A Guide to Plastering Materials and Their Uses

Posted by Ryan 29/05/2018 0 Comment(s)

The application of plaster construction is needed not only to provide a smooth surface, but also to make sure that the wall or structure is durable. In some cases, the material used for plastering can provide an extra layer of protection against natural wear and tear as well as make the surface more resistant to water and fire.

During the early days, plastering and rendering walls were simple. Usually a block or brick layer is covered with a coat of plaster material. These days however, you can find different types of rendering and plaster finish such as: hardwall, board finish, magnetic, multifinish, and spray finish. Here are the most commonly used plastering supplies today:
 

Lime Plaster
 

This mixture is a combination of sand and lime at a 1:3 ratio by volume. Lime plaster is both ideal for undercoating and top finish. Usually, lime plaster is used for restoration of ancient structures.
 

Cement Plaster
 

Cement is popular material used for undercoating. It is usually mixed with sand at a 1:3 ratio by volume. It’s a good material to put over brick or block layers. For easier application, lime can also be added to cement mixture.
 

Gypsum Plaster
 

In many constructions today, gypsum has replaced lime and cement as the plastering material of choice. One attractive characteristic of gypsum is its ability to expand after application, hence, preventing shrinkage and cracks. In addition to this, it is also widely available through natural mining or as a by-product from other industrial production. This material is also highly versatile and can be used for different applications.

Plaster when applied in constructions, can have a variety of finishes and texture. This depends on whether the plaster is applied in exterior or interior surfaces. Textured plaster is often used in exterior surfaces while smoother finishes are desired for interiors. Here are the different types of plaster finishes used today:

•    Smooth cast finish
•    Rough cast finish
•    Sand faced finish
•    Pebble dash finish
•    Scrapped finish
•    Depeter finish
•    Textured finish

In addition to the different types of finishes, plaster composition can also differ in order to ensure air-tightness and moisture control. Sand, lime, and gypsum are the common binding agents. Aggregates such as sand and gravel can be added for structure. There are other components that can be added to the plaster mixture in order to improve elasticity and tensile performance. Some common additives are: hemp, fibreglass fibre and mesh, and many others.

With any job that requires plastering, you’ll need to consider plastering supplies for topcoat, basecoat, and primer. Furthermore, you’ll need to consider the tools that will be used for application.
