FAQs
How long does it take for the sealant to cure?
The tack-free time is approximately 15-30 minutes, and a full cure typically takes 24-48 hours, depending on bead size, temperature, and humidity.
Can this sealant be painted over?
No, silicone sealants are generally not designed to be painted over. It is best to choose a colour that matches your project or to use a paintable sealant if painting is required.
Is the Hippo Prestige 4in1 Silicone suitable for exterior use?
Yes, it is weather and UV resistant, making it suitable for exterior applications where a flexible, durable seal is needed, but not for joints subject to significant movement or structural loads.
What is the shelf life of the sealant?
Unopened cartridges typically have a shelf life of 12-18 months when stored in a cool, dry place. Check the packaging for specific expiry dates.
Can I use this sealant around a hot water tank or radiator?
The sealant is heat resistant to a degree, but for very high temperatures or direct contact with heating elements, a high-temperature sealant may be more appropriate. Consult product specifications for exact temperature limits.
Is it safe to use in food preparation areas?
Yes, the sealant is FDA Approved (21 CFR 177.2600), making it food safe for use in kitchens and food contact applications once fully cured.
Troubleshooting
Sealant is not sticking to the surface
Ensure the surface is completely clean, dry, and free from dust, grease, or moisture. Re-apply sealant after proper surface preparation.
Sealant is uneven or stringy during application
Check the sealant gun for proper function. Ensure the cartridge is at room temperature. Try applying at a consistent speed and pressure.
Mould is still appearing after application
While mould-resistant, extremely prolonged or severe damp conditions may eventually allow surface growth. Ensure adequate ventilation. Clean the affected area with a mild detergent and water.
Sealant has not fully cured
Curing time depends on temperature and humidity. Ensure a minimum of 24-48 hours in normal conditions. Avoid disturbance during curing. Check product expiry date.
