Aluminum/Steel Siding Painting

Refinishing of Steel/Aluminum/Metal Siding on Commercial & Industrial Buildings

At Induspray, we specialize in aluminum, steel and metal siding painting services that transform aging or weathered exteriors into like-new surfaces. Our team serves the Greater Toronto Area, providing professional-grade siding refinishing for commercial, industrial, and institutional buildings. If your facility’s siding looks faded, oxidized, or stained, repainting is the most cost-effective solution to restore curb appeal, extend siding lifespan, and protect your building from further damage.

Trusted Aluminum/Steel/Metal Siding Painting Contractors

Induspray is one of the most experienced aluminum, steel and metal siding painting companies in the Toronto region. With over 50+ years of expertise in industrial and commercial painting, we’re known for completing high-quality refinishing projects safely, on time, and within budget.

Our team includes licensed and insured professionals who understand the unique requirements of aluminum and metal siding. We tailor our approach to suit each structure’s specific condition, use, and exposure.

Why Choose Aluminum Siding Painting Over Replacement?

Full siding replacement is expensive, time-consuming, and disruptive. Aluminum siding and steel roof painting offer a significantly lower cost alternative, delivering beautiful, long-lasting results in less time and with less environmental impact. Our high-performance coatings are designed to adhere to metal substrates, resist UV fading, and provide long-term protection against harsh weather.

Benefits of Aluminum/Steel Siding Painting Include:

• Improved property appearance and professional image
  
• Resistance to corrosion, fading, and environmental damage
  
• Prolonged life of siding material
  
• Greater energy efficiency (reflective coatings available)

Our Proven Aluminum Siding & Metal Siding Painting and Refinishing Process

1. Detailed Surface Preparation

We start with industrial washing to remove dirt, chalk, mildew, and oxidation. Proper prep ensures the new coatings bond tightly to the surface for long-lasting durability.

2. Priming and Masking

When required, we apply metal-specific primers to boost adhesion and corrosion resistance. Surrounding surfaces like windows, signage, and landscaping are protected during the process.

3. Precision Paint Application

Using advanced airless spray systems, we apply factory-quality coatings in a smooth, uniform finish. Our paints are color-matched and customized to your facility’s needs.

4. Final Inspection and Quality Control

We perform thorough inspections post-application to ensure complete coverage and customer satisfaction, followed by a full cleanup of the job site.

Everyone wants a paint job or refinishing job to last as long as possible. This task is made more difficult with exterior exposure, since paint finishes have to deal with sun, rain, temperature fluctuations and more, all of which wreak havoc with a paint finish.

Nowhere is this more of a problem than when refinishing exterior steel/metal clad or aluminum clad siding on a large industrial or commercial building. Particularly in the spring and fall when daily temperature variations are the highest, the metal substrate heats up and expands during the day, while at night it cools and contracts considerably when compared to any other painted surface.

Siding Coating & Refinishing Systems

This means the coating used for industrial building siding refinishing has to be designed for high levels of expansion and contraction, or it will soon crack and fail as it is stretched beyond its capabilities. Highly flexible coatings are required, combined with excellent fade resistance and gloss retention to withstand the sun exposure.

Coating selection becomes even more important when dark colours are being used since they absorb more heat during the day; the dark surface can become over 50 degrees F hotter than a comparable light-coloured surface. As well, fading is more noticeable on dark colours, so colour retention characteristics are more important.

Regular industrial paints generally don’t have the high quality inorganic pigments, resins, or correct gloss levels required to duplicate the original factory finishes. If the refinishing is to match the original factory finish in both gloss and colour, you also need to make sure the gloss of the refinishing enamel is correct.

At Induspray, our refinishing enamels for metal/steel/aluminum siding applications are custom made for us by the original coil coating manufacturers to the much higher performance criteria of the original coating specifications.
