there are different types of plaster. Some are given below:
- sand faced plaster
- bonding plaster
- browning plaster
- rough cast plaster
Sand faced plaster is actually a mixture of cement sand mortar which is applied over brickwork and also works as a damp-proof coat over masonry.
This type of plaster is used to give a finishing touch to a surface let’s say to walls and ceilings. To some extent, it also serves as a sound and thermal insulation material.
It adds a decorative touch to buildings and also provides a sustainable base for the paint colors.
how to apply it
The first coat of the sand-surfaced cement plaster is applied in 1:4 cement mortar ratios with coarse sand. The plastering is left for seven days and then a second coat is applied in a 1:3 cement plaster ratio on the first coat. In the second coating, a sponge is applied on its wet surface and it should be well-watered for at least 15 days.
