W. CONSHOHOCKEN, PA – 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.
ASTM D 7682, Test Method for Replication and Measurement of Concrete Surface Profiles Using Replica Putty, was developed by Subcommittee D01.46 on Industrial Protective Coatings, part of ASTM International Committee D01 on Paint and Related Coatings, Materials and Applications.
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. Owners can retain replicas should a failure occur. Contractors can retain replicas for verification of adherence to the specification’s required anchor profile ranges. Coatings 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.
