FAQs
What is the primary use for Knauf Square Edge Plasterboard?
This plasterboard is primarily engineered for partitions, wall linings, and ceiling applications in residential construction.
How do I cut this plasterboard?
You can cut it using a score-and-snap technique with a sharp utility knife and a straight edge. Score the paper and core deeply, then snap the board over an edge. A plasterboard saw can be used for more complex cuts.
Is this plasterboard suitable for wet areas like bathrooms?
While the board is rot-resistant, it is recommended for standard residential applications. For wet areas, it should be used in conjunction with appropriate moisture barriers and finishes designed for such environments.
What fixing methods are compatible?
It is compatible with screw installation using drywall screws or with the dot-and-dab application method using Knauf Plasterboard Adhesive.
How does its acoustic performance compare to standard plasterboard?
This plasterboard offers superior acoustic performance compared to standard plasterboard, contributing to better sound insulation.
What are the dimensions of this plasterboard sheet?
The dimensions of this specific sheet are 1800mm in length, 900mm in width, and 12.5mm in thickness.
Can I paint directly onto this plasterboard?
Yes, the ivory paper face accepts direct decoration, meaning you can paint it after appropriate priming.
Troubleshooting
Board is difficult to cut cleanly
Ensure you are using a sharp utility knife. Score the board deeply and decisively. For thicker boards or denser materials, a dedicated plasterboard saw might be more effective.
Joints are not creating a flat finish
Ensure boards are cut square and butted tightly. Apply jointing compound evenly and allow sufficient drying time between coats. Check for any debris trapped between boards before applying compound.
Fixings are pulling through the paper face
Ensure you are using the correct length screws and that they are not over-tightened. The screw head should be just proud of the paper face or slightly dimpled without tearing the paper.
Surface is uneven after plastering or painting
Allow adequate drying time for all layers of jointing compound and primer. Lightly sand between coats to achieve a smooth finish. Ensure consistent application of decorative finishes.
Pros and Cons
Pros
Durable and long-lasting due to rot-resistant and non-warping properties.
Excellent acoustic insulation for improved interior environments.
Easy to cut and install using standard tools, saving time on site.
Compact dimensions enhance maneuverability in restricted areas.
Suitable for a variety of finishes, from plaster to direct decoration.
Cons
The 1.62m² coverage per sheet means more sheets are needed for large areas, potentially increasing waste or handling time.
Square edge profile may require extra attention during jointing for a seamless finish compared to tapered edges.
Primarily intended for interior residential applications; suitability for extreme environments should be verified.
Setup, Compatibility & Care Instructions
Setup & Installation
Measurement & Cutting: Measure the required area. Use a sharp utility knife and a straight edge to score the paper face and core deeply. Snap the board over the edge of a table or similar surface to complete the cut. For intricate shapes, a plasterboard saw can be used.
Fixing: The plasterboard can be fixed using drywall screws or by applying Knauf Plasterboard Adhesive in a dot-and-dab pattern to the substrate. Ensure fixings are appropriate for the wall structure and spaced correctly (typically every 300-400mm for walls and 200-300mm for ceilings).
Finishing: For square edge boards, ensure joints are butted tightly together. Apply Knauf jointing compound and paper or fiberglass tape to reinforce the seams. Allow to dry thoroughly, sand smooth, and apply subsequent coats as needed before decorating.
Compatibility
Jointing Compounds & Adhesives: Fully compatible with the Knauf range of jointing compounds (e.g., Knauf All Purpose Jointing Compound, Knauf Joint Filler) and Knauf Plasterboard Adhesive.
Fixings: Suitable for use with standard drywall screws. Ensure screw length is adequate to penetrate the framing material securely.
Framing Systems: Can be used with timber or metal stud framing systems. Ensure the framing is rigid and meets relevant building codes.
Finishes: The ivory paper face is suitable for direct decoration (painting) or for applying plaster finishes. Always prime the surface before painting.
Care & Maintenance
Storage: Store boards flat on a dry, level surface, away from direct sunlight and moisture. Avoid storing boards on edge.
Cleaning: Clean surfaces with a slightly damp cloth. Avoid excessive moisture, as it can damage the paper face and core.
Repairs: Minor damage to the surface can be repaired using appropriate filler. For larger damage, the affected section may need to be cut out and replaced with a new piece of plasterboard.
