Product Information

Full details

The Knauf Wallboard Tapered Edge Plasterboard is designed for professional builders and DIY enthusiasts looking to create efficient, smooth interior wall and ceiling surfaces. These 9.5mm boards provide a lightweight solution that is particularly effective for ceiling installations, though their reduced thickness means they are not suitable for high-impact load-bearing applications. This 8-pack is optimized for standard stud spacing, ensuring minimal waste and a professional finish when finished with tape and jointing compound.

FAQs

Can I use these boards in a bathroom?

These boards are standard wallboards. For high-humidity areas like bathrooms, we recommend using moisture-resistant plasterboard instead.

What is the best way to cut these boards?

Use a sharp utility knife to score the paper on one side, snap the gypsum core along the line, and then cut the paper on the reverse side.

Are these boards suitable for fire protection?

This is standard wallboard. If specific fire rating regulations apply to your project, you must use fire-rated plasterboard variants.

How many screws should I use per board?

Typically, screws should be spaced at 300mm intervals along the stud lines to ensure structural integrity and a flat finish.

Can these be fixed directly to masonry?

Yes, they can be fixed using a dot-and-dab method with approved drywall adhesive, provided the masonry wall is clean and stable.

Troubleshooting

Screw heads puncturing the paper surface

Adjust the depth-stop on your screwdriver or use a dedicated drywall dimpler bit to prevent the screw from sinking too deep.

Cracking at the joints after finishing

Ensure the boards are screwed firmly to the studs at the recommended 300mm intervals and ensure the framework is not flexing.

Pros and Cons

Pros

  • Lightweight design eases installation overhead
  • Tapered edges simplify joint finishing
  • Aligned with standard construction stud spacing
  • Smooth finish suitable for various decorative treatments

Cons

  • 9.5mm thickness is not rated for heavy-duty structural support
  • More prone to surface denting than 12.5mm alternatives
  • Requires careful handling during transport to prevent edge damage

Setup, Compatibility & Care

To install, position the boards horizontally or vertically across your studwork, ensuring the tapered edges meet at the joints. Use a dedicated drywall screwdriver set to the correct depth to prevent the screw head from breaking the paper surface of the board. For storage, keep the boards flat and raised off the floor on timber spacers to prevent moisture absorption and edge damage. Avoid storing in damp environments or directly against wet brickwork, as gypsum products are sensitive to prolonged moisture exposure.
