Gypsum Vs Cement - Which Is Better For Plastering & Construction?

by Abhinav G. Movie Enthusiast

Plastering can not only make your building look beautiful but also extend its longevity. When it comes to the types of plasters, there are multiple types out there, namely:

  • Cement Plaster

  • Lime Plaster 

  • Gypsum Plaster 

Out of the three types mentioned above, gypsum plaster is the most popular option out there, followed by cement plaster. These two types of plasters are not only utilised for interior plastering needs but also exterior plastering. They help in creating a protective covering over your building structure (either internally or externally) so that you can continue to use your building for an extended period. 

When comparing cement and gypsum plaster, various merits & demerits can be included for both. But, which one is the better out of the two? Let's find out. 

All About Cement Plaster

According to professional GIB fixers in Auckland, a cement plaster will comprise Portland cement, sand and water. The mixture tends to be homogeneous and the thickness of a cement plaster ranges between 12-20mm. Cement plaster is obtained by mixing four parts of sand & water, along with one part of cement. 


  • It’s highly moisture resistant, unlike gypsum.

  • The cement plaster acts as the first line of defence against external weather agents such as sun, wind, rain and snow. 

  • It can be used for both internal and external walls. 


  • The surface of a cement plaster is rough and uneven. It has to be treated with Plaster of Paris before applying paint. 

  • It can shrink and thereby develop hairline cracks.

  • The curing process takes time (at least seven days).

  • Mould & mildew can easily attack cement plastered surfaces.

All About Gypsum Plaster

Unlike cement, gypsum plaster is white and is mainly available in powdered form. To create the plaster, only water should be added to the mix and it'll be available to be applied directly onto ceiling and wall surfaces. The thickness of gypsum plaster is 11 mm for the walls and 8 mm for the ceilings. 


  • The application of gypsum plaster provides you with a smooth finish that's ready to paint. You don't have to use any Plaster of Paris, unlike cement plaster.

  • Very easy to prepare. 

  • It’s highly resistant to mould & mildew.

  • Compared to cement plaster, gypsum plaster doesn’t shrink much.

  • It's an eco-friendly product since gypsum is obtained naturally. 

  • It only takes 24 hours to dry.

  • Helps in keeping the building warm during winters and cold during summers.

  • It’s resistant to fire.


  • Only suited to be used on the building interiors.

  • Cannot be used in moisture-prone areas.

Thus, it's safe to say, gypsum plaster is surely the best option out there when it comes to plastering.
