FAQ
What is Gypsum Filler and why use it?+
Gypsum Filler is a fine, powdery material made from calcium sulfate. It's used to fill small gaps, cracks, and imperfections in plasterboard before applying final coats, creating a smooth base for painting or wallpapering. Its lightweight nature reduces the overall weight of the wall.
What thicknesses of plasterboard are available?+
This mid-range selection typically includes 12mm, 18mm, and 24mm thick plasterboards. The choice depends on the specific application – thinner boards for general repairs and thicker ones for more demanding surfaces or areas requiring greater structural support.
How much Gypsum Filler should I buy?+
This depends entirely on the project’s scale. For small patching, 1-2kg might suffice; larger rooms require considerably more – a minimum of 5kg is recommended for most standard plastering jobs. Always calculate your surface area accurately.
What tools do I need to apply Gypsum Filler?+
You’ll need a hawk (a flat tray), trowel, jointing knife, and possibly a pasting table for achieving consistent adhesion. A damp sponge is also crucial for cleaning up excess filler and creating a smooth surface.
Can I use this Gypsum Filler on external walls?+
No, this specific range of Gypsum Filler is designed solely for internal plastering applications. External walls require specialist renders formulated to withstand weather exposure and movement.
How do I prepare the surface before applying the filler?+
Ensure the existing surface is clean, dry, and free from loose debris. Light sanding can improve adhesion. Prime if necessary, particularly over previously painted surfaces, for optimal bonding of the Gypsum Filler.
What’s the best way to apply jointing tape?+
Apply the jointing tape with a slight overlap onto the wet Gypsum Filler and ensure it's firmly adhered before applying the final plaster coat. Use a taping knife to press it tightly into the filler for a seamless finish.
Is this mid-range Plasterboard suitable for ceilings?+
Yes, 12mm to 24mm thick plasterboards are commonly used on ceilings for decorative finishes and applying textured coatings. However, consider ceiling height and structural requirements when selecting the board thickness.
How long does it take for Gypsum Filler to dry?+
Drying times vary depending on humidity and temperature, but typically takes between 24-72 hours for a full cure. Avoid applying any further coats until the filler is completely dry to prevent cracking.
What’s the difference between this product and cheaper Gypsum Filler?+
This mid-range product offers improved strength and durability compared to budget options, reducing the likelihood of crumbling or shrinkage after drying. It also contains additives for enhanced workability and adhesion with plasterboard.
