Gradually add water to the powder while mixing until you achieve a smooth, 'buttery' consistency. Avoid making the mixture too wet, as this can affect performance and drying time.
This filler is suitable for plaster, stone, concrete, and wood. It is designed for use on walls and ceilings.
The filler can fill gaps and cracks up to 40mm deep in a single application.
The approximate drying time is 1-2 hours. This can vary depending on the depth of the fill and environmental conditions.
Yes, once the filler is completely dry and hard, it can be sanded, drilled into, and painted over.
Unmixed powder should be stored in the airtight bag provided in a cool, dry place. Once mixed, the filler cannot be stored.
This product is primarily designed for interior use on walls and ceilings. For exterior repairs, please consult Ronseal's range of exterior fillers.
This may occur if the fill is too deep (over 40mm) or if too much water was used during mixing. For deeper fills, apply in layers, allowing each layer to partially dry. Ensure the correct water-to-powder ratio is used.
Ensure the surface is clean, dry, and free from dust, grease, and loose material before application. For porous surfaces, a mist coat of water may help improve adhesion.
Ensure the filler is completely dry before attempting to sand. If it remains soft, it may indicate an incorrect mixing ratio or insufficient drying time. Use fine-grit sandpaper.
Mixing: To prepare the filler, gradually add water to the powder in the bag while mixing until a smooth, 'buttery' consistency is achieved. Avoid making the mixture too wet.
Application: Use a clean filling knife to apply the mixed filler. Press firmly into the crack or hole, ensuring good contact with the surface. Smooth off the excess filler to match the surrounding surface.
Drying: Allow 1-2 hours for the filler to dry. Drying time may vary depending on the depth of the fill and ambient conditions (temperature, humidity).
Compatibility: Suitable for use on plaster, stone, concrete, and wood. It can be drilled once completely dry.
Care: Store any unused powder in the airtight bag provided in a cool, dry place. Once mixed, the filler cannot be stored.
