BGC Plasterboard recommends that this section should be read in conjunction with the architects’ specifications to determine the Level of Finishes.

BGC Plasterboard should be installed after all preceding trades have been completed.

Ceilings should be installed first. BGC Ceilingboard should preferably be fixed with their long edges perpendicular to the windows or light sources, to obviate unwanted light reflections across the joints.

For the walls, BGC Plasterboard sheets should be laid with their long edges horizontal, to minimise the number of joints as well as light reflections across the joints. This is most important when Finish Levels 4 or 5 are specified.

BGC Plasterboard may be cut by scoring the face side and snapping back away from the score. Then cut the paper on the second side following the original score line. Neat straight cuts can be made using a straight edge.

The cut edges should be sanded smooth to form clean joints.

Control joints should be set at twelve (12) metres maximum, or at construction joints, which ever is the lesser.

Clean down area where cornice is to be applied, remove any excess render or loose material.

Mark a guide line to suite the bottom edge of the cornice (90, 75 or 55 down) and pre-cut lengths as required.

All corner joints, internal and external, are to be mitred. Where butt joints are unavoidable, ensure both ends are prepared to align accurately.

Apply (butter) a 10mm bead of cornice cement to both long edges and ends of the cornice.

Locate cornice to guide lines and temporarily block as required.
Fill mitres, cleaning off excess cement as you go.

Remove temporary blocking after BGC Cornice Cement has set.

Apply second topping coat to mitres and joints as required.

Note: only ever butter one length at a time and install immediately.

Contact surface may require damping down prior to fixing cornice, depending on drying conditions.
