Frequently Asked Questions
What's the difference between tapered edge and square edge plasterboard?
Tapered edge plasterboard has recessed edges that allow jointing tape and compound to sit flush with the surface, creating seamless joints. Square edge boards are used for overboarding existing surfaces where the joints will be covered by a skim coat of plaster.
How many sheets of 2400mm x 1200mm plasterboard do I need per square metre?
Each 2400mm x 1200mm sheet covers 2.88 square metres. Therefore, you need approximately 0.35 sheets per square metre, or roughly 3.5 sheets for every 10 square metres of wall area.
Is 12.5mm plasterboard suitable for ceilings?
Yes, 12.5mm plasterboard is suitable for most ceiling applications with joists at 400mm or 600mm centres. However, ensure adequate fixing points and consider using ceiling-grade boards for better sag resistance in longer spans.
What tools do I need to cut and install 12.5mm plasterboard?
You'll need a sharp knife or plasterboard saw for cutting, a screw gun or drill for fixing, plasterboard screws, and a T-square for accurate measuring. For finishing, you'll need jointing compound, tape, and smoothing tools.
Can I use standard 12.5mm plasterboard in bathrooms?
Standard plasterboard is not recommended for wet areas like shower enclosures. For bathrooms, use moisture-resistant boards or tile backer boards in areas exposed to direct water contact, though standard boards can be used in dry areas of the bathroom.
