Product information and data sheets

Perfect joints stone after stone – indoors, outdoors, even underwater

Natural stones such as granite, quartz and marble create a special atmosphere wherever they are used. When sealing these materials, however, it is important to pay attention to their sensitive surfaces. We have developed a special sealant for this purpose: 440 Naturstein. Unlike conventional silicones, this material does not contain any migratory ingredients. This means that there will not be any staining around the edges, nor will there be any signs of corrosion when the sealant comes into contact with metals. Due to its fungicidal and bactericidal ingredients, 440 Naturstein is not only ideal for sanitary spaces, but also for joints exposed to heavy stress and in spa and wellness facilities. With the exception of the matt and structured colors, the material is ideal for use underwater in salt and chlorine water pools. Due to its excellent mechanical properties, it can also be used in kitchens. And that’s not all – a wide range of colours also leaves ample scope for individuality.
