The texture - often called the profile - of concrete is one of the most important characteristics of a coating or overlayment bonding. A new ASTM International standard now fulfills the need within the concrete surface preparation field for a means of measuring and permanently replicating the profile of a concrete coated building surface. Coating inspectors can retain profile replicas that can be viewed or measured on-site, prior to coating application, and used as a pass/fail test of whether surface preparations meet specifications. Furthermore coating manufacturers can designate within the product data sheet the range requirements for the coating being used on the project, and engineers can write specifications utilizing the coating manufacturer’s product data sheets that designate a profile range for the required coating.
