Casting Plaster Manufacture

Cast plaster cornices are usually composed of casting plaster with reinforced glass fibres when required.


For installation advice for cast plaster products, please contact the manufacturer.

Painting and Decoration

Finishes applied to cornice surfaces can have a significant effect on the perceived quality of the installation, particularly where critical lighting conditions exist.

  • Matt finishes minimise imperfection visibility
  • Semi-gloss and gloss finishes highlight imperfections
  • Light colours are less likely to show imperfections

Gyprock recommends paint systems consisting of one coat of a plasterboard sealer followed by two coats of finishing paint. Always follow the manufacturer’s instructions for application and recoating.
