Basic Use: Jointfill 302 is a two-component epoxy joint filler designed to be used in control and construction joints in concrete industrial floors. Jointfill 302 is a low modulus, flexible joint filler used in saw cut floor joints to provide support and load-bearing capacity at the joint edges. Jointfill 302 is used in floor control joints where slight movement is possible due to thermal variations. It is available in two consistencies, self-leveling and gel, for horizontal and vertical applications.
Typical Applications: Control and construction joints in industrial concrete floors; repair compound to seal and fill random cracking in floors; joints in penitentiaries where a tamper-proof and gouge-resistant sealant is required.
Limitations: Do not use outside or as an expansion/ contraction sealant. New concrete slabs must be at least 3 months old before installing Jointfill 302, according to ACI 302.
Composition: Jointfill 302 is a two-component, moisture insensitive, 100% solids epoxy joint filler and sealant.
Applicable Standards: ACI 302, Guide for Concrete Floor and Slab Construction, Section 4.10, Joint Materials.
