Overview:

Toupret Plasterboard Joint Filler is a powder-based jointing compound for plasterboard. It gives you a full 3-hour working window, so you can fill more joints per batch. The formula bonds to gypsum plaster, plasterboard, drywall, and old painted surfaces with no primer or sealer required beforehand. It sets without shrinkage and dries to a white finish.

This jointing filler conforms to BS EN 13963 for plasterboard jointing applications, and it also meets BS EN 16566. Coverage is 1.1kg of powder per m² per mm of thickness, or approximately 250g per linear metre. You can apply a second coat after 4 hours and overcoat with paint or wall coverings within 24 hours.

The product carries a 12-month guarantee from the date of purchase when stored in its original sealed packaging, away from moisture. If you find it to be faulty within the guarantee period, a replacement will be arranged on proof of purchase. For interior use only.

Typical Applications

• Plasterboard jointing: Filling and finishing the joints between boards on new drywall installations.

• Gypsum plaster surfaces: Filling cracks and imperfections in gypsum plaster walls.
• Old painted surfaces: Jointing or patching over previously painted plasterboard without stripping back.
• Pre-decoration preparation: Skimming and finishing boards before painting or wallpapering.
• Multi-joint projects: Larger rooms or commercial fit-outs where a longer working time reduces batching.

How to Use

• Prepare the substrate: Make sure surfaces are hard, cohesive, clean, sound, and dry. Do not apply over damp, frozen, or bonded-coating surfaces. Do not apply over polystyrene.

• Mix the powder: Add 420ml of clean water per 1kg of powder (a 42% mixing rate). Mix to a smooth, lump-free consistency before use.

• Apply the filler: Use a taping knife, putty knife, or trowel to apply the mixed compound to joints or patches. Work at a temperature between +8°C and +35°C with relative humidity no higher than 70%.

• Allow to set: Wait at least 4 hours before applying a second coat. Full drying time before overcoating with paint or wall coverings is 24 hours on average.

• Sand and finish: Once fully dry, sand back to a smooth finish. Wear a P2 dust mask, protective goggles, and gloves when sanding.
