FAQs
What surfaces can this sealant be used on?
It adheres strongly to a wide variety of common building materials, including wood, concrete, brick, masonry, metal, and certain types of plastics.
Is this sealant suitable for outdoor use?
Yes, it features a waterproof and weatherproof formula making it suitable for both interior and exterior applications.
How long does it take for the sealant to cure?
Curing time can vary depending on bead size, temperature, and humidity. Typically, it begins to skin over within minutes and can be tack-free within an hour, with full cure taking longer.
Can I paint over this sealant?
Once fully cured, the sealant can generally be painted over. It is advisable to test on a small, inconspicuous area first to ensure compatibility with your chosen paint.
What is the shelf life of an unopened tube?
Unopened tubes should be stored in a cool, dry place and typically have a shelf life of around 12-18 months. Always check the packaging for specific expiry dates.
Does it require a special applicator?
The 290ml tube is designed to be used with a standard caulk gun for easy and controlled application.
How should I clean up uncured sealant?
Uncured sealant can be wiped away with a damp cloth or cleaned using an appropriate solvent. Cured sealant will need to be removed mechanically.
Troubleshooting
Sealant not dispensing
Ensure the inner seal of the tube is punctured and the caulk gun is properly engaged. Check that the nozzle is not blocked.
Poor adhesion
Verify that surfaces were clean, dry, and free from dust, grease, or contaminants before application. Ensure the material is compatible.
Uneven bead application
Adjust the pressure on the caulk gun and practice on a scrap surface. Ensure the nozzle is cut to the appropriate size for the gap.
Sealant remains tacky after application
This may indicate insufficient ventilation, very high humidity, or application in temperatures outside the recommended range. Ensure proper curing conditions.
