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.
