General Types and Components
Basically, there are three, which are as follows:
- Cement
This is a combination of plaster, sand or fine aggregate, and Portland powder, which serves as the binder. This substance is also called as stucco and is used in rendering or covering brick or stone surfaces to smoothen it and hide uneven textures. Such a mixture can also be used to fireproof interiors and the exteriors of walls and various items like pipes and LPG containers.
- Gypsum
This is more popularly known as plaster of Paris - named as such due to the presence of huge amounts of deposits in a certain hill of the said city. Its derivative is calcium sulphate hemihydrates which, when mixed with water, turns back into the original substance.
- Lime
Its key component is taken from the sedimentary rock of the same name, from which calcium hydroxide is extracted and mixed with sand. The proportion varies from one supplier to the other though. One part lime and three parts of the structural agent is the norm.
Types According to Usage
Plaster can be used for browning, which serves as the base coat on brickworks and other semi-porous exteriors. It can be utilised for bonding on surfaces, like poured concrete for example, that are not that favourable for adhesives. Finally, it can be used for finishing in order to give walls a smoother appearance. This procedure is also known as rendering.
