Moisture Testing and Moisture Surveys: Assessing Concrete Floors for Coating Readiness

From JPCL, August 2016

By Brian O’Farrell, DP Coatings Ltd.

There are many ways moisture can affect concrete floor coatings but moisture testing alone is not sufficient to detect all potential problems. Sometimes problems are not apparent or may not even exist until coatings have been applied. Performing a moisture survey — an inspection of a building and its environment prior to performing any tests — will provide a clearer picture of the potential problems moisture in both liquid and vapor form can pose....
