Application Instructions

1. Prepare the surface by ensuring it is clean, dry, and free from loose material.
2. Apply the filler using a filling knife or trowel, pressing it into the gap or hole (build up in layers for holes over 20mm deep, allowing each to dry).
3. Smooth the surface with the knife for a flush finish, minimizing sanding needs.
4. Allow to dry for at least 30 minutes (longer for deeper fills, up to 24 hours in some cases).
5. Sand lightly if needed to achieve a smooth finish, then paint or wallpaper as desired.
6. Clean tools with water immediately after use to maintain their condition.

Care & Maintenance

• Clean up spills or excess filler with a damp cloth before it sets.
• Dispose of unused filler responsibly, following local regulations.
• Avoid applying in wet or freezing conditions to ensure proper curing.
