Ardex ST Silicone is a one component, neutral cure silicone sealant which can be easily applied and smoothed. Ardex ST Silicone minimises discoloration, and is also suitable for filling joints between natural stone tiles such as marble and granite.

Due to its high elasticity, Ardex ST Silicone can accomodate movement up to 20% of the applied width. After curing Ardex ST Silicone is resistant to commonly used cleaners, disinfectants, and UV exposure. Joints can be cleaned easily, and the inclusion of fungicide prevents growth of fungus and moulds, preserving the joint surface from deterioration.
