Painting Exterior Metal – The Ultimate Guide

How To Paint Rusted Metal

1. Preparation is key for painting on to a rusted metal surface. First clean the surface down using a wire brush dipped in solution to remove any unwanted surface grease, oil, dirt build up.
2. After cleaning, attempt to reduce as much of the rust on the surface as possible again using the wire brush. This will create an easier surface to apply to. Not all the rust will be able to be removed and this isn’t a problem. Use a light key sandpaper to sand down the surface to allow the paint to better adhere.
3. After removing any flaking paint and rust that can be removed, priming the surface is essential. Apply one-coat of Combicolor Anti Corrosion Primer to the surface using a paint brush, ensuring a thin and even coating.
4. After applying the primer, the process of painting can either be done using a standard paint brush or roller, depending on what exterior surface you are painting. Apply two-coats of the paint according to the manufacturer’s instructions, leaving it dry completely between coats.

Things To Consider When Painting Outside

When painting exterior metal, it is important to consider:

• Rain – painting anything outside runs the risk of being affected by the weather. Paint is very particular about the conditions it can be applied effectively in, with rain affecting paint application causing it to run. Plan ahead so you have enough time to allow the paint to fully dry in-between coats, which should ideally mean you leave two days to fully complete the project.
• Paint when cloudy – many people believe the best time to paint is in the peak of summer, however this is not the case. The best weather to paint in is a mild day that is overcast, as the sun can make it difficult to paint in, not only as it will cause glare, but because when using a water-based paint, the paint will dry too quickly to get an even finish

Q. How much is metal paint?

A. The price of metal paint can vary, but both of the metal paints we recommend here at Painters World are between £40 to £50 for 2.5L. This is because they are high-quality and durable exterior paints that will last much longer than a standard metal paint. Contrary to popular belief, using a high-quality paint will save you both money and time, as they will require less painting to cover the surface. While it can be tempted to opt for a cheaper option, you will get what you pay for and will ultimately have to repaint the surface in a matter of years, which will double the time it took to paint and double the cost of materials.
