You might feel up the creek without a paddle if you need to transport a full sheet of plasterboard but you only have a small car. Strapping the plasterboard to the top of you car isn't a great option because it can easily catch the wind and snap. So how do you get that plasterboard home in one piece? The trick, as Leah from See Jane Drill shows us in this video, is to carefully score and fold the plasterboard without totally breaking it in half. First she measures the halfway point with help from a T-square — 120cm, given that the most common size is 1.2x2.4m — and then scores the back of the plasterboard (the side with the cardboard) with a utility knife. You'd probably want to cut it perpendicular to the length of the sheet, but Leah actually scores it lengthwise to fit in her car. Once you score the back, you then snap the sheet without breaking the protective paper. When you unfold it and actually install it, the plasterboard will still be strong enough as long as you have proper framing to support it.
