Gypsum plaster has been a key construction material for centuries. It’s known for its versatility and is often used on interior walls and ceilings. Let’s dive into its composition, how it’s made, and the different types available.
Gypsum rock is the foundation of gypsum plaster. It’s a mineral made of calcium sulfate dihydrate (CaSO4:2H2O). You can find gypsum deposits all over the world, including the U.S., Russia, and Brazil.
The soft, white or grey rock is mined from the surface. This process is essential for making gypsum plaster.
To make dry gypsum powder, gypsum rock is heated to remove water. This creates a fine, powdery substance. When mixed with water, it turns into a paste that hardens fast.
Synthetic gypsum, a byproduct of industrial processes, is also used. This makes plaster production more sustainable.
There are two main types of gypsum plaster:
Both types have special properties like fire resistance and sound insulation. The choice between natural and synthetic gypsum depends on the project’s needs and environmental impact.
Gypsum plaster has a long history, dating back over 5,000 years. The ancient Egyptians used it in the pyramids, showing its strength and flexibility. The Romans then used it for temples and public buildings, solidifying its role in architecture.
Today, gypsum plaster has evolved into plasterboard and drywall. These changes have greatly sped up construction. Drywall, in particular, is now a big part of the global construction market, making up about 25% of it.
Internal plaster is now used for more than just walls. Fire-resistant gypsum boards are crucial for safety in homes and businesses. They can also cut down noise by up to 80%, perfect for soundproofing.
Gypsum products are also good for the environment. They can be recycled and often include recycled materials, fitting into green building standards like LEED. Gypsum also helps keep buildings cool, which can lower energy use by 10-20%.
Gypsum plaster is also key in modern office design. It allows for easy changes in office layouts, fitting the needs of today’s workspaces. Its long history and eco-friendly nature make it a vital part of construction and design.
Gypsum plaster has many advantages in construction. It’s a favorite among builders and homeowners. Let’s look at what makes it stand out.
Gypsum plaster is great at resisting fire. It can handle temperatures up to °F (537°C) for a long time. This slows down flames, making buildings safer and giving people more time to get out in emergencies.
Gypsum plaster is also good at keeping temperatures steady and blocking sound. It keeps buildings cooler in summer and warmer in winter, saving 20-30% on heating and cooling costs. It also cuts down sound by up to 50%, making spaces quieter and more comfortable.
Gypsum plaster is easy to use, saving time and money. It dries fast, so you can paint in just 72 hours. Unlike cement plaster, it doesn’t need water curing, saving a week of work. Its smooth finish means you don’t need extra steps, saving 30% in time and effort.
Gypsum plaster is good for the environment. It’s recyclable and can be used many times, with 90% of it being recyclable. Using it reduces construction waste by 15-20% compared to old methods. Its low density also makes it a green choice for building.
Gypsum plaster has many benefits, but it also has some downsides. It’s a common choice for inside walls, but there are things to think about before using it.
Gypsum plaster doesn’t do well with moisture. It’s not good for outside walls or places with a lot of humidity, like bathrooms. If it gets wet, it can weaken and even break.
Because it’s sensitive to moisture, gypsum plaster is best for inside use. It’s not good for outside or places that get wet often. This makes it less useful in building projects.

Gypsum plaster lasts about 3-4 months after it’s made. Storing it right can make it last up to 6 months. But, it’s still shorter-lived than many other building materials. This means it might get wasted if not used quickly.
Gypsum plaster sets fast, which is both good and bad. It needs skilled people to apply it right, because it dries in just 25-30 minutes. This quick setting can be hard for beginners to handle.
Applying gypsum plaster well needs focus and known methods. This guide will show you how to get a smooth finish and durable results.
Make sure the surface is clean, dry, and dust-free before applying gypsum. Take off any loose paint or old plaster. Apply a primer coat and wait for it to dry fully for the best stick.
Mix gypsum with water at a 2:1 ratio. Mix well for 1-2 minutes for the right consistency. Use room temperature water. Spread the plaster evenly, keeping it 5-10mm thick for walls and up to 5mm for ceilings.
Let the gypsum plaster set for 40-60 minutes after applying. Water curing is key; mist the surface lightly every 3-4 days for 3-4 days. Use a trowel or sandpaper for a smooth finish when it’s semi-dry. It takes 2-4 weeks to fully dry, depending on thickness and environment.
Using the right application methods means gypsum plaster can last over 50 years. It also offers great sound insulation and fire resistance.
Gypsum plaster has some big advantages over old favorites like cement and lime plaster, though it’s worth considering the durability of lime plaster in certain applications. It dries fast, setting in 25-30 minutes and drying in just 3 days. Sand cement plaster, on the other hand, takes about 21 days to dry completely.
Using gypsum plaster is quicker. You only need one coat for a smooth finish, unlike cement which often needs more. Plus, gypsum is lighter, which means less stress on buildings compared to cement plaster.
Portland cement plaster is known for its toughness and ability to withstand the weather, making it great for outside use. But gypsum plaster is better at resisting fire and keeping buildings cool, which could save on heating and cooling costs.
Gypsum plaster has many perks, but it costs more than cement for the same thickness. Cement is still a budget-friendly choice for big projects, even if it takes longer to install. The choice between gypsum and traditional plasters depends on what you need for your project, like the area, budget, and finish you want.
Gypsum plastered walls are very durable if you take care of them. They can last over 50 years with the right care. This part talks about how to keep them looking good for a long time.
Keeping gypsum plastered walls in top shape is important. You should check them often for cracks or water damage. Use a soft, dry cloth to clean them without harming the surface.
Gypsum plaster can still have problems. Water damage is a big one, mainly in places like bathrooms and kitchens. Using special gypsum boards in these areas helps a lot. For areas that get a lot of use, adding fiberglass mesh to the plaster makes it stronger.
Here are some ways to make your gypsum plaster last longer:
By following these tips, you can make your gypsum plastered walls last a long time. This keeps your home looking great for years to come.
