Application Overview
SLABFLEX® 400 is typically applied by hand using a trowel or putty knife. Coverage will vary depending on crack width, depth, surface texture, and application thickness. Additional epoxy systems may generally be applied once the material has hardened.
Light foot traffic is typically permitted after approximately 12 hours, with normal traffic in about 24 hours under standard conditions (70°F and 50% relative humidity). Cure times may vary based on temperature and site conditions.
