Sikalastic M 262 is a one‑component polyurethane liquid membrane used for waterproofing wet rooms and other non‑exposed applications. It forms a highly elastic, hydrophobic coating that resists water penetration under pressure and can be applied at ambient temperatures between +5 °C and +35 °C. The cured film has a Shore A hardness of about 50, tensile strength around 1.5 N/mm² and elongation of roughly 700 %.
