs shall be         rubbed smooth with carborandum stone and the               finished work shall present a uniform shade and                 finish. All the exposed surfaces shall be provided               with a coat of cement wash free of cost if the                       rendered surfaces are not of acceptable standard as         per the sole. 


Ø Contractor shall ensure that the machine operators involved must be experienced/competent persons.

Ø All PPE is a must in this activity.

Ø It is to be noted that the special care to be adopted against snake/insects bite.
