Some reasons why coatings fail:
  • Concrete surface was not properly prepared and profiled
    • Mechanically grind the surface
    • Shot blast the surface
    • Chemically etch the concrete
  • Relative Humidty too high - surface sweating during application
  • Vapor transmission - moisture passing through the slab is too high
  • Wrong coating selected
    • Match the floor system to the intended use
    • Match the floor system that can handle the vapor transmission level of the slab
