Get Rid Of All Corrosion Deposits

When you lay out to paint steel, you need to make certain that it prepares to accept the primer and metal paint first. Metal, especially outdoors, is subjected to many elements that can damage it. As mentioned previously, metal fences often become rusty, retain water, and attract oil or grime. So, the first thing you need to do is inspect the surface for rust deposits and clean the ones you might find.

Put on your work gloves, glasses, and mask, grab a wire brush or piece of steel wool, and get to work. Vigorously scrub the rusted area to remove the loose particles. If you find that you’re having trouble, use the wire brush for the bulk of the job and slowly progress down to steel wool to smooth what is left. This will be hard work and take time to finish.

Dampen a rag with mineral spirits once the large deposits are gone and begin removing the remaining rust. Replace the rag whenever it becomes too dirty, and dispose of the rags at a proper facility when you’re finished. It is important to note that you will not be able to remove all of the rust; the idea here is to get the metal surface as smooth and level as possible for painting.

Wash the Surface

Oil, grime, and the mineral spirits you’ve just used can inhibit certain metal paint, so it’s always necessary to wash the fence prior to applying primer and paint to it. Fill a bucket with hot water and soap. Soak a rag or a scrubbing brush and thoroughly scrub all the nooks and crannies of the fence. Rinse the soap off with a hose, and then dry the fence with a rag or allow it to dry overnight.

Paint the Metal Fence

You will first start with a metal primer before you paint to create the most durable, lasting finish possible. The primer gives the top coat something to adhere to. If the primer is too thick to properly apply, add a little bit of the mineral spirits to it. Add it in very small amounts, stirring after each addition and only adding more if it’s still too thick. Dip your brush into the primer when it reaches the desired consistency, and begin applying it along the surface. Work quickly, using even strokes to prevent primer from pooling anywhere.

Pay special attention to streaks, bubbles, and any other imperfections, and in tight areas, use a smaller paintbrush to dab until the entire surface is covered.

After the primer has had a chance to dry – this can take at least one entire day- you can paint the metal fence with the topcoat. Choose a clean brush, dip it into your paint, and begin spreading it across the surface. Apply the topcoat the same way as you applied the primer, looking out for missed spots, streaking, and pooling paint. Dab the hard to reach areas thoroughly as well. Wait for the paint to dry and apply a second coat if needed.

Apply Sealant

Since your fence is regularly battered by the elements, it’s a good idea to finish the job with a sealant to keep your paint looking great. Look for a sealant that is designed to adhere specifically to painted metal.
