If you want to paint metal fences, you will be in for a lot of work. This type of fence is prone to holding excess water, attracting grime and rusting. It is possible to paint metal fences to make them look new.
Step 1 - Removing Rust from the Metal Fence
When you set out to paint metal, you need to make sure that it is ready to accept the primer and metal paint. Metal, especially outdoors, is subjected to many elements that can damage it. You will find that it will become rusty, retain water and attract oil or grime. The first thing you need to do is inspect the metal fence for rust. If rust is present, put on your work gloves, glasses and mask; grab a brush or steel wool and get to work. Vigorously scrub the area of rust to remove the loose particles. This will be hard work and take time to finish. Dampen a rag with mineral spirits and begin removing the remaining rust. Replace the rag whenever it becomes too dirty. You will not be able to remove all of the rust.
Step 2 - Washing the Metal Fence
Mineral spirits can inhibit certain metal paint, so it's always a good idea to wash the fence prior to applying primer or paint to it. Fill a bucket with hot water and soap. Soak a rag and wash the metal fence. Rinse the soap off with a hose and then dry the fence with a rag or allow it dry overnight.
Step 3 - Paint Metal Fence
You will first start with the primer metal paint. The primer gives the top coat of paint something to adhere to. If the primer is too thick to properly apply, add a small amount of mineral spirits to it. Add very small amounts, stirring after each addition and only adding more if it's still too thick. Dip your brush into the primer and begin applying the primer metal paint to the metal fence. Work quickly, using even strokes to prevent primer from pooling anywhere on the metal fence. Pay special attention to streaks, bubbles and any other imperfections. In tight areas, use the paintbrush to dab the metal fence with the primer.
After the primer metal paint has had a chance to dry (this can take at least one day) you can paint the metal fence with the top coat of paint. Choose a clean brush and apply the paint to the metal fence. Apply the top coat the same way as you applied the primer. Look out for missed spots, streaking and pooling paint. Dab the hard to reach areas. Wait for the paint to dry and apply a second coat.
