What is the Difference between the Plaster of Paris and White Cement?

The main difference between plaster of Paris and white cement is their composition. The plaster of Paris is made from gypsum while white cement is made from clay and limestone. Cement is also stronger as compared to the plaster of Paris. Let us learn more about their differences below.

Plaster of Paris

Plaster of Paris is made from gypsum. It has a white color and can be purchased in powder form. The plaster of Paris is also called gypsum plaster. To create plaster of Paris, gypsum is burned at high temperatures. As it burns, it converts into a calcium sulphate form. After that, it is grinder in a grinding machine to produce a powder form.

Plaster of Paris has many applications. Aside from casting and molding, it is also used for wall painting. On the other hand, you need to take note that it is only ideal for interior wall painting. Plaster of Paris is also used for painting false ceilings, making sculptures, medical casts, and making decorative items.

White Cement

White cement is similar to grey Portland cement. The only difference is the color and fineness. White cement is determined by its raw materials as well as the process of manufacture. Different substances produce the grey color of the cement. During the white cement manufacture, these substances are kept at the least percentage.

Moreover, clay and limestone is the main material for manufacturing white cement. However, the manufacturing process is similar to that of OPC cement. The only difference is that in the burning process and the fineness of the material.

Can You Add Colored Powder to Plaster of Paris?

The colored powder can be added to the plaster of Paris. Color powder is the best choice, but you can also use paint colorants depending on the project that you are working on. Once the plaster is mixed, you can add the liquid colorants. On the other hand, the colored powder can be mixed with plaster before water is added. This option also offers better color distribution.

Moreover, the colored powder also has options. You can customize the color by mix different colors together. Make sure to test small batches to find out what the final product will look like. The colors are usually lighter, but you can make it darker by adding a finish to the plaster after it has cured.

Cement Plaster Vs Gypsum Plaster

Cement plaster has its pros and cons. While both are strong and durable materials, there are different compositions added which makes them different. Below, we will discuss the difference between cement plaster and gypsum plaster.

Cement Plaster

Mixing cement, sand, and water creates cement plaster. The thickness of the cement plaster usually depends on the surface that needs to be plastered.


Cement plasters can be used for external and internal plastering. It is moisture resistant which makes it ideal for plastering exterior walls. Using cement plaster will protect the wall from the different weather conditions and environmental pollution. Cement plaster is also durable and it helps to strengthen the walls. Moreover, cement plaster is a sturdy base for drilling and will not develop cracks. Hence, it is a good choice for walls that have electrical fittings and wirings.


A disadvantage of using cement plaster is that the surface tends to look uneven and rough. Because of this, it needs an additional process to smoothen it out. Usually, plaster of Paris is added to the plastered walls for a smooth finish. Moreover, cement plastered walls and ceilings need water curing. Otherwise, it will not gain proper strength and can develop cracks. Aside from that, the surface of the cement plastered walls can also shrink and cause hairline cracks.

Gypsum Plaster

Gypsum plaster is a ready-made plaster that can be used by adding water into it. It is in powder form and has a white color. Moreover, it is heated at specific temperatures to produce different types of plasters.


The good thing about gypsum plaster is that it does not need punning or any process to have a smooth surface. This will save you time and money. Moreover, it is available in a ready-made form for easy and convenient use. Because gypsum plaster does not expand or contract, shrinkage is not an issue. It is extracted from gypsum rock and dehydrated to create a powder form.

Another advantage that you can get from gypsum plaster is that it can be recycled and reused. It is a fast-drying material. It is usually used in walls because it has a low thermal conductivity and can keep your home cool. Aside from that, it is also fire and mold-resistant.


A disadvantage of gypsum plaster is that it is only recommended for interior plastering. Take note that this type of plaster is not moisture-resistant and should not be used in damp areas like the bathrooms, basements, or kitchens. Moreover, you should be careful when working with gypsum plaster. It is a soft material and can easily break or develop cracks.
