How to Paint Aluminum Flashing

Few things inspire your average do-it-yourselfer more than the thought of remodeling the exterior of his or her home with a brand new coat of paint. Most experienced painters know the basics of applying paint to wood. However, when it comes to painting metallic surfaces like aluminum flashing, there are a few preparation techniques you need to know to make sure the finish will hold up over time.

Step 1

Clean dirt, dust and cobwebs from the aluminum flashing using the pressure washer.

Step 2

Use the metal putty knife to remove any peeling or loose paint from the surface of the aluminum flashing. Skip this step if the aluminum flashing is unpainted.

Step 3

Use a wire brush to abrade the surface to promote paint adhesion. Do this by scratching the wire brush against the aluminum flashing in a circular, counter-clockwise motion.

Step 4

Cover all areas you do not want painted with blue painter's tape.

Step 5

Pour latex primer into the painter's pale or 5-gallon bucket. Fill it only about half-way.

Step 6

Apply primer to the aluminum flashing using the 3- to 4-inch paintbrush. Allow the primer to dry for about an hour or two.

Step 7

Repeat steps 5 and 6, except use paint instead of primer.
