How to Paint Galvanized Metal

Lay down a thick layer of newspaper below the area to be painted. If you're working over grass, you'll want to protect your lawn from chemicals that might kill it.

Use fine wet/dry sandpaper dipped in mineral spirits and lightly sand the entire surface that is to be painted.

Allow the metal to dry.

Apply a primer designed specifically for galvanized surfaces. Check the manufacturer's recommendations - some suggest two coats with a sanding session in between.

Be sure to choose a paint that will hold up to the weather (see Related eHows).

Apply the paint with a sprayer for the most uniform coverage.
