Over the course of a couple of years, you can expect to see a significant amount of fading over windows and panels coated with powder coatings. Unfortunately, due to British weather, it is more likely to deteriorate at a faster rate, due to all the rain and sunshine. Throughout this article, we are going to discuss why powder coating may fade and the different ways to prevent it.

What can we do to prevent powder coating from fading?

Many commercial spraying coatings will have a limited life expectancy which means overtime to coatings are going to fade and deteriorate. However, the usual life expectancy for commercial powder coatings is around five to ten years, depending on which powder coating has been applied.

There are so many potential causes of faded coating systems however one of the main reasons you will experience powder coating deterioration is the natural elements it is exposed to every day. If your commercial property is located in a coastal area, due to harsh weather conditions your premises may be more prone to powder coating deterioration.

Unfortunately, the UK’s climate is so unpredictable we cannot always stop fading from occurring, therefore decreasing its overall lifespan. As our buildings are exposed to a wide range of weather conditions, there are a few preventative coatings you can use to stop damage from UV light. Sun exposure or direct sunlight breaks down the particles within the paint which then makes the coating fade. By applying a special UV coating, you are effectively applying a coat of sunscreen to the exterior of your property. Not only does it decrease the rate of fading but it also prevents the paintwork from bubbling or flaking.

If your commercial property is located in a large town, city or industrial estate, it will be exposed to pollutants. Built-up areas are more likely to have pollutants from increased machinery use and cars. When contaminants are released, they sit in the air and in rainwater which can degrade the overall finish of each coating, therefore, affecting the brightness and vibrancy of the colour.

Another thing to think about is the colour of the powder coating you have on the exterior of your property. Certain colours will be effected by fading a lot more than others, for example, reds and blue loses its vibrancy a lot quicker than subtle colours.

Bird droppings should also be thought about; they can have a significant effect on the way your powder coating looks. For birds to decompose the food it eats, the bird’s body produces uric acid which has relatively high pH level. When a bird decides to relieve itself on the exterior of your commercial property the uric acid eats away at the top layer of paint. Over time the uric acid will react with carbon in the air which breaks down the paintwork leaving it patchy, flaky and bubbly.

How to Prevent Faded Coatings

There is a range of things you can do to help protect your powder coating from fading. Ensuring your powder coating is regularly cleaned in the right way and with care will dramatically increase the standard and quality of the powder coating and the material.

Regular maintenance and care inspections will also help towards increasing the lifespan of your coating. If you find that your commercial property has a number of defects take the required action to deal with them, by leaving it over an extended period of time you are only increasing the damage.

Cleaning

When it comes to cleaning powder coating, you have to be very careful with the tools you choose. We always recommend avoiding power washers or pressure cleaning equipment. If you do use a pressure washer, you can damage the paintwork which will increase the rate of which it fades, therefore only resulting in one thing, regular panel repairs or replacements which can be costly in themselves. Another thing to note is harsh chemical should not be used on powder coated panels, not only can it damage the coating itself but it could also affect the material underneath it, affecting the overall finish. We recommend staying away from any products containing chlorine or any other harsh chemicals.

Respraying

One of the best ways for your organisation to increase the lifespan of your powder coating and panels is to consider having a respray or on site spraying. If you have the powder coating applied by a certified contract it will be done perfectly leaving you with a more durable surface. It will also make the colour look significantly better with increased vibrancy.

Coatings

Another type of coating you may want to consider is having a clear coating applied. If you have a vibrant or rich colour coated on the exterior of your commercial property, a clear coat will seal and hold the colour in. It is also a great way to slow down the fading process as well as deterioration of colour and material.

Benefits of powder coatings

One of the main benefits of powder coatings is the durability it provides to your cladding panels and curtain walling. Another thing to think about is that it can be applied to a number of materials such as automotive vehicles, architecture, appliances and other everyday products all coated with metal or plastic.

Many liquid based paints hold a number of harmful solvents which can add to pollution, this means if your business is looking to become more eco-friendly using powder coating to paint the exterior of your property is a great way to do so.

Why should I choose powder coatings

Powder coatings are a great option for your commercial property if you are looking for something that is durable. By staying on top of regular maintenance, you can dramatically increase the lifespan of the material as well as the coating. Cleaning is also another aspect many people forget about, every couple of months ensure your exterior building has had a deep clean to get rid of any acid rain or bird droppings.
