Cornice cement
Cornice cement: a fast-setting gypsum compound used to fix cove cornice to plasterboard at wall-ceiling junctions in Australian residential construction.
Ask Chalkline about this →Cornice cement is a gypsum-based setting compound used to bond gypsum cove cornice to plasterboard or fibre-cement wall and ceiling surfaces. It is a setting-type compound (not a drying-type), meaning it cures by chemical reaction rather than water evaporation, which gives it stronger adhesion than general joint compound. It also fills and finishes mitre joints and small cornice repairs.
Gyprock Cornice Cement is available in working-life variants of 45, 60, and 90 minutes. Mix to a creamy, butter-like consistency with clean water. Apply to both contact flanges (wall face and ceiling face) of the cornice, press into position, clean excess immediately, and secure with temporary screws while the cement sets. After 2 hours the temporary fixings can be removed and screw holes filled. Cornice cement is not suitable for bonding EPS or XPS foam cornice; use a compatible foam adhesive for those materials.
Also known as: cornice adhesive, cove adhesive, cornice bond.
