FAQs
What surfaces can Hippo Prestige 4 In 1 Silicone Sealant be used on?
It adheres well to most surfaces including ceramics, glass, aluminium, PVC, wood, and natural stone. Always ensure surfaces are clean and dry before application.
Is this sealant suitable for shower trays and bathtubs?
Yes, it is ideal for sealing showers, baths, and washbasins due to its mould-resistant and waterproof properties once cured.
Can I use this sealant for exterior window frames?
Yes, it is weather and UV resistant, making it suitable for top-sealing insulating glass units in exterior window frames (wood, aluminium, PVC).
How long does the sealant take to cure?
The curing time varies depending on bead size and environmental conditions (temperature and humidity). Generally, it skins over within minutes and fully cures within 24-48 hours.
Can I paint over this silicone sealant?
No, silicone sealants are generally not paintable. It is best to use paintable sealants if painting is required, or to mask the area before applying the silicone and then remove the masking tape once tooled.
What does 'low modulus' mean in relation to this sealant?
'Low modulus' means the sealant is highly flexible and can stretch significantly (up to 20% in this case) without breaking, making it ideal for joints that experience movement.
Is this product safe to use in kitchens around food preparation areas?
Yes, the Hippo Prestige 4 In 1 Silicone Sealant is FDA Approved (21 CFR 177.2600), making it safe for use in areas where food contact may occur, such as around kitchen sinks and countertops.
What is the shelf life of the product?
Unopened cartridges typically have a shelf life of 12-18 months when stored in a cool, dry place away from direct sunlight. Refer to the packaging for the exact expiry date.
Troubleshooting
Sealant not dispensing
Ensure the cartridge is correctly loaded into the sealant gun and the trigger is fully depressed. Check that the nozzle has been properly cut and the inner seal punctured.
Poor adhesion to surface
The surface may not have been properly prepared. Ensure it is clean, dry, and free from dust, grease, or previous sealant residue. For porous surfaces, pre-treatment might be necessary; consult product literature.
Uneven sealant bead
Maintain a consistent speed and pressure while applying the sealant with the gun. Practice on a scrap piece of material. Ensure the nozzle is cut at a uniform angle.
Sealant skinning too quickly
Work in smaller sections if necessary, especially in warm or dry conditions. Tool the sealant immediately after application to ensure a smooth, unbroken finish.
Mould reappearing after sealing
While the sealant is mould resistant, persistent high humidity or poor ventilation can still encourage surface mould growth on adjacent areas. Ensure adequate ventilation and clean the surrounding area regularly.
