Product Information
Full details
The Hippo Prestige 4in1 Silicone is designed for professional contractors and dedicated DIY enthusiasts who require a high-performance sealant for kitchen, bathroom, and glazing applications. Its core strength lies in its low modulus polysiloxane formula, which offers exceptional durability and 20% movement flexibility, ensuring seals remain intact even under thermal expansion. While it is highly versatile and food-safe, users should note that as a low modulus silicone, it requires a clean, dry surface for optimal adhesion, making it less suitable for applications involving standing water during the curing process.

FAQs
Is this silicone safe for food preparation surfaces?
Yes, it is FDA Approved 21 §177.2600, making it safe for use in kitchen environments.
Can I use this on a glass mirror?
Yes, the formulation is compatible with mirrors, but always verify the backing of the mirror is silicone-compatible.
How long does it take to fully cure?
While it skins over quickly, a full cure usually takes 24-48 hours depending on the joint depth and environmental humidity.
Will this silicone grow mould in a shower?
It is formulated with high-performance mould resistance, though regular cleaning is still recommended to maintain its appearance.
Can I paint over this sealant?
No, silicone sealants are generally not paintable; the sealant will reject traditional paint coatings.
Is it suitable for outdoor use?
Yes, the weather-resistant properties make it suitable for exterior glazing and sealing applications.
Troubleshooting
Sealant is not adhering to the surface
Ensure the surface is completely free of soap residue, moisture, or oils; re-clean with a solvent and allow to dry fully.
Bubbles appearing in the sealant bead
Apply the sealant in a steady, slow motion to prevent air entrapment in the nozzle.
Sealant is difficult to smooth
Use a light mist of soapy water on the tooling surface, but ensure it does not enter the joint gap before it cures.
Pros and Cons
Pros
- Certified food-safe for kitchen environments
- Excellent elasticity prevents long-term joint failure
- High resistance to mould and mildew growth
- Compatible with delicate natural stone surfaces
- Consistent, easy-to-control application
Cons
- Requires completely dry surfaces for initial bond
- Not suitable for continuous underwater submersion
- Longer cure time compared to high-modulus acetoxy silicones
- Specific brown colour may not match all decor palettes
Setup, Compatibility & Care
To ensure optimal performance, remove all dust, grease, and old sealant from the substrate before application. Surfaces must be clean, dry, and structurally sound. Insert the 300ml cartridge into a standard caulking gun, cut the nozzle to the desired bead size, and apply in a continuous motion. Use a smoothing tool or a gloved finger dipped in a mild soapy solution to profile the bead. For care, avoid using abrasive chemical cleaners directly on the cured silicone, as these can degrade the material over time. Regular cleaning with mild, non-acidic soap and water is sufficient to maintain the integrity and appearance of the seal.
