Filling Control Joints With a Semi-Rigid Epoxy Filler
Scope of Work: Cleaning and filling control joints in concrete slabs on grade to prevent edge deterioration.
Concrete slab edge deterioration due to lack of semi-rigid joint filler in control joints.
- Clean joint sidewalls with wet or dry cut saw (dry cut is preferred) with proper dust collection.
- Saw cut to a minimum of 1”.
- Clean and remove all dust, water and slurry from the joint.
- If wet cut, allow joint to dry before installation of epoxy.
- Make sure all side walls are clean and dust free.
- Once clean and dry, fill with semi-rigid epoxy (Joint Shield 5000 Epoxy 80A or Joint shield 5100 Caulk Grade), slightly overfilling the joint. Oven-dried sand (Prime Blend) may be used to control seepage.
- Never use backer rod.
- Allow material to harden and remove excess material with razor blade or grinder flush with the surrounding floor surface.
- Observe OSHA (or comparable) personal safety guidelines.
- Carefully read SDS prior to handling any chemical.
- Always wear safety goggles when drilling, grinding, flushing, injecting or handling resins.
- Always wear protective clothing, chemical resistant gloves and safety goggles at all times when handling resins.
- Make sure no loose clothing can come into contact with moving mechanical equipment.
- Keep first aid kit (eyewash, bandages, etc.) present on site with easy access.
- Epoxy-based joint filler: Joint Shield 5000 Epoxy 80A or Joint Shield 5100 (Caulk Grade) – bulk or in Quick Mix cartridges
- Prime Eco Flush (pump cleaner)
- Concrete saw with diamond blades and dust collection
- FlowMaster pump or the Patriot pump or a positive displacement two-component pump
- Injection gun if using cartridges (1:1 – 300mL x 300mL)
- Razor and blades to shave or grinder
- Clean empty pails
