Podcast Breakdown:

0:05 – Introduction of Ken, Doug, and John

0:46 – Scenario: Assume we have a 3-span overpass bridge being fabricated and the owner has two options for painting. One is to apply all 3 coats in the shop (inorganic zinc, epoxy urethane). The other is to apply the zinc in the shop, and the epoxy intermediate and finish in the field. Discussion.

1:27 – Doug gives supporting points behind why all coats should be applied in the shop.

5:39 – John discusses his reasoning for why only the primer should be applied in the shop.

11:39 – Can you adequately control the quality in the field?

12:46 – Does low humidity during coating conditions affect top coating zinc in the shop?

14:25 – Does changing the original scenario from inorganic to organic zinc change John’s opinion?
