Patterned cracking in the paint film resembling the scales of an alligator.
Blistering
Bubbles caused from a loss of adhesion and lifting of the paint film from the underlying surface.
Adhesion (Blocking)
Undesirable adhesion between two painted surfaces or between paint and weather stripping.
Caulk Failure
Loss of caulk's initial adhesion and flexibility causing painted caulk to crack and/or pull away.
Peeling - Due to Moisture (Inside)
Loss of adhesion of the interior paint caused by high levels of moisture.
Peeling - Due to Moisture (Outside)
Loss of adhesion of exterior paint, usually exposing the bare surface.

Emulsion Paint Crazing
