Product details

The special hotel and spa silicone OTTOSEAL® S 140 is a sealant that was explicitly developed for expansion and connection joints in permanently moist hygiene or swimming pool areas. OTTOSEAL® S 140's greatest strength is its double protection against mould: In addition to the fungicidal finish to protect against mould infestation, the special silicone is also equipped with the environmentally safe OTTO Fungitect® silver technology. This ensures durable joints even in particularly stressed areas of hotels and spa facilities. In addition, OTTOSEAL® S 140 is compatible with natural stone and does not causes any marginal staining.
