Use Interior
  1. Ensure surfaces are clean, dry and free of loose material.
  2. Exterior surfaces should be primed before application.
  3. Using a flexible filling knife, press the filler firmly into crack/hole and smooth off surface. Permafilla has minimal shrinkage - no need for excessive overfill. For deeper cracks apply in 6mm layers allowing each layer to dry before applying the next.
  4. Allow 2-3 hours to set in 2mm applications, in thicker applications and colder weather allow for longer drying times.
  5. Once completely set, Permafilla can be sanded to a feathered edge for a perfect finish.
  6. Paint with water or oil-based paints after applying an undercoat.
