The Building Process

Some plasterers will stick plasterboard onto the block walls "freehand" i.e. using their skill to make the boards plumb (or otherwise). What is shown below is a technique to make sure that the boards are absolutely plumb and also flush with each other.

	Pads made from plasterboard offcuts can be stuck onto the wall, with a builders adhesive, top and bottom. A straight edge and spirit level is used to ensure that the pads are plumb. Once the adhesive is dabbed onto the walls, the plasterboard is applied and tapped onto the pads with a long straight edge. Once the board is against the pads then the board is plumb. An 8 foot straight edge is also used to ensure the pads are in-line horizontally before any plasterboard is put up.
The boards are supported on timber pieces to raise them about 75mm from the block and beam floor - to accomodate the finished floor level (FFL) and get a tight fit to the ceiling boards at the top. To the right, a blue packer has been added to the bottom pad to bring the pads out plumb.
	To the left, a close up of a pad sited above a doorframe - the pad will support both the plasterboard head and the sheet to the right.
