Application Details

Surface Preparation

  • Surfaces must be clean, sound, dry or damp (no standing water)
  • Remove grease, curing compounds, and other contaminants
  • Install backer rod or bond breaker to control depth and prevent 3-point bonding
  • For green concrete: Wait 24 hrs after pour, control joints cut at least 8 hrs prior
  • For damp concrete: Wait 1 hour after water is removed
  • Primer is required for immersion service

Joint Design

  • Recommended ratio: 2:1 width to depth
  • Depth range: ¼" to ½"
  • Min. depth for traffic areas: ½"
  • Max. movement: ±25% of joint width

Application Conditions

  • Ambient/Substrate Temp: 40°F to 100°F
  • Precondition cartridges to ~70°F for best flow
  • Pour in one direction, allow sealant to level naturally
  • Tooling is minimal but can be used for finishing
