A Simple Guide to Spray Painting Cladding and Corrugated Metals

Cladded and corrugated metal surfaces are the perfect candidate for spray painting. If you have these kinds of surfaces it’s likely there are gaps, nooks and crannies that are hard to reach with an ordinary paint brush.

By using a paint sprayer you can make sure that you cover all areas with a nice, even finish. It’ll even save you time and give you a more professional look!

You don’t have to pick a dull colour either. You could use bright colours to give your property personality. All you need is the right tools!

Prep and Prime

Before you delve into coloured topcoats you want to make sure your surface is ready for the paint. By using a good primer you’ll be able to get a longer lasting and harder wearing finish.

We recommended using Rust-Oleum Mathys Metal Cladding Primer on any bare areas of metal first, it’s not required for areas that are previously coated with Plastisol® or similar but it is good practice and will only improve the overall job and long term performance. This water dilutable coating can be applied to metal cladding, even when it’s weathered helping to protect it from any further oxidisation! It’s a high-tech primer, giving you the best protection on metal cladding and other surfaces including: bare steel, blasted steel, galvanised steel, zinc and aluminium.

This primer dries extremely quickly so you will be ready to spray paint over it in just one hour! Once dry, you’ll have extended the lifetime of your cladding by up to ten years – a cost effective solution.

Protective Finish

Here’s the fun part! After you have a well primed surface you’ll want to get painting. If you use the wrong paint on metal you’ll notice it flakes, bubbles or cracks quickly, leaving you with paint peeling away from the metal. Not a good look!

Try using Rust-Oleum Mathys Metal Cladding Topcoat. This topcoat works hand in hand with the primer we just mentioned, you can be guaranteed the final look will be great. The new formula will help to improve the lifetime of your cladding as well as the primer. It comes in a wide variety of colours, so you have the chance to be creative and even go bright.

By using a spray painter, you can achieve a nice, even finish on your cladding or corrugated metals, catching all those sections that are sometimes hard to miss. As long as the surface is primed and you use a good topcoat, you’ll give your surface an instant makeover.

Rust-Oleum’s new improved formula for the Metal Cladding Topcoat means it has higher filling and hiding power and features excellent flow out with high durability and colour and gloss stability which subsequently means it can be applied directly to exterior Plastisol wall cladding surfaces that are in good condition (speak to our Technical Department for advice). This provides an extremely cost effective solution to painting cladding when just a simple colour change or rejuvenation coat is required.

Now it’s time to get painting! If you need any help with spray painting or alternately support for painting wooden cladding, just ask the experts at Rawlins Paints.
