Glue failures typically occur when the glue is improperly mixed or
the coated surface has not been adequately prepared (pg. 4).
The PosiTest AT-A provides an interface to document the nature
of the fracture for each pull-off test (pg. 7). Fracture results are
included in test reports.
Glue failure: visible separation of the glue from itself,
the coating, or dolly (no coating visible on the dolly face).
