For coatings with a high-solids content (95 percent or more), what kinds of defects, such as holidays or micropores, are possible or likely to occur in the applied film? How can these be prevented or remedied?


Selected Answers

From Jerry Trevino of Protective Liner Systems on March 7, 2017:
Concrete outgassing creates holidays; minimize outgassing and it will reduce holidays and pinholes.

From Joseph Travers of C&JTRAVERS Industrial Painting on March 5, 2017:
I would be interested in the long answer, Dennis. Why would this defect occur with solvent-free, brush-applied coatings?

From Dennis Harris of International Paint on March 2, 2017:
Short answer, pinholes are generally problematic with high solids coatings. I've found that applying a mist coat and cross-spray application usually cuts the pinholes down tremendously.
