Product Overview
JOINT-GUARD™ CJ is a two-component, 100% solids flexible epoxy joint filler designed for the repair and protection of concrete control joints and saw-cut joints in industrial and commercial floor systems. Engineered for on-grade concrete slabs, this heavy-duty epoxy filler provides strong adhesion, watertight sealing, and flexible movement capability for joints exposed to continuous traffic and operational stress.
Formulated to achieve up to 100% elongation, JOINT-GUARD™ CJ maintains joint integrity under slab movement, vibration, and impact while resisting deterioration caused by steel wheel traffic, forklifts, and material handling equipment. The 100% solids epoxy formulation delivers durable performance without shrinkage, helping extend the service life of concrete floors in demanding facility environments.
Features and Benefits
- Flexible epoxy joint filler for concrete control joints and saw-cut joints
- Up to 100% elongation to accommodate slab movement and vibration
- High bond strength for durable joint repair and protection
- Watertight sealing to help prevent moisture intrusion and contamination
- Resistant to heavy traffic, forklift loads, and steel wheel impact
- 100% solids formulation for long-term durability and low shrinkage
- Suitable for interior and exterior concrete slab applications
Typical Applications and Users
JOINT-GUARD™ CJ is commonly used in industrial, commercial, and municipal facilities where concrete floor joints are exposed to heavy traffic, impact loading, and operational movement.
Typical applications include:
- Saw-cut and control joint filling in concrete floors
- Repair of damaged joints and moving cracks
- Protection of expansion and contraction joints in industrial slabs
- Concrete floor maintenance in high-traffic operational areas
- Joint stabilization in facilities using steel wheel equipment
Common environments include:
- Manufacturing plants
- Warehouses and distribution centers
- Loading docks
- Transit and utility facilities
- Processing and production areas
- Commercial and institutional concrete floors
The product is used by facility maintenance departments, plant engineering teams, concrete repair contractors, and industrial flooring professionals responsible for maintaining operational concrete surfaces.
Used by Facility Maintenance and In-House Teams
JOINT-GUARD™ CJ is frequently specified by facility managers and in-house maintenance teams seeking to protect concrete floor joints while minimizing operational disruption and long-term repair costs.
Its flexible epoxy formulation helps reduce joint edge deterioration caused by repeated traffic and slab movement, making it suitable for preventative maintenance programs and ongoing floor rehabilitation projects. The watertight bond also helps protect concrete substrates from moisture infiltration and contamination in active industrial environments.
The product is commonly used in facilities operating forklifts, pallet jacks, carts, and steel wheel equipment where joint failure can create safety concerns, surface damage, or maintenance interruptions.
Used by Contractors and Professional Applicators
Concrete repair contractors and industrial flooring applicators use JOINT-GUARD™ CJ for control joint repair, joint stabilization, and concrete floor restoration projects in demanding commercial and industrial environments.
The 100% solids epoxy system supports durable, high-strength repairs in areas exposed to repetitive traffic, impact loading, and operational vibration. Its flexibility and elongation characteristics help maintain joint performance in slabs subject to thermal movement and dynamic loading conditions.
JOINT-GUARD™ CJ can be incorporated into broader concrete rehabilitation, floor protection, and industrial maintenance programs where long-term joint durability is required.
Product Summary
JOINT-GUARD™ CJ is a flexible, two-component 100% solids epoxy joint filler used to repair and protect concrete control joints and saw-cut joints in industrial and commercial floor systems. It provides strong adhesion, watertight sealing, and up to 100% elongation to accommodate slab movement and heavy traffic conditions.
Commonly used in warehouses, manufacturing plants, loading docks, and high-traffic industrial facilities, JOINT-GUARD™ CJ helps extend the service life of concrete floors exposed to forklifts, steel wheel traffic, vibration, and operational wear.
