Important Things You Need To Know About Lime Plaster

There are a lot of misconceptions and erroneous perceptions by people when it comes to lime plaster. It remains to be one of the most misunderstood plastering materials. In fact, a lot of people confuse it for the other plastering materials. Thus, there is a need for us to separate the fact from the myth in as far as this plastering material is concerned. A lot of people commit the mistake of associating lime plaster with any mortar that has lime component. Unfortunately, such perception is grossly erroneous. In most cases, this type of mortar does not have lime plaster and the mixture is actually what we term as ‘stucco.’

Lime plaster can be created by mixing calcium hydroxide with an aggregate such as sand. This hydration product reacts with carbon dioxide and turns into calcium carbonate, which is basically limestone. This solidified form is what is attained when you use lime in your plasterworks. You can create a perfect lime plaster mix by properly combining the powder compound with the correct proportion of inert material such as sand. The solidification process is activated when the mixture makes contact with water.

However, if cement is added to the lime plaster mix, the physical as well as the chemical processes are drastically altered. Specifically, the presence of cement in the lime plaster mix will have a direct effect on the porosity, elasticity, colour and final appearance of the plasterwork. In most cases, plasterers carefully manage the proportion of cement in their lime plaster mix in order to reduce its effects on the final lime plaster mix.

Lime plaster is a flexible and functional plastering material. This plastering mix is highly preferred for frescoes. The desired colouring and surface finished is attained with the use of water soluble pigmentation elements. This colouring material is simply applied on the surface that has just been applied with plaster mix.

There are a lot of advantages when you use lime in your plasterworks. In the face of rapid industrialization, lime plaster comes out to be more a more beneficial option to the other types of plastering materials. Here are some of the major reasons why most plasterers prefer to use lime plaster over the other types of plastering materials.

Lime helps reduce the carbon dioxide emissions in the environment. Researchers have shown that by using lime plastering material, we can help reduce the carbon dioxide emission in the atmosphere by as much as 80 percent. When we shift to lime plaster, we help prevent the release of carbon dioxide into our atmosphere thereby giving us a healthier and cleaner environment.

Lime plaster is an extremely flexible plastering material. It has self-correcting properties and can automatically adjust to minor movements before setting. Thus, plasterers can easily work on and manage their plasterwork with a lot of time to spare.

Since this type of plastering material does not set as quickly as the other plastering materials, you can easily correct and manage the final coat for any changes as a result of movements in your structure. While the lime plaster carbonates, cracks are automatically eliminated as water is drawn from the atmosphere by the lime plaster.
