Frequently Asked Questions
What joints is Sikaflex-1c SL used on?
Horizontal expansion joints in concrete and cementitious slabs such as sidewalks, plazas, pavements, balconies, warehouses, and civil structures. Canal and water-treatment joints work when primed for immersion.
What movement capability does Sikaflex-1c SL provide?
Published movement capability is +/-25% under ASTM C719. Maximum expansion and contraction should not exceed 25% of average joint width.
What green-concrete wait does Sikaflex-1c SL need?
It can be placed after the concrete has cured a minimum of 24 hours at 75 F. Control joints need to be cut open at least 8 hours before sealant goes in.
What tack-free time does Sikaflex-1c SL have at 73 F?
Tack-free time is 1 to 2 hours at 73 F and 50% RH. Final cure is 3 to 5 days.
What joint orientation suits Sikaflex-1c SL?
Self-leveling consistency is for horizontal joints. Vertical or overhead work needs a non-sag grade.
