Description

Non-sag concrete repair mortar with integral corrosion inhibitor for vertical and overhead applications. It is a trowel-grade, lightweight, polymer-modified, silica fume-enhanced repair mortar.
  • Non-sag consistency for 2 inch thick lifts
  • Integral corrosion inhibitor
  • Low chloride permeability
  • Low shrinkage
  • Polymer-modified for adhesion and freeze-thaw stability

Features

  • Non-sag consistency able to be placed in 2 inch (51 mm) thick lifts
  • Readily sculpted, shaved, and finished to match existing substrate
  • Very low chloride permeability and integral corrosion inhibitor protect reinforcing steel
  • Only requires addition of potable water
  • Lightweight microscopic beads improve vertical and overhead workability
