Wall Plastering
This is a finishing method whereby the rough concrete surface of a wall or ceiling is made smooth. It begins with spreading wet cement and an appropriate device is used to level the surface. Plastering is necessary for painting and facilitates decorative techniques. A plaster is a thin layer (0.3 cm or less) which may be applied about three times depending on the nature of stone used on the wall. There are various types of wall plasters with contemporary designs featuring beautiful bricks.

​Cement
Cement and water, and sand are mixed in the desired ratios and a plasticizer added. This is a liquid that makes the plastering process easier.

Gypsum
This plaster is applicable in naturally occurring materials and is normally applied as a finishing coat or an under-coat. It is very effective at preventing cracks and shrinkage. Depending on the manufacturing process, gypsum plaster comes in many designs. And according to the application, gypsum can be an undercoat, a finish, casting, or machine-applied plaster. 

Lime 
It consists of lime and sand mixed in the ratio 3:1 respectively. It either used as an undercoat of a finishing coat. It is prone to shrinkage once it dries and this can be avoided by applying animal fur. Lime plasters are common wall finishes in ancient structures.

The following are types of plaster finishes:
  • Smooth Cast Plaster
Cement and sand are mixed in the ratio 1:3. Only fine sand is used in the preparation of this mortar. A wood float or skimming float is used to spread the plaster, creating a level and smooth surface. 
  • Spatter Dash
This is a rough plaster finish whereby coarse aggregate, sand, and cement are mixed in the ratio 1: 3: 1.5. The coarse aggregate used is 3-12 mm thick. This mixture is scooped with a trowel and applied on the wall; then leveled with a wooden float.
  • Scrapped Finish
A final plaster coat of 6-12mm thickness is applied and allowed to cure. Then a scraper or steel blade is used to rub off about 3mm of the plastered layer. This finish is very hardy and crack-resistant. 
  • Textured Finish
This is stucco plaster which features various textures and geometric shapes on the last coating. Different tools are used to obtain such shapes.
  • Pebble Dash 
This consists of a 12mm thickness layer of sand and cement in the ratio 3:1. Once the mortar is spread on the wall, pebbles of 10-20mm are sprinkled over the plastered surface. They need to be pressed with a wood float gently. Pebbles make beautiful walls once they harden on the wall surface. 
  • Depeter Plaster 
It is similar to pebble dash only that gravel is used instead of pebbles. 
  • Sand faced Plaster 
In this finishing design, two coats are applied. The first one is a 12mm thick plaster made of sand and cement (4:1) and applied in zigzag designs. Then it is left to cure for a week. A second coat (8mm thick) is applied with equal proportions of sand and cement and leveled with a sponge. Screened sand is then applied with a wood float. That is how sand faces plaster finish is obtained. 

How Different Surfaces Affect Plaster Application?
The kind of plaster to be used depends on the type of wall set for plastering. Rough solids such as bricks have high mechanical adhesion once plaster applied. Smoother bricks of high density are porous and absorb water which is a necessary factor for joining plaster to the surfaces through suction. Suction is the degree with which the smooth surface absorbs water to help in adhesion. Lightweight concrete possesses a high suction power which deters proper attachment of plaster. It is thus recommended to reduce the water absorption capacity using a liquid primer or adding more water before a wall is plastered. For walls with low suction, bonding agents like polyvinyl acetate (PVA) is brushed before plaster is applied immediately while it’s still sticky.
