A Simple Guide to Spray Painting Cladding and Corrugated Metals

How-to-Spray-Cladding-2

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

How-to-Spray-Cladding-3

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.

  1. I am interested in using your materials on painting some exterior cladding ,what type of spray gun and what type of spray needle would be required. for your topcoat

    • Good morning John,

      Sorry for the delay in responding to your comment – we have just come back from our seasonal shut-down.

      If you wish to apply Rust-Oleum Mathys Metal Cladding Topcoat you must do so by airless spray. Nozzle: 013 – 015 / Pressure: 160 bar. If necessary dilute with water.

      Best regards.

  2. I have a shower stall that is made if corrugated metal. I want to paint it another color. I can’t afford a spray gun so can I use spray paint that is used for appliances? Or is there something different to use?

    • Hi Sheila,

      Many thanks for the question. As there will be direct water contact on a shower enclosure, we would recommend a 2 pack system for this application. We have not previously heard of a shower enclosure made out of corrugated metal and as we are unable to say for certain if it is bare mild steel, galvanised, or coated the best advice we could give would be to apply Rust-Oleum 9200 Rust-O-Thane as a topcoat – this is likely to be OK if applying over an existing coating.

      If the shower stall is galvanised or powder coated, then the following primer would be needed:

      Rust-Oleum 3333 Super Adhesion Primer

      If it is bare mild steel, then the following primer would be needed:

      Rust-Oleum 9170/9180 Epoxy Metal Primer

      I hope this helps, if you need any further assistance or any more detailed advice please feel free to contact our Technical Department on 0113 2455450 (option 2) or send a message to [email protected].

      Many thanks

    Sirs.We have two cottage roofs apex shaped approximately 6m x 5 m built in 2010 with powder coated corrugated sheets. The power coating is partly peeling off .

    We are located in Devon. Do you have a product that could be used to repair the peeling and can you recommend a contractor in this area to carry out the work .

    Thanks

    • Hi James,

      Thank you for getting in touch. I’m afraid we don’t offer any products that would repair the peeling paint, if it is failing then we would recommend the existing coating be completely removed back to a sound edge before application of another paint coating.

      We would normally recommend it be pressure washed with the use of Rust-Oleum Mathys ND14 to clean and degrease, then using a grinder on the edges of the paint back to a sound edge before applying Rust-Oleum Mathys Noxyde Peganox.

      We’d recommend patch priming the bare metal with this product before applying 2 coats over the whole roof.

      I’m afraid we wouldn’t have a recommended contractor to pass details of due to the size of the project.

      I hope this helps, and please feel free to get in touch if you have any further questions.

      Many thanks

  4. My husband wants to use corrugated metal for a backsplash behind our stove. What paints, if any, would you recommend for ease of cleaning.

    • Hi Sally,

      Thanks you for getting in touch.

      The main issue we could foresee would be that we don’t supply any products which would be suitable for direct heat contact. Therefore, if it is a gas stove then the paints we could offer would not be suitable, unfortunately.

      If it is an electric stove then it could potentially be possible to apply Rust-Oleum CombiColor to achieve the desired colour and then overcoat that with Rust-Oleum 4900 Polycoat 2K which would make the surface easily cleanable and provide a more durable finish.

      We would advise contacting our Technical Department on 0113 2455450 (option 2) or send a message to [email protected] before making a purchase or carrying out any work.

      Please be aware that both products mentioned have no information regarding direct food contact.

      I hope this helps and please feel free to get in touch if you have any further questions.

      Many thanks
      Stuart
