Application

Substrate Preparation

Undercut or widen holes and cracks to at least 0.75 inches to allow for material embedment. Remove all loose dirt and aggregate. Ensure surfaces are saturated surface dry (SSD) before application.

Mixing

Combine Pro Plug 45 with clean, potable water to achieve a putty-like consistency. The recommended mixing ratio is 3 parts powder to 1 part water. Mix only small quantities due to the rapid setting time.

Application Method

  • Stopping Water:Start at the top of the crack, applying Pro Plug 45 firmly with a trowel or by hand, maintaining pressure for about 3 minutes to prevent the material from washing out under water pressure.
  • Sealing Cracks and Floor/Wall Junctions:Push Pro Plug 45 into the crack or hole to form a cove at the junction.
  • Anchoring Bolts or Rods:Drill or chisel a hole with at least ½ inch of space around the bolt or rod. Place the bolt, fill around it with Pro Plug 45 using a pointed trowel, and support the bolt until the material sets and is stable.

Application Notes

  • Review complete technical datasheets for detailed application guidelines.
  • Apply immediately after mixing and do not use in moving cracks or as a surface coating.
  • Pre-wet substrate and maintain it moist for at least 15 minutes after application.
