FAQs
What is the main advantage of the 1800 x 900mm size?
The compact 1800mm x 900mm size makes it easier to handle, transport, and install in confined spaces such as lofts, stairwells, and small rooms where larger boards would be difficult to maneuver.
Can I paint directly onto this plasterboard?
Yes, the ivory paper face is suitable for direct decoration after proper preparation, including applying a plasterboard sealer and primer for the best finish.
What is required to finish the joints?
For optimal results, use Knauf jointing compounds like Knauf Fill & Finish Light or Premium variants, along with Knauf joint tape systems.
How does this plasterboard provide superior acoustic performance?
The dense gypsum core construction of the plasterboard is engineered to absorb and dampen sound waves more effectively than standard plasterboard, contributing to better sound insulation.
Is this board suitable for wet areas like bathrooms?
The gypsum core is rot and warp-resistant, making it suitable for general bathroom use, but it is not a moisture-resistant or waterproof board. For areas with direct water contact, specialized plasterboard should be used.
What tools are needed for installation?
Installation is straightforward and only requires basic tools: a straight edge, a sharp utility knife for cutting, and a fixing method (screws or adhesive).
How should I store this plasterboard?
Store the plasterboard flat in a dry environment and protect it from inclement weather to maintain its condition and prevent damage.
Troubleshooting
Board is difficult to cut cleanly.
Ensure your utility knife blade is sharp. Make a deep score on the first pass and a slightly shallower second pass if needed before snapping.
Joints appear uneven after finishing.
Ensure the board edges are clean and dry. Use sufficient jointing compound and tape, applying evenly. Allow compound to dry fully before sanding and applying subsequent coats.
Minor damage to board edges during handling.
Slightly damaged edges can often be repaired with jointing compound before finishing. For significant damage, consider cutting the board to a smaller, usable size.
Poor adhesion when using dot-and-dab.
Ensure the substrate is clean, dry, and free from dust. Apply adhesive in sufficient dabs to ensure good contact with the board.
