AMPP TR21540-2022, Correlating Qualitative Surface Profile Assessment Methods to Quantitative Methodology on Prepared Concrete Substrates

Product Number: AMPP TR21540-2022

Publication Date: 2022

Coating/lining manufacturers and/or facility owners frequently specify cleaning and roughening of the concrete surface prior to product installation. The specifications may reference qualitative methods including visual assessments using comparison coupons or quantitative methods including surface profile depth measurements. However, prior to this Technical Report, there was no known data to inform a conversion between qualitative and quantitative methods. The outcomes of this Technical Report enable coating manufacturers, engineers, specifiers, and contractors to convert well-established qualitative methods to quantitative values based on an interlaboratory experiment. While current quantitative methods can measure up to 6 mm (250 mils), extremely rough concrete surfaces (exceeding ~1.5 mm, or ~50 mils) were not included in the experiment due to the inability to stabilize the instrument probe and obtain accurate data.
