The appearance of your property has a significant impact on the impression that is made and how people view your business and services. For this reason, maintaining the appearance of your property is vital to making good impressions to potential clients and as well as employees.
There are multiple ways in which you can improve your business, and sprucing up your cladding is one of the most common. Cladding spraying and other on site spraying services can help you to rejuvenate your property and give it a new lease of life. While you are maintaining your property, it is important to make sure that you protect it against future damage with cladding coatings. One of these effective coating methods is powder coating galvanised steel, which is a two-step coating process that provides a protective barrier against adverse weather.
If your property is looking a little worse for wear, then you should consider repairs on your exterior, and even interior cladding. To help your property stand out for all the right reasons, here is a simple, all you need to know guide about powder coatings.
Powder Coating Galvanised Steel: A Just Spray Guide
Although powder coating and galvanising are two separate services, both of which are important to the protection of your cladding. When having these coatings applied to your property, it is important that you have a professional team work on your cladding. Just Spray has years of experience in dealing with diverse cladding repairs, so you can be sure that our helpful and friendly team can find a way to rejuvenate your property.
The first step to understanding how powder coating galvanised steel can help with the appearance of your cladding is to know the difference between powdered coatings and galvanising. So here is a helpful guide for everything you may need to know about the differences and how they can change and benefit your property.
What Is Powder Coating?
Powdered coating is a dry form of paint that is usually used on steel and aluminium as a layer of protection and coat of vibrant paint. When you opt for powder coating, you are able to mix and match on colours to form your perfect shade, and even colour match existing colours on the property. Not only will it give it a fresh coat of colour, but it also acts as a form of protection against corrosion. Corrosion is most commonly found on metal claddings and can be the result of cut edge corrosion. When cladding is first manufactured, it is covered with a protective layer that prevents it from suffering from rust and corrosion. However, when your cladding is cut to fit around your property, the edges of the cladding no longer has that protective layer, leaving it vulnerable to what is known as cut edge corrosion.
One of the most common methods for applying powder coatings is through spraying; this method propels the coating onto the cladding while giving an electrostatic charge in the process. The cladding is grounded of which will attract the electrically charged particles allowing them to bond themselves to the material. UV light is then used to cure the powder so that it bonds even more with the material, giving it a vibrant and glossy finish.
What Is Galvanising?
Much like powder coatings, galvanising protects your cladding from corrosion by adding a layer of anti-corrosion properties onto your cladding. This protection is formed through a thin coating of zinc onto metal, helping you to shield your property from environmental conditions such as rain. With a coat of galvanising, the cladding will have an almost silver, metal and shiny appearance, making your property stand out, particularly with the sun is shining.
Galvanising is the process of dipping metal materials into hot molten zinc to form a protective layer from scratches and moisture damage. It usually only takes about five minutes to coat cladding, and it will then be left to cool to give it that shiny, smooth coating. For a quick seminar on how galvanising works, take a look at Galvanise It’s detailed guide on the galvanising process.
How Is Galvanised Steel Prepared For Powder Coating?
Preparing your cladding for the layers of galvanise and powder coating can be extremely difficult to ensure that the powder coating comes out as effective as possible. For this reason, it is important that you make sure to call in a professional team so that your coatings are applied with expert skills and protects your cladding efficiently. When Just Spray complete cladding coatings, a strict process is carried out, here is a rough guide on how your cladding is prepared:
- The first step is to prepare the cladding for the first process of coating, which will be the galvanising with zinc. Any damage or defects to the cladding should be removed before anything is applied to the material, this is rectified approximately 12 hours within the galvanisation process.
- The cladding is then thoroughly cleaned and dried using products that are not high in acidity. If highly acidic solutions are used, then it could result in striping the zinc from the surface.
- Care must be taken not to remove the zinc layer from the surface, as this can dramatically affect the outcome of the powder coating.
- The cladding will then be primed before the powder coating is applied, to ensure the best finish to your material.
If you would still like to know more about how galvanised steel is prepared for powder coating, take a look at the Wagner Companies useful guide. Preparing materials for powder coating is a complex and advanced process, so it is vital that you do not attempt this yourself, and be sure to contact our team for more information about our powder coating services.
Are Their Problems That Might Occur?
As it is with any cladding maintenance, there are a variety of problems that may occur when you do not carry out these projects through a professional team. A skilled and expert team will know exactly how to avoid these problems, making it extremely unlikely for them to occur. However, when you decide to carry this out by yourself or place trust in a company that has little experience, you may find that your powder coating does not stick, or it looks messy and uneven.
There are four main problem areas that are common with powder coating on galvanised steel. These problem areas are likely to arise if preparation that was discussed previously is not completed efficiently. Here are the four problem areas and the damage they can cause to your cladding:
- Poor Adhesion – When cladding is properly prepared, grease and dust are removed from the surface, allowing it to bond with the material. When this is not carried out, you may find that the paint does not stick to the material and could even let in moisture, causing peeling and cracking in the future.
- Pin Holing – This is where gasses are trapped between the metal and powder coating as it is cured.
- Aesthetics – Various paints will have a different reaction to the metal, meaning that you will need to ensure that the paint you use works on various metals. Gloss finishes, when the cladding isn’t prepared properly, can also highlight the imperfections in the metal, making it look even worse than it is.
- White Rust – When your cladding that has been galvanised is stored and shipped, it can form a white film over the top. This is a result of moisture and water not drying quickly on the material and therefore could benefit from a powder coating for further protection.

You can also find other ways to reduce risks associated with powder coating on the government website which includes tips on health and safety.
When To Consider Powder Coating
Powdered coatings are most commonly used on metal materials as it is able to bond itself to the cladding, making it perfect for a thick layer of protection against various damage. Just some of the types of protection that powdered coatings offers includes:
- Heat damage
- Cold damage
- Moisture damage
Giving your property a vibrant coat of paint is also one reason that you may consider using powdered coatings. As previously discussed, powdered coatings offer you a whole host of different colours that can be mixed and matched to your property. These coatings are also available both inside and outside your property, meaning that you can opt for a neutral colour outside and go for a bright colour on the inside. When it comes to interior powdered coatings, you can have them on cladding, walls and even cabinets, so design ideas and styles are endless.
Overall, the best time to consider having powdered coating is when your property needs a rejuvenation. With a simple coat, you can completely transform your property, inside and out, making it ideal for giving any property a new lease of life. You can find some unique ways to use powdered coatings on Clever, where everything, from taps to cupboards, has been coated with a dash of colour.
