How to Install Siniat Plasterboard

Installing plasterboard properly is essential for a long-lasting, high-quality finish. This guide walks you through installing Siniat plasterboard on walls and ceilings — whether you're a DIY renovator or a professional tradie.

What You’ll Need

• Siniat plasterboard
• Siniat Acrylic Stud Adhesive
• Utility knife, T-square, and tape measure
• Broadknife (38mm)
• Drill/screw gun or hammer
• Screws/nails (as per timber or steel framing)
• Metal corner bead
• Staple gun, tin snips, and platform ladder
• Plasterboard lifter (for ceilings)

Step 1: Prep the Frame

• Check that studs and ceiling joists are spaced at max 600mm centres.
• Ensure all framing is level and free of nails or grease.

Step 2: Install Ceiling Plasterboard First

• Apply adhesive daubs 200–230mm apart, starting 200mm from the sheet ends.
• Fix the sheet across the joists, avoiding the adhesive when screwing or nailing.
• Secure edges and centres. Stagger joins across sheets and back-block if needed.

Step 3: Install Wall Plasterboard

• Apply adhesive to studs at 300mm intervals (start 200mm up from floor).
• Press sheets into place and fasten along edges and centres with screws or nails.
• Stagger joins across different sheets for strength.

Extra Tips

• Leave a 10mm gap from floor to sheet to avoid moisture transfer.
• Use moisture-resistant plasterboard in bathrooms and laundries.
• Use back-blocking for large ceiling joints to prevent sagging.
• Cut boards by scoring the face, snapping, then trimming the back paper.
