Summarizes the capabilities, operating requirements, and limitations of the various methods used to prepare concrete surfaces for the application of protective sealers, coatings, polymer overlays, and concrete repair. Benchmark profiles are included which provide visual standards for purposes of specification, application, and verification. In this updated version of the guideline you will find; surface retarders and handheld breakers have been added to the surface preparation methods; surface preparation methods have been updated; and a new appendix summarizes considerations for selecting surface preparation methods and describes various test methods used to evaluate the prepared surface. Plus, concrete surface profile (CSP) 10 has been added to reflect a more aggressive CSP used for concrete repair.

La preparación correcta de la superficie es un elemento clave para determinar el éxito de un proyecto de restaura-ción de concreto. La preparación inadecuada de la super-ficie puede llevar a la falla del sistema de protección o material de reparación, que resulta en mayores repara-ciones, gastos agregados y pérdida de uso, y puede en último término comprometer la integridad de la estructura. La preparación de la superficie es el proceso por el cual una superficie sana, limpia y adecuadamente raspada se produce sobre un sustrato de concreto. La preparación de la superficie incluye la remoción de lechada, suciedad, aceite, capas, pintura, recubrimientos, concreto sano o en mal estado y otros materiales que interferirán con la ad hesión o penetración de un sellador, recubrimiento, revestimiento de polímeros o material de reparación.

Illustrates and describes the application methods commonly used for placement of concrete repair materials, along with material requirements, the best applications, and cautions and limitations for each. In addition, engineering considerations, surface preparation, constructability, environmental factors, quality assurance/control, and safety are addressed.

A tool to help designers, specifiers, contractors, and manufacturers make the best possible decisions in selecting materials for the repair of concrete surfaces. It fully describes a process used to develop sound selection criteria that will ensure that, for each project, the material properties needed to produce durable repairs are specified.
