b.
Strippability: On cementitious substrate surfaces, after asphalt
used in the foaming test application has cooled to ambient
temperatures, test coating for adherence.
Should a portion of
the sample be readily stripped clean from the surface, do not
consider the surface to be dry and do not start application.
Should rain occur during application, stop work and do not resume
until surface has been tested by the method above and found dry.
