Colored metal roofing – Galvanized metal is a metal which is treated with hot zinc which is designed to protect the roof from the elements. Often these ceilings are painted with a certain type of paint for use on galvanized sheet. Once the paint begins to peel off, and must be painted, you can use the appropriate primer and acrylic topcoat manufactured by Sherwin Williams.
Before you can paint the ceiling, you need to get it ready to be painted. Inspect the roof and observe the condition of the paint on the ceiling. If the paint is in poor condition and peeling. The roof must be free of any old paint before you paint it. When the roof is clean, let it dry before applying the primer.
Colored metal roofing, apply a coat of Sherwin Williams galvanized metal primer with either a spray gun, roller or brush. Make sure the primer is applied in even strokes. Let the primer dry thoroughly before applying the top coat. The amount of heat and moisture in the air will affect how long it takes for the primer to dry. Identify how you will paint the ceiling. Start the morning if possible, and start on the side of the roof that is still in the shade.
