How to fix plasterboard

Updated February 21, 2017

Plasterboard allows a wall to be insulated quickly and easily. With a few hours and a handful of nails, you can fix plasterboard to the walls of a room and be ready to decorate. Fixing plasterboard is one of the simpler methods of preparing a wall, compared to floating a wall or cement rendering. It is therefore a suitable job for a novice or anyone interested in DIY but without the time to take on large projects.

Measure the height and width of the doorway, including the door frame, with a tape measure. Make a note of these measurements with a pencil and paper. Draw out rectangles on the back of two plasterboards with heights and combined widths equal to the measurements you noted. Place a straight edge by the first line you drew. Score the plasterboard along the straight edge with the craft knife. Repeat for the other lines.

Fold the plasterboards along the scored lines. Cut the plasterboards at the folds with the craft knife. Remove the rectangles of excess plasterboard. Place the first plasterboard around the door frame. Attach the plasterboard to the wall using a hammer and nails. Use 40mm plasterboard nails spaced at regular intervals. For a secure fastening, the nails must be no more than 5 feet apart along the length and breadth of the board. Repeat for the second board.

Place the next plasterboard beside one of the existing boards. Measure and cut the board to size if it is larger than the space available on the wall, taking any skirting boards or coving into account. Attach the board to the wall with the plasterboard nails. Space the nails no more than 5 feet apart. Continue attaching boards until the wall is covered.


Because a doorway creates a weak point in the plasterboard surrounding it, it is important to start plaster boarding at the door so enough plasterboard can be placed around it to work effectively. However, where there is no door in the wall being plaster boarded, you should begin at one end of the wall and work across. This will reduce the amount of boards that need to be measured and cut to fit the wall.


Where a wall has a squared corner, measure and cut the plasterboard to fit before attaching; don't fold the boards around the corner, as this will leave an air gap behind the board. However, an obtuse corner will take a folded board more easily. Score a line down the back of the plasterboard and fold it along the cut so the board folds easily around the corner.
