What is the Difference Between Gypsum Plaster and Cement Plaster?

People often get confused about, gypsum plastering vs cement plastering, which one’s better. The best plastering material can keep your walls sturdy, attractive, and protected for a very long period. Plastering can be done using a variety of materials, but the two that are most frequently used are cement and gypsum.

• Cement plaster:

Making cement plaster involves combining cement, sand, and water; typically, the proportion of cement to sand is one to four. Depending on the surface to be plastered, the thickness of the plaster might vary from 12 to 20 millilitres. Plaster is occasionally combined with plasticizers to guard against parasites on walls. 

• Gypsum Plaster:

It is used as a ready-made plaster after being combined with water. It has a powdery appearance and is white in hue. Plastering for walls and ceilings has a different thickness; walls may be as thick as 11 millimetres, while ceilings can only be as thick as 8 millimetres. In order to create various types of plasters, gypsum plaster is also heated at particular temperatures.

Cement plaster vs gypsum plaster- Which one’s better?

• Although each has advantages and disadvantages, cement plaster is the best choice for exterior plastering. Gypsum plaster is often used for interior plastering because it dries quickly and is simple to prepare and level. 

• There are further justifications for selecting gypsum plaster. Contrary to cement plaster, it does not require water curing, saving time and money.

• Gypsum plaster also dries more quickly, so painting and other work can begin instantly. Gypsum-plastered walls already have a decent finish, so there is no need to spend more time and money on further levelling the surfaces.

• Additionally, due to its cost-effectiveness, gypsum is often selected by developers for use in interior plastering. 

• Sand and cement must be mixed in the correct proportions to create cement plaster; if either ingredient is used in excess, the desired plaster texture cannot be achieved. All you have to do to use gypsum plaster is combine it with the appropriate amount of water. 

• Due to its ability to be recycled and used again, gypsum plaster is also a green product. 

• Walls painted with cement occasionally experience cracking or shrinkage after a few months, whereas gypsum plaster lasts a lot longer without issues. It does not imply that it is more durable and stronger than cement.

• When compared, gypsum plaster appears to score higher. Cement plaster, on the other hand, is superior over time simply in terms of durability.

It's important to choose the plaster type based on the specific requirements of your project. Gypsum plaster is preferred for interior applications where a smooth finish and quick drying are essential, while cement plaster is suitable for both interior and exterior projects where durability and moisture resistance are critical.
