It is crucial for us to properly understand and take into account the essential facts about lime plaster when deciding which type of plastering material to use in our home improvement projects. Most of us fail to appreciate the importance and suitability of lime plaster primarily because of the wrong notions and misconceptions about lime. For one, a lot of us mistakenly associate lime with Portland cement. This is grossly erroneous as these are completely two different products. In some cases, people tend to make the mistake of classifying any mortar with lime content as lime plaster. In view of this confusion, it is crucial for us to study the product and distinguish the facts from the myths.

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.

The physical and chemical process can be altered with the addition of cement to the plaster mix. Adding cement to the plaster mix will result to significant changes in the colour, appearance, elasticity and porosity of the plaster. Thus, it is crucial for plasterers to carefully consider the correct proportion of cement and lime in their plastering material.

Lime is considered as a flexible and multi-functional type of material for plastering. It is a highly preferred plastering material for frescoes. Plasterers can usually attain the colouring in their plasterworks by adding the appropriate pigmentation material. This water soluble pigmentation element is usually applied on a freshly plastered and wet wall surface.

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 directly helps in the reduction of the amount of carbon dioxide that is released into the atmosphere. Scientific studies have shown that lime can account to as much as 80% of the total reduction of the carbon dioxide emission in the atmosphere. This means that if you are going to lime as your plastering material for an average-sized home unit, you can potentially prevent the release into the atmosphere an estimated 10,000 lbs of CO2.

Lime plaster has better elasticity than the other types of plastering material. Plasterers prefer to use lime as plastering material as it can be easily managed and worked on. Lime plaster has longer setting time compared to other plastering mix. Thus, you can easily adjust and correct your plasterwork before it finally sets. This distinct feature of lime plaster is very crucial as the setting and hardening process is irreversible and you will not be able to correct and work on the plaster once the process is complete.

Unlike cement plaster, lime plaster has longer setting time. It can easily adjust and adapt to the contours and other physical conditions of the surface of walls and ceilings. While the plaster dries and sets, any developing cracks are corrected without any intervention through the absorption of moisture from the atmosphere. As a result, you can easily attain a smooth and fine finish when you use lime plaster.

Before you can even decide to do any plaster repair, it is important that you are properly oriented and informed of the various alternatives in performing the plastering job. In most instances, DIY enthusiasts will have to go through a special training course on plastering before they will perform any kind of plastering work.

The most logical option for beginners to learn the proper way of doing plastering job is to enroll in special course program on plastering. However, you can also consider the other alternatives if you are looking at a simple patch up plastering job in the wall or ceiling of your home. It is essential for beginners to have an understanding and functional knowledge of plastering.

One of the more important aspects about the task is the proper understanding of the general properties of plaster. Plaster, just like with the ordinary concrete, is a type of hydration product. This means that once the plaster is mixed with water, a chemical reaction instantly occurs. This chemical process, once it begins, is irreversible. As soon as you mix the plaster with water, you will have to maintain a pace in your work so that you are able to finish the plastering before the plaster dries and permanently sets.

There are several powder compounds that you can use in plaster repair. These compounds have varying setting time and it is important for you to choose one that will suit the level of your competency in as far as repair of plaster is concerned. If you are a beginner, then it is not wise for you to use the compounds that are fast setting. You have to remember that the setting and drying process can not be reversed once these powder compounds are mixed with water.

Tiny holes in the plaster of your walls and ceilings can be easily repaired as long as the lath backing remains intact. Under such conditions, you will simply have to mix plaster of Paris with a joint compound to fill the gaps created by the hole. The joint compound slows down the setting process allowing you ample time to work on the Plaster of Paris.

These minor repairs can be easily done if the lath backing of the plaster is still in place. All you have to do is mix the appropriate amount of bonding compound with gypsum plaster and use this mixture to fill up the gaps and holes on your walls and ceilings. However, if there are no more lathe backings to support the plaster, then you will have to improvise one before you can apply the plaster mixture.

To set up the backing for the portion of your plaster that you are working on, you will have to use mesh wire to fill up the opening. Push the wire all the way through the gap and anchor it with the sticks or dowels using tie wires. Apply the joint compound-plaster mix in layers, working each layer and allowing it to set before adding another layer.

Once you are able to completely fill up the gap with the plaster mixture, allow it to set and dry before cutting the tie wire. For beginners and those who don’t have a fair skill in plastering, it is strongly suggested that a joint compound is used instead for the final layer and coat in order to achieve a flat and smooth finish.
