I'm preparing a design for a column baseplate (1/2" thick ASTM A572 Grade 50), and need to determine whether there is any great risk of corrosion due to water seeping between the base plate and the grout bed upon which it will rest. Other columns which were installed in crude fashion exhibit significant rust, which we'd like to avoid, this time around.
Should the bottom of the plate be painted, and if so, with primer only, or primer + finish coat? (Primer is alkyd, topcoat is alkyd enamel.)
The facility is, for all intents and purposes outdoors (and it may be exposed to road salt, snow and water).
