Professional Silicone Kit
Achieve professional-quality silicone joints from start to finish with the Walther Strong Professional Silicone Kit.
Combining our premium Rilicone silicone sealant, specialist Smoothing Spray, and versatile Joint Spatulas, this complete system has been designed to help you create clean, durable, and visually flawless silicone joints with ease.
At the heart of the kit is Rilicone, a high-performance, neutral cure silicone sealant that delivers excellent adhesion to most common building materials without the need for primer. Suitable for kitchens, bathrooms, glazing, façades, natural stone, and general construction applications, it provides a permanently flexible seal that resists cracking, shrinking, UV exposure, ageing, moisture, and mould growth.
To help achieve the perfect finish, the kit includes Walther Strong Smoothing Spray. Unlike washing-up liquid or soapy water alternatives, this specially formulated, solvent-free solution allows silicone to be tooled smoothly without compromising adhesion or anti-fungal performance. It helps create crisp edges, reduces drag and smearing, and supports a cleaner finishing process.
The included 4-piece Joint Spatula Set features 14 profile edges, enabling consistent, professional tooling across a wide range of joint sizes and applications. By eliminating the need for finger tooling, the spatulas help prevent contamination while preserving the silicone’s anti-fungal properties and ensuring a longer-lasting finish.
Suitable for both professional tradespeople and DIY users, the Rilicone Professional Silicone Finishing Kit provides everything needed to achieve clean, watertight, and professional-looking joints every time.
