Dealing with Rust
Rust can be a costly and sometimes catastrophic issue that affects metal surfaces, compromising both their strength and appearance. Understanding rust and how to manage it is crucial for maintaining the integrity and lifespan of metal structures.
Rust occurs when iron reacts with oxygen and moisture, leading to the formation of iron oxide. This process can be accelerated by environmental factors such as humidity, salt exposure, surface damage (wear and tear, impact defects, abrasion from cleaning equipment, etc.) and temperature fluctuations. Properly addressing rust involves identifying early signs, such as discoloration and pitting, and taking preventive measures to protect the metal.
Your 3-step guide to understanding, diagnosing and getting rid of rust is:
- What is Rust?: Rust, or iron oxide, is often a reddish-brown colour which flakes off easily, exposing the underlying metal to the elements and furthering corrosion.
- Spotting Rust: Look for discolouration, pitting, and flaky surfaces. Early rust appears as small spots or streaks, while advanced rust can cause significant structural damage.
- Preventing and Fixing Rust: To combat rust effectively you must remove all traces of rust from the metal surface. This can be done by a number of methods but most commonly it is done by blast cleaning or hand/power tools such as wire brushes or sandpapers.Once removed, the bare metal surface should be re-coated with the same paint specification of the surrounding areas not affected by rust.
- High-quality rust converters and anti-corrosive paints can prevent future rust by forming a protective (and decorative) barrier.
Moisture and Metal
Moisture is one of the leading causes of rust and corrosion in metal surfaces. When metals are exposed to damp or humid conditions, the presence of water molecules accelerates the oxidation process, leading to rust formation. Moisture can come from environmental exposure, such as rain or humidity, or from condensation in poorly ventilated areas. To effectively protect metal surfaces from moisture, it is essential to use high-quality waterproofing metal paints and ensure proper surface preparation and maintenance.
Areas that may be subject to risk from moisture damage are metal roofing, metal guttering, roofs and walls inside shipping and storage containers/units, garage doors, agricultural machinery, automotive vehicle undersides and rims, metal doors and window (frames), mezzanines, and commercial racking, storage and shelving.
- Waterproof Paints: High-quality and specialist metal paints available at Rawlins Paints will ensure that moisture cannot penetrate the paint layer and reach the metal - when applied correctly to suitably prepared areas.
- Proper Ventilation: Ensuring areas are well-ventilated to reduce dampness and moisture build-up will vastly improve the lifespan and integrity of metal, and also aid colour retention. For areas where ventilation cannot be improved, you must implement a regular cleaning schedule.
Types of Metal Paints
Choosing the right type of metal paint is crucial for achieving the desired protection and 'aesthetic' results. Metal paints come in various formulations, each designed to address specific needs and conditions. From eco-friendly water-based options to highly durable solvent-based paints, understanding the differences can help you make an informed decision.

Metal Paint FAQs
What is the best way to apply metal paint?
The best method depends on the project size and type. Brushes are ideal for small, detailed areas; rollers are suitable for large, flat surfaces; spray guns provide an even finish and are efficient for large projects. Ensure you follow the manufacturer's instructions for optimal results.
How do I prepare a rusty metal surface for painting?
For best results blast clean to the relevant industry standard as per the manufacturers guidelines of the metal paint you’re intending to use. If blast cleaning isn’t possible, select a metal paint that is OK to be applied to hand/power tool cleaned metal. Thorough scraping, wire brushing, disc sanding, etc. to remove all loose scale, rust and other material. Dust off and clean the surface with a degreaser to remove contaminants. Immediately begin to apply the chosen paint system so no flash rusting occurs on the newly, bare prepared metal.
Can I paint over old metal paint?
Yes, as long as the old paint is in good condition, well adhered and is compatible with what you intend to apply next. Abrade the surface of the existing paint with sand paper to ensure proper adhesion and remove any flaking paint. If necessary, apply a primer to any areas back down to bare metal before applying your new topcoat over everything.
What is the difference between water-based and solvent-based metal paints?
Water-based paint uses water as the primary solvent to dissolve the binders and pigments. It typically contains acrylic, vinyl, or latex resins as binders, along with various additives to improve performance. This type of paint is easy to apply, dries quickly, and typically can be cleaned up with soap and water. Water-based paints usually have low odour and emit fewer volatile organic compounds (VOCs), making them a more environmentally-friendly choice, and possibly more suitable for indoor use.
Solvent-based paint, also known as oil-based paint, utilises organic solvents like mineral spirits or turpentine to dissolve its binders and pigments, which are often alkyd, polyurethane, or epoxy resins. Solvent-based paints may require more careful application and cleanup with chemical solvents. They can dry more slowly than their water-based counterparts which can be advantageous for achieving a smooth, glossy finish where desired. However, they can also have a strong odour and higher VOC emissions, posing greater health and environmental risks, especially if applying indoors.
Check out our blog post 'What Is The Difference Between Water-Based And Solvent-Based Paints?' for more info.
Do I need a primer for all metal surfaces?
