The following plastering techniques may be applied for a quality work:
- The prepared surface is washed well with water and kept for sufficient time before plastering.
- The type of plaster is decided and mixed as discussed earlier.
- It is preferable to apply the plaster by throwing it with force against the place or surface to be plastered.
- If the surface is very much uneven a preliminary rough coat is applied to make it fairly even.
- Screeds are developed with the help of plumb bob to act as gauges to obtain uniform thickness of mortar.
- The mortar is dashed against the surface between screeds and levelled using floats and straight edges.
- The final finish is obtained with trowels and the surface is watered for about 7 days.
- For surfaces which need two coats, the first coat is made as discussed in steps up to 6 and then the surface is roughened.
- The roughened surface forms a good seating for the second coat and the surface is watered for 2 days.
- After this, the second coat is applied with a thickness of about 3 mm and the surface finished with trowel and is watered for about 7 days.
