2. Wall Coating Material

Another key function of gypsum is as a wall coating material, particularly in spaces like bathrooms. Its ability to resist water and withstand impact makes it an ideal choice for such applications. Moreover, gypsum is also easier to shape and install compared to traditional bricks. By using gypsum, you can paint the wall without the need for additional blocks.

3. Binding Material

Gypsum is often used as a binding material in cement, plaster, and mortar mixtures as it has stronger adhesive properties on walls compared to other materials.

This material is generally used in powder form, mixed with water to form a paste, which then hardens into a solid plaster layer. This plaster is then used to level wall surfaces and fill gaps or cracks in the building.

4. Home Decoration

Another function of gypsum is for home decoration ornaments. Gypsum can enhance the aesthetics of a room through elements like moldings and ceiling centers. For example, ceilings can be shaped into domes, drop-up ceilings, or other creative designs.

Additionally, gypsum is easy to maintain. If the surface gets dirty or dusty, you don’t need to repaint it, but just wipe it with a damp cloth and dry it off.

5. Partition Panels

Last but not least, gypsum can also be used as a partition panel to divide a single room into several separate areas. These panels are typically made from gypsum combined with other materials like fiber and cardboard. Thanks to its soundproofing properties, the partition not only enhances the room's acoustics but also ensures privacy and comfort for the occupants.

Types of Gypsum

There are various types of gypsum that can be used for your building needs. Each type has different sizes, which also affects its price. For example, thin gypsum is usually more affordable compared to thicker ones. Below are some types of gypsum you can choose from:

1. Regular Gypsum

Regular gypsum is a type of material coated with paper and is commonly used for ceilings in living rooms or other spaces. This material is easy to install using screws, nails, or glue, and is flexible for painting or polishing. Thus, you can customize the ceiling color and appearance based on your preferences.

2. Moisture-Resistant Gypsum

This type of gypsum is coated with wax or silicone to make it waterproof. Therefore, it is ideal for damp areas, such as kitchens, bathrooms, or basements. However, moisture-resistant gypsum is more recommended for walls than ceilings, as it is more effective in resisting moisture exposure.

3. Fire-Resistant Gypsum

In addition to moisture resistance, another type of gypsum has fire-resistant properties. This material is specifically designed to protect against heat and fire by adding fiberglass during the manufacturing process, making it stronger and capable of withstanding high temperatures.

Fire-resistant gypsum is perfect for use in areas such as kitchen walls, around cooking stoves, fireplaces, or outdoor walls that need extra protection against fire risks.

4. Soundproof Gypsum

This type of gypsum is specially designed to reduce noise by absorbing sound, making it highly effective in damping echoes and reverberations in a room.

Soundproof gypsum is often used in spaces that require privacy or quietness, such as bedrooms or music studios. However, this type of gypsum should not be installed in areas with extreme temperatures, as it may affect its durability and material quality.

5. Drywall

Drywall is one of the most popular types of gypsum for walls and ceilings. This type comes in various sizes with smooth surfaces and is easy to finish.

6. Patterned Gypsum

Patterned or textured gypsum has a surface that has specific textures or designs. This material is usually used to enhance the appearance of walls or ceilings, adding attractive and distinctive decorative elements.

7. Perforated Gypsum

Next, there is perforated gypsum, which has small holes and is often used to enhance the ceiling's appearance.

This type of gypsum offers an aesthetic appeal with attractive patterns on the ceiling and improves the room's acoustics by damping sound and reducing echo. If you're looking for a ceiling gypsum that is both aesthetically pleasing and functional, perforated gypsum could be the perfect choice.

8. PVC Laminated Gypsum

PVC laminated gypsum is coated with PVC in various patterns, designed to create a luxurious impression and beautify the appearance of a room. Additionally, this gypsum is easy to maintain and clean, making it practical for use.
