Which are different types of plastering for construction work?

1. Sand faced plaster:

• The first coat of sand faced cement plaster is done with cement mortar in 1:4 with coarse sand after curing the plaster for seven days the second coat of cement plaster 1:3 ratio will be done on the first coat.
• Sponge is used in the second coat and it is applied when the second coat is wet, it is thus worked that the density of sand grain appear on surface is equal and uniform.
• The surface is kept well watered at least for 15 days.

2. Rough Cast Plaster:

• This plaster is a mixture of sand and gravel in specified proportion dashed over a freshly plastered surface.  
• The plaster base consists of two coats, under layer 12 mm thick and top layer 10 mm thick having the cement mortar ratio 1:3.
• In order to make the base more plastic, about 10% of hydrated lime by volume of cement shall be added while prepare mortar.

• It is similar to rough cast finish except clean pebble of size from 6 mm to 12.5 mm are dashed against the surface so that there are laid in position by mortar applied already. 

• This finish is just similar to sand faced finish except fine grained sand is used instead of coarse sand.
• No sponging is done to expose the sand grain .
• It is normally done on internal walls.

• This is just another form of rough cast finish.
• The rendering coat of 12 mm thick is prepared as in case of pebbled dash finish.
• While this coat is wet, pieces of gravel are pressed with hand on the surface.
• Thus it is possible to have beautiful patterns and ornamental designs on the surface by selecting materials of different colors.

• This plaster is done in two layers, under layer 12 mm cement plaster in 1: 4 ratio.
• This is furrowing the under layer with scratching tools applying cement slurry on the under layer at the rate 2 Kg. cement per SQM and on the top layer 1d5 mm cement plaster 1:0.5: 2 ( 1 cement : 0.5 coarse sand : 2 stone chipping 10 MM nominal size. ) in panels with groove all around as per approved pattern including washing the top layer with brushes and water to expose the stone chipping .

• This plastering is normally 18 mm --------- with Terrazzo finish, rubbed and polished under layer 12mm thick plaster 1:3 and top of 6 mm thick white, black, chocolate l, gray , yellow or green marble chips of 3 mm laid in cement marble powder mix 3:1 by weight in proportion 4:7 marble powder mix cement 4 : 7 marble chips .

• This plastering is normally done by Dholpur stone.
