How to Paint Galvanized Metal

Galvanized metal is metal that's been dipped in hot zinc to protect it from the weather. Unfortunately, paint doesn't always adhere so well to zinc.

Difficulty: Moderately Easy

Instructions

Things You'll Need:

• Galvanized Metal Primer
• Paints
• Mineral Spirits
• Mineral Spirits
• Newspaper
• Newspaper
• Paint Sprayers
• Wet And Dry Sandpaper

1. 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.

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

3. Allow the metal to dry.

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

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

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

on 5/20/2008 I wouldn't use mineral spirits. It will chemically react with the zinc to a create a soapy film and peel later. No oil/alkyd paint/solvents should be used. New metal will have an oil layer on it while old will have an oxidized layer on it. Both need to be removed.
