How to plasterboard a corrugated iron shed

Updated February 21, 2017

Attaching plasterboard to a corrugated iron shed transforms a dreary interior into a home-from-home space. If you enjoy using the shed as a base to potter in the garden while stopping for the occasional cuppa, then smartening up the interior with plasterboard not only creates a homely feel but improves the shed’s draft insulation. By using plasterboard you create a smooth walled interior that banishes the corrugated look from sight. Following an effective technical procedure allows you to quickly establish an optimum plasterboard installation for your shed.

Add 40cm on-centre vertical wooden studs to extend the corrugated panel internal stud framework. Ensure you fasten a horizontal stud between each vertical stud half way up the height of the shed walls.

Fasten the first panel of water-resistant plasterboard from one of the interior corners of the shed. Use galvanised nails to attach the plasterboard at 30cm intervals into the stud framework. Recess the nail head into the plasterboard without causing the front facing-paper to tear.

Position the next and subsequent panels with a 1/2cm gap from the previously installed plasterboard. Measure and cut a plasterboard panel to fit into areas too small for a standard sized panel, such as around the shed door. Use a straight edge and a utility knife to score through the paper and into the front of the plasterboard and apply pressure to snap the plasterboard at the cut line.

Measure and cut plasterboard joint tape to the length of each joint between two plasterboard panels. Apply the tape over the joint and work from the top of the shed wall to bottom.

Spread plasterboard jointing compound over all taped seams, using a plasterboard trowel. Feather the edges of each joint so that the compound thins to each side of the joint. Cover all nail head recesses with jointing compound so that the plasterboard is smooth.


Using water-resistant plasterboard instead of standard plasterboard extends the life of the gypsum material in a damp outdoor shed.


Wear a respirator when cutting plasterboard to avoid the inhalation of gypsum dust.
