The odourless silicone for stone and tiles

Whether for a hotel’s spa centre or your bathroom at home, 445 Stein + Sanitär provides reliable joints on natural stone and tiles. The natural stone-compatible alkoxy-based silicone stands out for its excellent hold. Due to the fungicides and bactericides it contains, it is highly effective in inhibiting mould growth. The sealant does not contain any plasticisers, which means that it does not cause edges to stain. In addition, 445 Stein + Sanitär is odourless and compatible with commercially available cleaning agents and disinfectants. As well as being suitable for sealing work in sanitary areas like bathrooms, it is also suitable for use in kitchens and clean rooms.
