Sikalastic-841 ST is a 100% solids, two-component pure polyurea waterproofing and protective coating system. Its rapid gel time of approximately 11 seconds at plus 20 degrees Celsius enables fast turnaround and minimal downtime, which is critical on infrastructure rebuilding works where service interruption must be limited.

The membrane offers excellent crack-bridging, high tensile strength above 15 N per square millimeter and Shore D hardness of 45 to 50, performing reliably on bridge decks, parking structures, industrial floors, and containment tanks.
