ARDEX ST is a neutral cure elastic silicone sealant that minimises the risk of discolouration in porous materials, making it suitable for use with most finishes including moisture-sensitive natural stones. After curing, ARDEX ST is resistant to commonly used cleaners, disinfectants and UV exposure, and its antifungal properties inhibit the growth of fungi and moulds.
It is easy to apply and smooth and, due to its high elasticity, it can accommodate movement of up to 20% of the applied width. It is available in Transparent and 13 colours designed to match the most popular ARDEX-FLEX Flexible Tile Grout colours.
NOTE: Does not contain acetic acid.
