Coating Failure Analysis Learning Series – Part 5 – Field Microscopic Examination

Welcome to the KTA Coating Failure Analysis Video Learning Series!

This is a six-part video series that demonstrates the field and laboratory methods that were used to determine why a new coating system applied to a previously painted concrete floor had failed. Each part is standalone, addressing a different aspect of the evaluation, but when viewed in order, they present a systematic step-by-step process for analyzing the cause of the failure, starting with the initial collection of background information, and ending with the laboratory analysis of samples.  The first five videos, covering the field assessment, were filmed at an actual jobsite and are narrated by KTA President, Ken Trimber. The sixth video covering the Laboratory Forensic Analysis was filmed in the KTA laboratory and is narrated by KTA Senior Chemist, Chrissy Stewart.

The fifth video in this series is embedded below.  There will be one last installment next Friday, October 7th, so be sure to check back then. We will also be sending out an email reminder containing the last part to those who are on our contact list.  If you’re not on our list, and would like to receive the email reminders, please CLICK HERE to opt-in to our contact list.

We hope these videos are of value to you. If you find them to be helpful, you can share them with colleagues on a variety of social media platforms using the Social Share Bar on the right-hand side of this screen (bottom of screen if using Mobile Device). Without further ado, here is the 5th video in the series.

Part 5 – Field Microscopic Examination

The results of the field microscopic analysis of failing areas is discussed.  Techniques for removing representative samples of both failing and non-failing areas is demonstrated, including written and photographic documentation of the sample areas.
