8 ASSESSING THE RESULTS (continued)
8.2 EXAMINING THE DOLLY (COATINGS ON CONCRETE)
When testing coatings on concrete it is common for the adhesive bond
between the coating and the concrete to exceed the strength of the
concrete itself. In this case concrete will be removed from the surface
and will be seen on the coating on the dolly face.
Observing the test area will give additional information about the type of
failure; adhesion and cohesion between different layers of the coating.
