Sopro Sanitary Silicone is a ready-to-use, acetic-curing silicone sealant with fungistatic properties for elastic filling of perimeter and movement joints in sanitary areas, e.g. between tiling and bathtub, shower tray, washbasin, sink, cooking modules and kitchen worktops (use Sopro Marble Silicone for marble/natural stone) in food-processing facilities, WC pans and urinals. For grouting around door and window frames, at vertical angles and perimeter joints between wall finishes and flooring indoors, and for underwater applications (with Sopro Primer UW 025 for silicone sealants).
