One of the best things about Colorbond fencing is that there is very little maintenance involved. Unlike traditional timber fencing, Colorbond steel rarely has to be cleaned, capable of withstanding even the harshest of Australian weather conditions. However, there are a few situations where your Colorbond fence may require a bit of upkeep. In this article, we'll take a look at exactly what these situations are and how you should respond.

1. Basic maintenance

As mentioned, Colorbond fences will last an incredibly long time without cleaning, but it certainly doesn't hurt to do a little basic upkeep in order to keep it your fence looking its best. Try simply hosing it down periodically with water -- you can do this while washing your car or watering your garden. You should also check for cobwebs and wipe them away with a broom. Finally, make sure soil or garden fill doesn't build up against the bottom of your Colorbond fence, as the water retention may eventually lead to corrosion.

2. Preventing corrosive flue deposits

Do you have a chimney on your home, or perhaps on the roof of one of your neighbours? Or a water heater with a flue (exhaust) pointing towards your fence? If not, then you won't have to worry about this section. If you do, however, pay close attention. The fallout from fireplaces using wood, oil and other fuels can be potentially damaging for a Colorbond fence. Where possible, ensure the flue points away from your fence -- this might mean ensuring it is high enough for prevailing winds to carry most of the deposits over the top. Corrosion is related to high concentrations of sulphurous products and wood acids, so check for these when buying fuel products.

3. Identifying and removing fungus

Fungal growth can occur on pretty much any surface and, despite its many strengths, Colorbond is no exception. If you suspect fungal growth on your fence, try a spot test with sodium hypochlorite solution such as household bleach. If fungus is present, it will be destroyed by the bleach and the area will be clean. If it's not destroyed, it's probably just dirt. Ensure that hypochlorite solutions are above 3 per cent, and be sure to wear gloves when using it as the solution is very alkaline. Make sure you wash the fence area down with water afterwards, too, as the lingering effects can harm children, pets and wildlife.

4. Removing graffiti

The bane of mild-mannered homeowners around the urban world, graffiti is an ever-present threat, even if it doesn't look all that great on Colorbond fencing anyway. While there are many graffiti removal products on the market, be aware that using many of them will void your Bluescope warranty. This includes chemicals such as Acetone, Methylethyl, Ketone, Toluene, Thinners and commercial paint. Remember, Bluescope has very strict guidelines when it comes to graffiti removal without voiding your warranty. Using the product DuPont Graffiti Remover is one way to ensure your warranty remains intact, as the product has been proven effective and approved by Bluescope. Generally, your fencing contractors will be able to provide you with this product, but it can also be purchased from most Bunnings Warehouse locations.
