FAQs

How long does it take for the sealant to fully cure?

The sealant is touch dry in approximately 20 minutes, but it requires over 24 hours to fully cure. Avoid exposing the sealed area to excessive moisture or stress during this full curing period.

Can I paint over this silicone sealant?

Silicone sealants are generally not designed to be painted over. Paint may not adhere well and can peel. It's best to use a sealant that matches the desired final appearance or to mask off areas to be painted before applying the sealant.

What is the main advantage of this sealant over standard silicone?

The key advantage is its specific formulation for resistance to mold and staining, making it ideal for humid environments like bathrooms and kitchens where mold is a common problem.

How much area can one tube cover?

The product description suggests it is enough to cover one bath, two showers, and two sinks, depending on the size of the beads applied.

Is this sealant suitable for outdoor use?

While durable and waterproof, this sealant is primarily formulated for sanitary applications in humid indoor environments. For specific outdoor applications, consult the manufacturer's guidelines or product specifications.

What makes the 'Anti-Mould' feature effective?

It contains specific additives that inhibit the growth of mold and mildew. This provides long-lasting resistance to fungal growth and associated staining.

Can I use this sealant in a kitchen splashback area?

Yes, it is suitable for kitchen splashbacks, especially around sinks, to provide a waterproof and hygienic seal that resists grease and food stains, as well as mold.

Troubleshooting

Sealant not adhering well

Ensure surfaces were thoroughly cleaned, dried, and free from dust, grease, or old sealant before application. Surface preparation is critical for adhesion.

Mold appears shortly after application

This sealant is designed to resist mold. If mold appears, it may indicate significant moisture ingress from a faulty seal elsewhere, or the surface was not adequately prepared/cleaned prior to application. Check for and address underlying moisture issues.

Difficulty achieving a smooth finish

Practice applying a consistent bead. Use a wet tool (finger or spatula) dipped in soapy water to smooth the bead immediately after application before it starts to skin over. Work in manageable sections.

Sealant is too sticky/difficult to tool

Ensure you are tooling the bead immediately after application, within the first few minutes before the tack-free stage is reached. Using a smoothing tool dipped in a little water can help.

Pros and Cons

Pros

  • Provides excellent and durable waterproofing for wet environments.
  • Effectively resists mold and staining, maintaining aesthetic appeal.
  • Easy to apply with a fast tack-free time for efficient work.
  • Low odor and low VOC content for a more pleasant user experience and better air quality.
  • Strong adhesion to various common building substrates.

Cons

  • Fast tack-free time may require quick work, potentially challenging for beginners.
  • Requires a full 24+ hours for complete curing, during which it should not be exposed to excessive moisture or stress.
  • While easy to apply, achieving a perfectly smooth finish might require practice.
  • Specific surface preparation is crucial for optimal adhesion, which adds a step to the process.

Setup, Compatibility & Care

Setup:

  1. Surface Preparation: Ensure surfaces are clean, dry, and free from dust, grease, and old sealant. For best adhesion, surfaces should be sound.
  2. Application: Apply using a standard sealant gun. Cut the nozzle at an angle to achieve the desired bead size. Apply a continuous bead of sealant, ensuring good contact with both surfaces.
  3. Finishing: Smooth the bead immediately after application using a wet finger, spatula, or smoothing tool. Remove excess sealant promptly.

Compatibility:

This sealant offers excellent adhesion to a wide range of substrates including glass, ceramic tiles, aluminum, painted surfaces, and many plastics. It is designed for use in sanitary applications. Avoid contact with certain metals like copper or brass in its uncured state. Test on a small, inconspicuous area if unsure about substrate compatibility.

Care:

  • Cleaning: Clean application tools and any excess sealant immediately after use with a damp cloth or appropriate solvent (refer to product packaging for specific recommendations if available). Once cured, sealant can be difficult to remove.
  • Maintenance: The cured sealant can be cleaned with mild household detergents. Avoid abrasive cleaners or solvents that could damage the surface or the sealant.
  • Re-application: If the sealant becomes damaged or degraded over time, it should be removed and re-applied following the setup instructions.
