Application Instructions

  1. Surface Preparation:
    Ensure all surfaces are clean, dry, and free from dust, grease, or old sealant. Use a suitable cleaner if necessary.

  2. Cut the Nozzle:
    Cut the nozzle at a 45° angle to the desired bead width and fit to the cartridge.

  3. Apply Silicone:
    Using a caulking gun, apply a steady bead of silicone to the joint.

  4. Tooling:
    Smooth the sealant using a sealant tool or soapy finger within 5 minutes of application for a professional finish.

  5. Curing Time:
    Allow to cure for at least 24 hours before exposing to water. Full cure is typically achieved in 24-48 hours depending on humidity and joint depth.


Care & Maintenance

  • Avoid abrasion or scrubbing directly over the sealant line.

  • Clean with a damp cloth and mild detergent.

  • If mould develops over time due to excessive moisture, clean with a mould remover or replace the sealant.

  • Store unused cartridges in a cool, dry place and use within 12 months of purchase for optimal results.


FAQs

Q: Can I use this silicone around kitchen sinks and worktops?

A: Yes, it is suitable for all interior sanitary applications including sinks, worktops, and tiled areas.

Q: Is this product paintable?

A: No, silicone sealant is not paintable. If painting is required, use a paintable frame or acrylic sealant instead.

Q: How soon after application can I use the shower or bath?

A: You should wait a minimum of 24 hours for the silicone to fully cure before exposing it to water.

Q: Is the mould resistance permanent?

A: The sealant is designed to resist mould growth. However, high humidity or poor ventilation can accelerate mould development over time. Proper ventilation helps maintain performance.
