Application Instructions

  1. Ensure surfaces are clean, dry, and free of dust, grease, or old sealant.
  2. Cut the cartridge nozzle at a 45° angle to the desired bead size and load into a caulking gun.
  3. Apply a continuous bead of silicone along the joint or surface, using steady pressure for even application.
  4. Smooth the bead with a wet finger or tool within 5–10 minutes for a neat finish.
  5. Allow to cure for 24 hours (depending on humidity and bead thickness) before exposing to water or stress.

Care & Maintenance

  • Remove excess or uncured silicone with a cloth and white spirit; cured silicone requires mechanical removal.
  • Store unopened cartridges in a cool, dry place below 25°C to maintain shelf life.
  • Ensure proper ventilation during application and curing to avoid inhalation of fumes.
