This method covers test methods and selection criteria for prequalification of sealers for protecting new concrete or prolonging the life of sound in-service concrete used in highway structures. Sealer testing and evaluation for routine and job site product quality assurance, field performance, and re-application are provided in the ??Guideline for Quality Assurance, Job Site Quality Control, and Reapplication of Protective Sealers for Portland Cement Concrete.??
Sealers are divided into two basic types: coatings, which remain on the surface; and penetrants, which penetrate into the concrete to some measurable depth and do not substantially change the appearance of the concrete.
