Olympic Galvanized Steel Primer No. 220 is a special formula primer for galvanized steel surfaces. Galvanized Steel Primer No. 220 primer is also used for priming galvanized steel surfaces before applying Super Convoy (but not Super Convoy II). Refer to instructions for application.
Coverage: 200 - 250 square feet per gallon.
Special care must be taken to ensure the success of coating metal pool surfaces. Aluminum, steel, and galvanized steel all have their special properties which require the selection of the appropriate primer. Bare metal should receive two coats of primer to eliminate pinholes and corrosion. DO NOT use the primer over an existing coating.
