Preparation of Concrete for Rapid Coating Application

Session: Good Practice in the Use of High Performance Coatings

Because process shutdowns are expensive, it is desirable to speed up the turn-around time when applying protective coating systems on concrete. Rapid installation of surfacing materials on concrete can be problematic due to inadequate surface preparation, residual moisture, low surface tensile strength, and poor compatibility between the concrete substrate repair materials and the protective coating system. This paper describes rapid hardening and drying concrete mixtures, use of dry surface preparation methods, and application of moisture-mitigating or tolerant surfacing systems to reduce delays required for concrete curing, moisture dissipation, and preparation for coating selection and installation.

Learning Objectives:

  • Understand the factors affecting rapid installation of surfacing materials for concrete.
  • Learn the basics of concrete materials technology regarding maturity for surfacing material application.
  • Know about the alternative methods of concrete surface preparation.
  • Learn moisture-mitigation methods and techniques.
