Plastering Walls

Plastering - Using Different Types of Plaster on Walls

Plasters used for building construction come in three main types: gypsum plaster (POP), lime plaster and cement plaster. Apart from building and medicine, plasters can also be used for drawing where it can serve as medium for the painting and in production of marbles.

Plastering buildings have been upgraded over the years but was well documented and popularised during Victorian era. Prior to the use of plasters for decoration, they were mainly used as part of construction where cracks and holes on the walls are covered to avoid insects and other animals from inhabiting such cracks. Clay from soft sand have been used for centuries to plaster and beautify walls in Africa, Asia, North America especially amongst Indian and in other places. There is no state proportion of mixture for plastering materials, but standard procedures should be observed, therefore experts' advice should be sort prior to carrying out plastering of your building.

Plastering with Gypsum

The use of gypsum for plaster work has really revolutionised interior decoration of buildings. This material also known as Plaster of Paris because of its large deposit at Montmartre in Paris is used for intricate design of columns and ceilings, it is not a weight carrying structure and is confined only to decorations. It is a dry powder that when mixed in water will readily harden but unlike cement and mortar, its shape can be changed or modified with the use of sculpture tools and sandpaper.  Conventional method for roofing and ceiling buildings is gradually shifting towards the use of POP for obvious reasons; Shapes and sizes can be fabricated to fit desired taste and fashion. It is fire-resistant and this reduces the incidence of fire outbreak. It is light and therefore can be used on soft materials like woods, plastics etc.

Gypsum Plastering Procedure


Plastering with Lime

This is a chemical mixture of Calcium Hydroxide and sand. When exposed to the atmosphere, Carbon dioxide in the air causes setting of the plaster and thus transforms the Calcium Hydroxide to Calcium Carbonate (limestone).

Cement Plaster

The most popular type of cement is the Portland cement, and it is very suitable for plastering walls, for decoration of interiors and exteriors, but the most important use of Portland cement is:

Cement has very high insulating properties against heat and electricity. It is also fire proof and confers additional strength to steel. Cement takes time to set when used for plastering and this makes it less useful for designing intricate moulds for decoration. Also, due to its weight (heavy), very large chunk can not be applied at a time.

There are very many methods to go about this because there are lots of different plastering techniques for cement.
