Types of Gypsum Plasters

Levelling plasters

Levelling plasters are applied onto uneven background surfaces. The aim of applying this type of plaster is to ensure a level and plumb substrate. These applications normally call for thicker application of product (10mm+). Examples of this type of plaster would be plasters applied to raw brick and block or concrete to obtain a level and/or plumb surface. For use on internal walls only, must not be used externally.

Finishing Plasters

Two types of finishing plasters can be differentiated:

  1. One Coat Multipurpose

One coat plasters provide levelling and finishing in one application. These plasters are applied onto uneven surfaces. Applying this type of plaster ensures a level and plumb substrate and provides a smooth surface finish. These applications normally call for thicker application of product (10mm+).

  1. Skim Plasters

Skim finishing plasters are applied to even surfaces. These plasters provide a smooth finish to a pre-levelled and plumbed surface.These applications range from fine skim finishes of 2mm to skim finishes of 3-6mm.

Products: Gyproc CreteStone and Gyproc RhinoLite Projection Plaster for RhinoBoard

List of benefits:

  • Gypsum plasters superior smooth finish
  • Can be floated up to 1 hour after application (does not apply to CreteStone/RhinoLite Projection Plaster for RhinoBoard).


  • Sand/cement weight +- 22kg/m2  at 12mm thickness.
  • RhinoLite weighs +- 9kg/m2  at 12mm thickness. Results in less effort/m2
  • Reduction in transport costs to site.
  • Reduction in on-site labour, particularly in high-rise sites. (the weight to be moved around the site or up to various floors has been halved).
  • Much more acceptable to artisans as it is easier and lighter to work with.
  • In bags – just add clean cold water.


  • Coverage can be achieved up to 50% more rapidly than with sand/cement plaster applied manually.
  • RhinoLite is easy to mix, requiring less labour to be ready for application.
  • RhinoLite cures more rapidly than sand/cement plaster, reducing waiting time before painting.
  • Project costs are reduced, as work is completed in less time.
  • Contractors can complete more projects within a year, as time per project is reduced, increasing profitability

Note: All results are based on laboratory trials. All covering capacities were tested under controlled conditions.
