When and why would I need to stripe coat if I am using an edge-retention primer?


Selected Answers

From Josh Skinner of The Sherwin-Williams Company on October 3, 2019:
When?  ALWAYS!!! Why?  Even coatings with outstanding edge- retentive properties would have between 50 and 70% edge retention. A stripe coat ensures adequate dry film thickness on edges, outside corners, crevices, bolt heads, welds, and other irregular steel surfaces.

From Per Gabrielsson of Free Lance Consultations and Inspections on October 1, 2019:
Edge retention coating - a nice sales gimmick! It's easy to announce, but who is measuring the dft on edges??? Always stripe coat separately edges and manual welds.
