  1. Ensure surfaces are clean, dry and free of loose material.
  2. Using the flexible spatula provided on the lid, press the filler firmly into the crack or hole and smooth off surface; there is no need to overfill.
  3. Lightly sand back any excess filler from the surface after product turns off-white (2 hours for holes up to 2mm deep). If more than 2mm deep, or in cold and humid conditions, expect longer drying times.
  4. Dust off any loose dust before painting with water-based paints. For oil-based paints allow 24 hours before painting.
