Advantages and Disadvantages of Gypsum Plaster

Gypsum plaster is becoming a well known material in today’s time. From homeowners to builders, gypsum plaster in India is gaining recognition because of its fantastic features making it a good investment. Gone were the days when people used to apply traditional plastering on the internal walls, like cement plaster. With time, it has been realized that traditional plaster has a lot of disadvantages which can be combated using the best gypsum plaster. But, that doesn’t mean gypsum is spotless. It also carries a few disadvantages, and this blog delves deeper into understanding its pros and cons to a greater extent.

Advantages of Gypsum Plaster 

  • Can be easily sourced

Gypsum is a mineral which is sourced and processed to convert into gypsum plaster. Gypsum rock is heated at high temperatures, mixed with additives, and allowed to be set. And therefore, it can be easily sourced because they are factory-made. Also, the mixture of gypsum plaster in India is available in the form of ready mix plaster, which is easy to apply by mixing the water.  Moreover, there are many gypsum plaster manufacturers and suppliers who deal with different quality gypsum, available both at online and offline stores.

  • Very lightweight

Gypsum is hardened during the process of making. This makes it a very porous material, which varies depending on how hardened gypsum is. Thus, porosity gives it a lightweight. This quality is helpful because it won’t add extra weight to the construction. Porosity also makes gypsum plaster sound-absorbing and gives it a smooth surface.

  • Less setting time 

During the process of making gypsum plaster, it is heated up, evaporating all the water. Due to this chemical process, gypsum plaster is likely to dry quickly once applied. It has a very quick setting time as compared to traditional plaster. It dries up within 3 days, quicker than cement plaster, which takes 21 days. This feature allows the painter to paint as soon as plaster is done, saving construction time. 

  • No water curing 

Because gypsum plaster has an exceptional quality of drying up quickly, it does not need water curing. With that said, after applying gypsum plaster, it requires little attention and care. This makes it very useful to save resources like water and time. Therefore, people suggest applying gypsum plaster as it saves construction time and is good to go with, even with little maintenance.

  • Smooth finishing 

Gypsum plaster is a material with low density and porosity. This porosity is helpful in giving it a smooth finish. Even with gypsum plaster one coat, one can see the smooth and glossy finish. Even on bumpy and uneven walls, they manage to maintain an even tone. 

  • Sustainable 

Another reason why gypsum plaster is the best choice? The reason for the growing popularity of gypsum plaster is because it contributes to sustainability. Gypsum plaster is known for leaving a little residue behind. Also, as it needs no water curing, it saves resources like water, which is again sustainable. 

  • Fire resistant 

Gypsum plaster one coat comes with safety. When gypsum comes in contact with fire, it reduces the spread of flame because it contains crystallized water which evaporates. Because of this, they don’t easily heat up, keeping the wall cool. This also impacts less dependency on heating and cooling devices, saving energy.

Disadvantages of Gypsum Plaster 

The disadvantages of gypsum plaster may not overpower the advantages it carries. However, there are a few of them: 

  • Less water resistance 

Gypsum plaster, as already mentioned, is highly porous. This feature helps gypsum plaster to absorb water and moisture in the atmosphere. Due to this, gypsum plaster is not well suited to apply in wet areas like the bathroom or washroom. Because of these properties, it is also possible that plaster breaks easily, and thus they aren’t always ideal. 

  • Ideal only for interior use

Gypsum plaster can’t be used for exterior purposes because when it comes in contact with water, its durability is affected. Therefore, it is not ideal for exterior use because of moisture and water in the air. Since it’s not waterproof, there are chances that the exterior wall may get damaged and might affect the interior wall too. Hence, gypsum plaster has very limited exterior use.

To sum up, 

Gypsum plaster is a wonderful option which is ideal for interior use or making decorative items. Today, there are numerous gypsum manufacturers and suppliers who are dealing with Indian gypsum plaster, imported gypsum plaster and many other varieties to it. Each of these varieties shares different properties; please read our blogs to know more. Before buying gypsum plaster, ensure its application, cost and the dealer you are buying from, as they impact the quality of gypsum.

Gypsum Plaster Vs Cement Plaster: Which one is Better?

The invention of plaster is a boon to human civilization. Serving its significance since ages, plastering has evolved with time and technology. From shielding the walls to maintaining a smooth finish, plaster saves the wall from climatic or external conditions. In this guide, we will discuss the advantages, significance, and characteristics of two types of plaster, gypsum plastering and cement plastering, to understand which one is better. While both are unique, gypsum manufacturers and suppliers have an edge to introduce new features and that’s why they are different from traditional cement plaster. 

What is plastering? 

Plastering is a technique of applying a thin coat of material to the wall to protect it from external factors like wind, dust, or rain. Plasters are usually a mixture of chemicals, lime, sand, or water. The reason why plastering is essential is because: 

  • Ensures longevity of the masonry work as it becomes a layer to protect construction materials from temperature fluctuations, weather, etc. 
  • Provides smooth surface, eliminating uneven and imperfect surfaces which makes wall easy to paint. 
  • Shields the wall and ceiling from environmental factors like downpour, heat, dust or wind.
  • Plastering can avoid the growth of mildew or spores if done using waterproof techniques. 
  • Gives a sleek and smooth look to walls making it look aesthetically appealing.

Now, diving deeper to understand the distinction between gypsum plastering and cement plastering.

What is cement plastering?

Cement plaster is a mixture of sand, water and cement. Applying a double coat of cement plaster makes a wall solid and durable—the proportion of mixture in cement plaster depends on where the plaster is applied. The combination of cement plaster is also known as cement stucco. 

Advantages of cement plaster 

  • Versatile 

One of the primary benefits of cement plaster is that it is ideal for indoors and outdoors. When outdoors, it can help protect the exterior from harsh weather conditions. When indoors, cement plaster can be helpful in maintaining the finishing of the wall. 

  • Durability 

Cement is considered one of the most durable construction materials, which strengthens any part it is added to. Due to weather resistance, it can stay intact for decades without any harm to the wall.

  • Good bonding  properties 

Cement plaster is easy to set and has good bonding properties that can stabilize the mortar work. Also, the bonding is not affected by fluctuations in temperature, which allows for faster setting times. 

  • Fire resistant 

Cement is not easy to catch fire. Thus, it is fire-resistant and ideal for use on the interior and exterior walls. It offers almost four hours of fire resistance and has low thermal conductivity, thus not transferring heat energy easily. 

Disadvantages of cement plaster

  • Time-consuming 

Cement plaster mixture needs a lot of water work to create a perfect mixture. This increases the work and makes the overall project expensive. 

  • Lead to cracks

The curing period of cement plaster requires sprinkling water. If not done. The plaster will not gain strength and will start developing cracks. 

  • Impermeable to water 

Cement plaster is not permeable to water, which makes it a bad choice for washrooms and bathrooms. Without proper ventilation in such areas, it can lead to the breeding of mold spores or mildew. 

What is gypsum plaster? 

Gypsum plaster is the mixture created by adding water to the readymade powdered form of the POP. It is also known as Plaster of Paris (POP). It is white in colour, which adds spark to the wall. Gypsum plaster is heated at different temperatures to create various types of plaster. 

Advantages of gypsum plaster 

  • Easily available 

Since gypsum is factory-made, it is easily available in stores. Also, the mixture of gypsum is easy to make, which saves time and is convenient. Whereas, cement plaster is difficult to make as materials like sand are not readily available. 

  • Lightweight 

Gypsum is a very lightweight material. This means that the mixture of gypsum is light which does not add unnecessary weight to construction. Thus, they are likely to maintain their shape even in cases of natural calamities. 

  • Dries up easily 

The setting time of gypsum plaster is quicker as compared to cement plaster. It dries up within 3 days, quicker than cement plaster, which takes 21 days. Thus, painting jobs also become easier to start, saving time and resources. 

  • No post curing 

After applying gypsum plaster, it requires little attention and care. Unlike cement plaster, which requires water curing, it increases the usage of water and also manpower. 

  • Smooth finishing 

The finish of the gypsum plaster looks smooth even after a single coat. They are good even on bumpy and uneven walls, giving it an even look. Also, gypsum is easy to apply and doesn’t require a lot of work to set.

  • Sustainable 

Gypsum plaster receives all the praise it gets as it is sustainable in nature. It doesn’t leave a residue behind, reducing the waste and making it a good choice to make. 

So, which one is better? 

When it comes to plaster, there is no one-size-fits-all solution. Each plaster is better for different walls. The idealness of plaster also depends on cost, time, availability of resources and purposes. For interiors and ceilings, gypsum plaster is a better option. However, when talking about the exterior wall, cement plastering is relatively better since it is durable. 

To sum up,

Whatever plastering options you go with, it’s important to consider various factors. Weather, availability of natural resources and purpose are a few factors that affect the choice of plaster.
