Gyprock Cornice Cement is used for fixing Gyprock cornice at wall and ceiling junctions where the substrate is plasterboard or fibre cement. It is also used for finishing cornice joints and mitres.

Product Overview

Cornice Cement is a setting type compound rather than a drying type that provides superior adhesion with good initial grab and high bond strength.

Three different options are available in the Cornice Cement range, each with a defined setting time for varying job sizes:

• Cornice Cement 45 has a 45 minute working life. This product has an unstabilised setting time that can be accelerated readily by adding a small amount of set plaster such as crushed Gyprock core.
• Cornice Cement 60 has a 60 minute working life.
• Cornice Cement 90 has a 90 minute working life.

Typical Applications

Cornice Cement is typically used for substrates in residential construction. A shorter setting time is sufficient for small projects whereas Cornice Cement 90 is ideal for larger jobs, or where decorative cornice is being installed. This extended working time allows the user to enjoy a longer period between mixes, and also more time to get the finish right for any detailed areas.
