Semi-Rigid Epoxy Joint Sealant & Crack Filler
SLABFLEX® 300 is a two-component, 100% solids, semi-rigid epoxy joint sealant and crack filler engineered to protect concrete joint edges and minimize deterioration caused by impact, traffic, and chemical exposure. It combines excellent adhesion with high elongation, delivering durability and flexibility not typically found in general-purpose epoxy materials.
Designed for demanding industrial and commercial environments, SLABFLEX® 300 reinforces concrete joints and cracks subjected to heavy foot traffic, forklift traffic, and chemical attack, including food acids.
SLABFLEX® 300 is available in multiple viscosities to accommodate a wide range of installation needs, including liquid, thixotropic, and paste grades.
SLABFLEX® 300 is mixed at a 2:1 ratio by volume and installed into properly prepared concrete joints or cracks. Coverage varies based on joint width, depth, and installation method. The material is designed to armor joint edges rather than function as a soft elastomeric sealant.
Pot life, cure time, and recoat windows vary depending on temperature and whether standard-cure or fast-cure versions are used. Light traffic is typically permitted within approximately 12 hours under standard conditions.
