Way of Curing Plastered Surface
Curing is an essential process in the construction of plastered surfaces. It refers to the maintenance of the moisture content of the newly applied plaster during the initial setting and hardening period. Curing is necessary to ensure the proper bonding of the plaster, prevent shrinkage and cracking, and achieve optimum strength and durability.
The method of curing is determined by factors such as type of plaster, climatic conditions, and surface area to be cured. The following are the three common ways of curing plastered surfaces:
1. Wet Curing:
Wet curing is the most commonly used method for curing plastered surfaces. It involves keeping the plastered surface continuously moist by spraying it with water or covering it with wet gunny bags, hessian cloth or straw. The moisture content is maintained to aid proper hydration of cement and keep the surface from drying out too quickly. Wet curing should be started immediately after the plaster is applied and continued for a minimum of 7-10 days.
2. Chemical Curing:
Chemical curing involves the application of a curing compound to the surface of the plaster. These compounds are available in liquid form and are usually sprayed onto the surface. The curing compound forms a thin film over the surface, preventing the moisture from evaporating and maintaining the required humidity for proper curing. The advantage of chemical curing is that it reduces the labor cost and ensures uniform curing.
3. Steam Curing:
Steam curing is a method used for large-scale construction projects or when there is a tight deadline. In this method, steam is introduced into a temporary enclosure built around the plastered surface. The temperature and humidity are controlled to accelerate the curing process. Steam curing is an effective technique for achieving early strength and reducing the curing time, but it requires special equipment and skilled labor.
It is crucial to ensure that the plastered surface is not exposed to direct sunlight or strong winds during the curing period, as they can cause rapid evaporation and lead to shrinkage and cracking. Also, it is essential to avoid sprinkling water directly on the plastered surface, as it can cause uneven curing and reduce the strength of the plaster.
In conclusion, curing is a vital process in the construction of plastered surfaces to achieve strong, durable, and crack-free walls. The method of curing should be carefully selected based on the specific project requirements and proper implementation of the chosen method is essential to ensure the best results.
Objective of Curing Plastered Surface
The objective of curing plastered surface is to maintain the moisture content of the plaster for a specific period of time in order to achieve maximum strength and durability. This process is crucial for ensuring the long-lasting performance of the plastered surface and is a vital part of the overall construction process.
1. Increase strength and durability: The main objective of curing plastered surface is to increase its strength and durability. Plaster is a mixture of cement, sand, and water, and when it is applied to a surface, it starts to harden and gain strength. Curing helps in this process by maintaining the moisture content and allowing cement to fully hydrate, resulting in a stronger and more durable surface.
2. Reduce shrinkage and cracking: Plaster tends to shrink and develop cracks as it dries. Curing helps to prevent this by keeping the plaster moist and allowing it to dry slowly. This slow drying process helps reduce shrinkage and minimizes the chances of cracking.
3. Proper bonding: Proper curing also ensures a good bonding between the plaster and the surface it is applied to. When the plaster dries too quickly, it tends to separate from the surface, resulting in a weak and poorly bonded surface. By keeping the plaster moist, curing allows it to form a strong bond with the surface, ensuring its stability and longevity.
4. Improve aesthetic appearance: Curing helps in achieving a smooth and uniform surface without any cracks or blemishes. By preventing shrinkage and cracking, it helps to maintain the aesthetic appearance of the plastered surface. This is especially important for decorative plaster finishes which require a smooth and flawless surface.
5. Prevent efflorescence: Efflorescence is a common problem in plastered surfaces where white salt deposits appear on the surface due to the presence of excess moisture. Curing helps to prevent this by controlling the moisture content and allowing it to dry gradually, avoiding any excess moisture that can lead to efflorescence.
6. Protect against weathering: Curing also protects the plastered surface against any adverse weather conditions, especially in the initial stages of drying. By keeping the surface moist, it prevents rapid drying due to exposure to sun and wind, which can result in cracking and weakening of the surface.
In conclusion, the objective of curing plastered surface is to ensure the highest quality and longevity of the plaster, while also maintaining its aesthetic appeal. Proper curing is essential for achieving a strong, durable, and visually pleasing surface, making it an important step in the construction process.
Importance of Curing of Plaster
Curing of plaster is an essential and crucial step in the construction process. It refers to the process of providing moisture and maintaining a specific temperature to the applied plaster for a certain period to ensure its proper setting and hardening. It is done to prevent shrinkage, cracking, and to improve the strength and durability of plaster.
The importance of curing of plaster can be understood by the following points:
1. Prevents shrinkage and cracking: Curing of plaster helps to prevent shrinkage and cracking in the plaster.
