Sopro Marble Silicone
Sopro Marble Silicone is a neutral-curing silicone sealant for elastic filling of perimeter and movement joints in marble and other natural stone finishes, ceramic and cast stone coverings, and for grouting window sills. Also suitable for low-stress grouting of all joints in outdoor coverings with large-format units, and for cooking modules and kitchen worktops (marble/natural stone) in food-processing facilities.
Sopro Marble Silicone is a ready-to-use, sprayable, neutral-curing, oxime-free silicone sealant with fungistatic properties, which is subject to continuous quality monitoring. After curing, silicone sealant is elastic and resistant to weathering, ageing and UV radiation. It does not react with fresh cement.
