Question posted - April 6 to April 12, 2015:

When applying a 100% solids, fast-curing polyurea coating on concrete, what is the best method for verifying that the proper thickness has been applied?


Selected Answers

From HECTOR MEDINA of PEQUIVEN on April 10, 2015:
Ultrasonic testing should be used to verify thickness.

From Larry Muzia of Exceletech LLC on April 9, 2015:
I believe in a two-fold approach, using both ultrasonic equipment designed to be used with a polyurea in conjunction with proper calibration methods, and, as a cross-check, determining the quantities used versus the area to be coated. I have seen unsatisfactory work done by more than one contractor because of a lack of the correct methodology to insure a proper application,  including intentionally reducing material cost.
