Product Information
Full details
The HIPPO Prestige 4-in-1 Silicone Sealant is an ideal solution for professional contractors and DIY enthusiasts who need a reliable, high-performance bond for demanding kitchen and bathroom environments. Its standout feature is its advanced low-modulus polysiloxane formula, which provides 20% permanent elasticity to accommodate natural thermal expansion and building movement without cracking. While it offers exceptional versatility and food-safe properties, users should note that as a silicone-based product, it requires a completely clean, dry, and grease-free surface to ensure optimal adhesion and long-term durability.

Pros and Cons
Pros
- Excellent movement accommodation due to low-modulus formula
- Suitable for food preparation areas

Setup, Compatibility & Care
To achieve the best results, ensure all surfaces are clean, dry, and free of dust, grease, or old silicone residues before application. Cut the nozzle at a 45-degree angle to match the desired bead width and use a standard caulking gun to apply a consistent bead. Tool the sealant within minutes of application using a smoothing tool or soapy water to achieve a neat profile. Once applied, allow sufficient time for the sealant to cure fully before exposing the area to water or heavy mechanical stress. For care, avoid using abrasive chemical cleaners on the cured silicone, as these can degrade the mould-resistant properties over time.
