Relationship Between Cement Plaster And Architectural Plaster

Cement plaster is not just a technical term; it has a meaning, and that meaning serves an important purpose. Cement or other plasters are primarily used in various wall constructions to give walls a stylish finish and to make them as weather-resistant as possible. Plastering and cement plastering in Sydney is an art in every sense of the word, and wall plastering should only be left to experienced foremen or builders. You should also check whether the foreman or construction worker has experience. Lack of experience in such work can lead to many problems, such as poor mixing of concrete and plaster or cement plaster peeling off from the walls within a few years. If the plaster surface is improperly smoothed, air bubbles will form. The foreman must know the exact amounts of sand, lime, and cement needed to mix concrete to plaster or cement a particular wall. This quantitative determination is usually determined by the surface condition of the wall to which concrete is applied. Unlike foam plastering in Parramatta, cement plastering and plastering can be complex operations and require the expertise and skills of an experienced foreman. Here we take a look at the different aspects of concrete plastering and plastering that you and your foreman should always keep in mind.

Lime plaster, which is made only of sand and lime, is originally characterized by being extremely soft and difficult to break. Therefore, to increase its strength and durability, the foreman must mix some cement into it. Cement not only makes the concrete mixture strong and durable but also significantly reduces drying time. If lime is completely replaced by cement, the strength and durability of the concrete mixture will be the highest, and the drying time will be the shortest. However, a concrete mixture consisting only of sand and cement begins to dry as soon as it is mixed and exposed to air, which makes it very difficult to work with, let alone elegantly plaster. Therefore, to mix the perfect concrete mixture, you need to use a portion of lime.
Before applying the concrete mixture to the wall, the amount of sand must also be taken into account. If the ratio of sand is higher than that of cement or lime, the stickiness of the plaster will be affected, resulting in walls where the concrete sometimes flakes off like snowflakes in the winter. Now let's look at the different concrete mix ratios to use depending on the type of surface your foreman is working on.

When applying concrete mixture as plastering or plastering on surfaces of hard clay bricks, concrete blocks, etc., the required mixing ratio is 1:1:6, i.e., 1 part H. lime, 1 part cement, and 6 parts sand. 
For walls that receive heavy rain most of the year, the mix ratio would be 1.75:0.25:6. 1.75 parts cement, 0.25 parts lime, and 6 parts sand. Alternatively, you can mix 1 part cement and 4 parts sand and add lime at a rate of 10% of the total weight of the mixture without water.

Therefore, study the type of wall and carefully choose the type of concrete mixture you need.
