Whether applied in new builds or interior refurbishments, correct installation determines both structural stability and finish quality. HB Plaster delivers professional Gyprock installation services across Melbourne, combining precision workmanship with full compliance to Australian building standards.
Product
What is Gyprock?
Gyprock, manufactured by CSR, is Australia’s leading plasterboard system. It consists of a gypsum core enclosed between heavy-duty paper liners and is available in sheet lengths of 2400mm to 2700mm, typically 1200mm wide and 10mm to 16mm thick. Known for its versatility and clean finish, Gyprock forms the foundation of interior wall and ceiling systems throughout Melbourne.
Product Range
Melbourne properties benefit from a range of Gyprock options, each suited to specific performance needs:
- Gyprock Plus – Premium standard board ideal for dry areas, offering enhanced strength and light weight.
- Gyprock Aquachek – Moisture-resistant board for bathrooms, laundries, and wet areas.
- Gyprock Supaceil – Ceiling board designed to prevent sagging across wider joist spacing.
- Gyprock Soundcheck – Acoustic board for improved soundproofing in multi-residential buildings.
- Gyprock Fyrchek – Fire-rated board meeting Australian fire separation codes.
Selecting the correct product ensures compliance, durability, and long-term performance.
Preparation
Proper planning is critical before installation begins. Framing should be straight, clean, and structurally sound, with studs spaced at either 450mm or 600mm centres and noggins installed where required. Electrical and plumbing work must be completed prior to sheeting. Sheets should be acclimatised to room conditions for at least 48 hours, allowing them to stabilise with Melbourne’s variable humidity and temperature before installation.
Wall Installation
Correct wall sheeting sets the foundation for a seamless interior. Sheets are positioned with the grey face outward and joints staggered for stability. Fixings should align with stud centres, starting from the perimeter and progressing inward. Screws are typically placed at 300mm intervals, set just below the surface without breaking the paper face. Openings for power outlets or switches are cut precisely with a keyhole saw to maintain clean edges and secure fitting. A 5–10mm gap is left at the base to accommodate skirting boards and prevent compression.
Ceiling Installation
Ceiling installation requires greater precision due to overhead work and load considerations. Sheets are run perpendicular to ceiling joists, with staggered joins for strength. Supaceil or moisture-resistant boards are recommended for areas with 600mm joist spacing or high humidity. Fixings are set at 150mm intervals through the joists and 200mm along the perimeter.
Installation safety is paramount. HB Plaster utilises mechanical lifts and professional-grade scaffolding to prevent strain or overreach, ensuring ceiling sheets are positioned securely and safely.
Joint Finishing
Finishing determines the overall quality of any Gyprock installation. Joints are treated with multiple coats of compound, each sanded and feathered to a smooth, paint-ready surface. Corners receive metal bead or paper tape treatment depending on location. External corners are reinforced for durability, while internal corners are finished with precision to achieve symmetry and clean lines. Sanding follows with progressive grits for a refined texture prior to priming and painting.
Common Installation Errors
Avoiding installation mistakes is vital to long-term performance. The most frequent issues encountered in Melbourne projects include:
- Overdriven Screws – Breaking the paper face and weakening joint strength.
- Insufficient Fixing – Causing ceiling sagging or loose boards.
- Poor Joint Treatment – Leading to visible seams or cracking.
- Inadequate Support – Resulting in movement or deformation over time.
- Incorrect Product Selection – Using standard board in wet zones where Aquachek is required.
Professional oversight ensures these costly errors are avoided.
Professional vs DIY
While small patching or single-room projects may suit skilled homeowners, full Gyprock installation requires experience and correct equipment. Professional installation is strongly recommended for:
- Complete interior fit-outs or large ceilings.
- Fire-rated and acoustic-rated systems.
- Heritage and commercial properties.
- Projects requiring certification or insurance documentation.
Certified installers provide structural assurance, accurate fixing, and high-level finishing that typically exceed DIY results.
Cost Overview
Pricing depends on project scale, ceiling height, and finish specification. On average, Melbourne homeowners can expect professional Gyprock installation costs between $35 and $55 per square metre, inclusive of materials, labour, and finishing. This covers sheeting, jointing, sanding, and waste removal. DIY costs appear lower initially but often increase due to equipment purchases and corrective rework. Transparent quoting ensures clients understand total costs before work commences.
