Identifying Types Of Plasters

Spread the love

Plaster is a mixture that is used as a protective coating to be spread on walls in buildings. It’s useful for many different reasons, such as insulation, decorations and for moulding reasons. There’s many different types of supplies that deal with plaster and this guide will help you identify which ones are useful for a specific type of situation. There are 4 main types of plasters that are available such as:

Lime Plasters

Lime plasters are a commonly used building product that consists of hydrated lime, water and sand. Lime mortar is along the same lines of the lime plaster. The production is similar but the application for both products differ. Mortar is created by mixing equal amounts of sand and lime with a little bit of cement thrown in for the purpose of increasing the overall tensile strength. Lime plasters contain a sand to lime ratio of 1:3. The plaster can be used as an undercoat. It is useful in the restoration of old structures. This type of plaster is also used to make plasterboards for insulation purposes. A plasterboard installation compromising of lime plasters will make a room soundproof as excess sounds are absorbed by the plasterboard.

Cement Plasters

Cement plasters are a commonly used building product that is better suited to damp conditions. It is generally applied in one thick coat and the thickness may vary with the type of construction it’s used for. Cement plasters are generally made with a cement to sand ratio of 1:4. It is primarily used as an undercoat, a hard background for the construction of brick walls as well as partitions. This type of plaster is also used because of its fire resisting properties. It’s quite commonly used in masonry. This type of plaster can help with insulation when building a house. However, insulation batts Melbourne are also used alternatively for insulating purposes.

Gypsum Plasters

Gypsum plasters are a commonly used building product that’s also known as the “plaster of Paris”. It’s a versatile material that is easily reshaped when mixed with water. It is used as a plaster cast of sorts in constructions and functions similar to clay. This is the same type of material that is used to make casts for people with damaged arms and legs.

Clay Plasters

lay plasters were a commonly used building product that’s composed of clay, sand and water. Plant fibres are also added to increase the overall tensile strength. This type of plaster has been in use since the ancient colonies. Clay plasters were used in the interiors of homes in older American colonies. Since they are lacking in tensile strength, they have fallen out of favour in today’s industry and aren’t as widely used anymore.
