These outdoor railings painting tips will improve the appeal of your home. Especially if yours are starting to peel or chip.
Up for the challenge? This step by step guide provides all the ideas for painting railings too.
What Are Your Outdoor Railings Made From?
So how to paint metal railings, you ask? Before we divulge, try to identify the type of metal that has been used in yours.
The most common include traditional cast and wrought iron, modern stainless steel and aluminium too. Wrought iron is often the material of choice for its durable strength. If regularly maintained, it will last you for years. Where paint has worn away, however, the exposure to water and air can result in deterioration and rust. Whichever metal you have, our exterior paint will achieve a nice, flawless finish. This also goes for other outdoor metalwork too, like pipes and tables. Whatsmore, it’s low-VOC and water-based.
When Should You Paint Your Outdoor Railings?
As with all types of painting outside, it needs to be done before the previous coating has begun to fail. If your metal railings are too far gone, it’ll make them a nightmare to paint. This job is bad enough as it is. Types of damage include corrosion and rust. These will make it a pain in the arse to get that new COAT on smooth. Your best bet is to do an annual check where you assess the paintwork. If it looks thin and worn, it’s time to paint. Obviously, there may come a time when metal railings need to be changed. For example, have they got any serious vehicle damage? Sometimes they can even deteriorate to the point that paint and primer won’t do. Especially after years of being exposed to British weather conditions. Nice.
How To Prepare Your Outdoor Railings For Painting

Brush Off Old, Flaking Paint
Next, we’re gonna grab that steel brush. Or a scraper. This is important for removing flaking layers of old paint. You also don’t need chemicals or power tools to do this bit right. We’re all about keeping things as simple as poss. Use your paint scraper to work on the flat railing sections. Where the scraper can’t reach, your stiff-bristled wire brush will be just the ticket. Skip this step, and the new paint won’t adhere or protect the metal. Pretty pointless since you’ve come this far.
Clear Moss And Weeds
If your railings have also become the victim of moss, scraping will help, but it won’t prevent this and algae from returning. Grab yourself a safe and effective algae cleaner. The web is full of chemical-free wonders. Check the bottom of railings and also clear away weeds. Often there’s a gap at the bottom of railings where debris can collect. This moisture trap can encourage corrosion as essentially the metal never dries out. Get in there with your scraper and give it a good old clean.
For this next part, you’ll need to grab your sandpaper and slightly wet it. Wet sanding is a great way to remove deep scratches without creating loads of dust. As the water acts as a lubricant, it’s less abrasive than dry sanding and will result in a much smoother finish.
Clean Away Grease And Grime
In this step, you’ll need to get your marigolds on and clean the surface. New paint won’t stick to a lifetime of grime. Sugar soap will cut through this great if you have the stuff in. Or you can use a mild mixture of soap and water instead. Using a cloth, wash the railings to get rid of dirt and any greasy deposits. For hard to reach places, an old toothbrush will work. Simply dip in soapy water and work into crevices. Once you’ve had a good clean, rinse your railings. The hose will make it nice and quick.
Prune Nearby Plants And Test Paint
Now that your railings are clean, it’s time to have a prune of those plants. The last thing you want is vegetation getting in the way. This will make them stronger next year and keep your shrubs in great shape. Make sure your clippers are rust free and nice and sharp. If you’re also painting over existing old paint, you’ll want to make sure that it takes. Paint a small trial section and leave to dry overnight.
Protect Plants From Paint Splashes
Got any funky planters outside? Don’t trim these. Protect them instead with cardboard. This will do a great job of protecting their leaves from splashes of paint. Otherwise, you’ll have A LOT of cleaning up to do when you’re done. A good masking tape will help you hold it in place, while you get that paint on. Any pro painter will tell you a bit of planning is all that’s needed with this. As long as the cardboard has drainage and/or air holes, your plants should be fine to sit tight until the paint has dried out.
Make Final Preparations
Next, it’s time to put that old newspaper to use to protect bricks, pillars and paths. Like plants, you don’t want them covered in paint. Hold it in place with a good masking tape to keep things tidy. Our quality decorator's tape is an absolute must-have for painting metal railings. You’re also best painting on a warm, slightly overcast day. Never paint in the rain or wind, for that matter too. In fact, avoid Nov to Feb. This is not the right time. Winter is too cold and damp for paint to cure properly anyway.
How To Prime & Paint Your Outdoor Railings
Get That Primer On
Ideally, if you can, prime right away. You don’t wanna leave iron railings exposed for too long. Unprotected from paint, they can quickly become damaged. So lay down those dust sheets, and let’s get priming. When painting metals, especially ferrous types, primer is an absolute must. This is because they're more prone to rusting than others thanks to their iron content and so priming will help the paint adhere to the metal. Although COAT paints are generally self-priming, this additional layer will give the paint an extra boost of grit. It’ll also increase the metal's resistance to rust and protect the surface. We recommend our multi-surface primer for painting metal railings.
Brush On Two Coats Of Paint
Once the primer has dried, get that paint on! This is where you’ll really see your railings come to life. Begin by applying two coats with a small paintbrush. Starting from the top and working your way down the railings. Be careful to keep your coats nice and light rather than thick. This will dry unevenly and can look gloopy. It’s also really easy to miss certain spots when painting railings. Be sure to check your work from different angles as you go along. Also, keep an eye on underneath the railings. Your biggest enemy here is drips. These can occur when you load your paintbrush too much. To maintain your new paint job, wipe your railings once a year with a little white vinegar and a clean cloth. This will stop any rust in its tracks and keep them gleaming until you come to paint them again.
