Why is Powder Coating good for Billboards?

Billboards are a great form of advertising for any business. They are big, bright and can be seen from miles around. The problem is that, over time, painted billboards can start to look tired and faded. This will make people believe your business is tired and faded.

That’s why many businesses are turning to powder coating for billboards. 

What is Powder Coating?

Powder coating is a type of metal finishing first developed in North America in the 1960s. It’s applied as a free flowing dried powder, it can be used on mild steel, galvanised steel and aluminium, and it produces a high quality durable finish with almost limitless colours.

It’s resistant to everyday wear and tear and, as there are no solvents used in the process, it’s less damaging to the environment than paint. Unlike paint, it emits very little volatile organic compounds (VOCs) into the atmosphere, and so is a natural choice for those concerned. 

How Does Powder Coating Work?

A mixture of polymer resin systems with pigments, curatives and other additives are melted together and then cooled, before being ground into a powder similar to flour.

Then a spray gun is used to apply an electrostatic charge to the powder particles, which are in turn sprayed on the item you want powder coated.

Why Is Powder Coating Better Than Paint and How Long Will It Last?

There are many reasons why powder coating is better than painting. Due to the thermal bonding process it undergoes during curing, it can be applied in a much thicker layer than paint. Therefore it is resistant to chipping, scratching, and other wear and tear.

After applying powder coating, you don’t have to go back for touch ups. Powder coating done well can last up to 30 years.

What Is the Difference in the Cost of Powder Coating vs. Painting?

Generally, powder coating is initially slightly more expensive than painting, but in the long run powder coating will work out much cheaper. It gives you a coating that is about twice as thick as normal paint, so doesn’t require ongoing maintenance. Therefore, your initial cost is a one-off payment that will last for many years. 

Why Is Powder Coating Good For Billboards?

Billboards work to advertise your business 24 hours a day, 7 days a week and 365 days a year, so you need them to stay bright and vibrant. 

Powder coating is resistant to rain, ultraviolet light, chemicals, impact and any extreme weather conditions.

Having a powder-coated billboard reduces the risk of the sign becoming faded or corroded. They retain their colour and gloss, while being easy to hose down to clean.

Powder-coated billboards are tough, look great and will last you for a long time.
