Concrete Surface Profiles
The texture — often called the profile — of concrete is one of the most important characteristics for a coating or overlayment bonding. A new ASTM International standard now fills the need within the concrete surface preparation field for a means of measuring and permanently replicating the profile of a concrete coated building surface.
D7682, 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.
“This technique uses replica putty to make impressions of concrete surfaces for either visual comparison or for quantifying the surface roughness,” says David Beamish, general manager, DeFelsko Corp., and a D01 member.
The new standard will be useful to several different parties:
