Hey there! As a supplier of plastering gypsum, I've seen firsthand the variety of types available in the market. Plastering gypsum is a super useful material in the construction industry, and understanding its different types can really help you make the right choice for your project. So, let's dive in and explore the various types of plastering gypsum.
1. Building Gypsum
Building gypsum, also known as hemihydrate gypsum, is one of the most common types. It's made by heating natural gypsum at a relatively low temperature. This process removes part of the water in the gypsum, turning it into a hemihydrate form.
One of the great things about building gypsum is its quick setting time. Once you mix it with water, it starts to harden pretty fast. This makes it ideal for projects where you need to get things done in a hurry. For example, if you're plastering a small room and want to finish the job within a day, building gypsum is a great option.
It also has good workability. You can easily spread it on walls and ceilings, and it adheres well to the surface. Plus, it has a smooth finish, which gives a nice look to the plastered area. However, it's not as strong as some other types of plastering gypsum, so it might not be suitable for areas that are prone to high impact or heavy loads.

2. Anhydrous Gypsum
Anhydrous gypsum is another type that you might come across. It's made by heating gypsum at a much higher temperature than building gypsum, which removes all the water from the gypsum, leaving it in an anhydrous state.
One of the main advantages of anhydrous gypsum is its high strength. It can withstand more pressure and is more durable compared to building gypsum. This makes it a great choice for areas that need to be more robust, like commercial buildings or areas with high foot traffic.
However, anhydrous gypsum has a slower setting time. It takes longer to harden after mixing with water, which can be a drawback if you're on a tight schedule. Also, it requires more water for mixing compared to building gypsum, and the mixing process needs to be more precise to get the right consistency.
3. Desulfurized Gypsum
Desulfurized gypsum is a by - product of the flue gas desulfurization process in power plants. It's an environmentally friendly option because it makes use of waste materials.
In terms of properties, desulfurized gypsum is quite similar to natural gypsum. It has good workability and can be used for a wide range of plastering applications. It also has a relatively low cost, which is a big plus for many construction projects.
Since it's a recycled material, using desulfurized gypsum can also help you meet environmental regulations and show your commitment to sustainable building practices. However, the quality of desulfurized gypsum can vary depending on the source and the production process. So, it's important to source it from a reliable supplier.
4. FGD Gypsum
FGD (Flue Gas Desulfurization) gypsum is very similar to desulfurized gypsum. It's also a by - product of the desulfurization process in coal - fired power plants.
FGD gypsum has consistent quality if it's produced under proper conditions. It can be used for both interior and exterior plastering. It has good adhesion and can form a strong bond with the substrate.
One of the challenges with FGD gypsum is that it might contain some impurities, such as heavy metals. But modern treatment processes can effectively reduce these impurities to an acceptable level. If you're considering using FGD gypsum, make sure to ask your supplier about the quality control measures they have in place.
5. High - Strength Gypsum
As the name suggests, high - strength gypsum is known for its superior strength. It's made by a special manufacturing process that results in a denser and stronger material compared to other types of plastering gypsum.
High - strength gypsum is often used in applications where high performance is required, such as in industrial buildings, high - rise structures, or areas with extreme environmental conditions. It can resist cracking and deformation better than regular gypsum.
However, high - strength gypsum is usually more expensive than other types. The production process is more complex, and the raw materials might be of a higher quality. But if you need a long - lasting and reliable plastering solution, the extra cost might be worth it.
Comparing with Other Construction Materials
When it comes to construction materials, plastering gypsum has some unique advantages compared to others. For example, compared to Bulk Portland Cement, plastering gypsum has a lower heat of hydration. This means that it doesn't generate as much heat during the setting process, which can reduce the risk of cracking in large - scale plastering projects.
It also has better insulation properties. Plastering gypsum can help keep the indoor temperature more stable, which is energy - efficient. In contrast, cement has a higher thermal conductivity, which means it transfers heat more easily.
Another material that is often used in wall finishing is Wall Putty. Wall putty is mainly used for filling small holes and unevenness on the wall surface and providing a smooth base for painting. While plastering gypsum can also be used for leveling, it has better structural integrity and can be used as a thicker layer for more significant repairs or new construction.
How to Choose the Right Type of Plastering Gypsum
Choosing the right type of plastering gypsum depends on several factors. First, consider the application. If it's for a small interior room with normal usage, building gypsum might be sufficient. But for a commercial building or an area with high stress, high - strength gypsum or anhydrous gypsum could be a better choice.
The budget is also an important factor. High - strength gypsum and some specialty types are more expensive, so if you're on a tight budget, you might want to look at building gypsum or desulfurized gypsum.
The environmental conditions of the project site are crucial too. If the area is humid, you need a type of gypsum that can resist moisture. Some types of plastering gypsum can be treated to improve their moisture - resistance.
