A focus on long-term adhesion: ensuring durability and sustainability in architectural spray painting

When it comes to architectural spray painting, achieving long-term paint adhesion remains a challenge for many applicators. Despite advancements in paint technology, the complexities of the chemistry behind different paint materials and substrates can lead to adhesion issues that compromise the durability, appearance, and sustainability of the finished product. This can cause delays and costly repairs, ultimately impacting the overall success of a project.

At ORS, we have built a reputation for delivering high-quality workmanship by leveraging our experience to overcome both common and rare adhesion difficulties which may not present themselves until long after the project is complete. This is reflected in the thorough steps we take to ensure that every one of our projects stands the test of time.

Steps to ensure long-term adhesion

On site architectural spray painting has the potential to be a highly effective and time-saving solution for refurbishing and extending the life of a building envelope. However, achieving these outcomes requires time-earned expertise and experience. We recognise that the success of our projects hinges on a combination of factors, so our team has come together to outline a few of the critical steps we take to ensure long lasting finishes:

Step 1: Checking weather radars

Weather conditions such as rain, wind, temperature, humidity, and fog can all affect the overall outcome of any architectural spray painting project. This is why our team keeps a close eye on weather radars, allowing us to schedule work during appropriate conditions. This reduces the risk of adhesion issues caused by moisture or temperature fluctuations.

Step 2: Comprehensive preparation process

Before we begin any project, we complete a thorough preparation process which can include various different tasks dependent on the requirements of the project and the condition of the substrate. When it comes to wall cladding, we may suggest high pressure washing of at least 3000 PSI to existing cladding sheets and grinding rust back to bright, shiny metal (ST3 standard). In the case of powder coated aluminium such as curtain walling or shop fronts we will be filling in redundant screw holes (which can sometimes require filling a 2nd and 3rd time) as well as abrading the surface to provide key. We will also undertake a thorough and meticulous masking process to protect surrounding items and areas as well as creating immaculate paint edges.

Taking the time at the start of a project to complete these processes creates a prepared, stable surface that is receptive to the new paint system for better long term adhesion.

Step 3: High-quality paint

We only partner with trusted associates that we know we can rely on for the best results. These include Lechler, Cromadex, and Tikkurila, who provide us with top-quality paints specifically designed for various architectural applications. Not only do we focus on high quality paints, but we have the unmatched knowledge required to specify the right system, depending on the specific requirements of the project.

The steps we take to ensure a high-quality finish are just part of our commitment to delivering exceptional results.

But why is long-term adhesion so important to us? Here’s why:

Durability and longevity

Architectural spray painting is an effective way to refurbish a building as it covers large areas quicker and smoother than it would with a brush or roller. However, if it is not applied correctly, it can have adverse effects, such as orange peeling, drips and runs, poor adhesion and uneven coverage. This is why it is important to contract a highly skilled specialist and avoid spending more time and money when it’s not done properly.

Ensuring that the paint adheres well to the surface helps to maintain its appearance and protective qualities over time. This reduces the need for frequent repainting, which is both time-consuming and costly.

Weather resistant

Architectural structures are exposed to various environmental conditions, including UV radiation, rain, wind and temperate fluctuations. The fine mist of spray paint allows for better adhesion to surfaces and leaves your exterior with a flawless finish that’s both visually appealing and protective. High-quality adhesion helps the paint withstand these elements without peeling, cracking or fading.


Long-term adhesion ensures the building maintains its intended appearance over time. This is particularly important for preserving the visual appeal of commercial properties and public buildings.

Case study snapshot: Altrincham Business Park

We recently worked on a project at Altrincham Business Park, where we completed category A and B refurbishments. When we first got to the site, the entrance was outdated and in need of an upgrade. Our team carried out extensive preparation techniques before commencing spraying, and it now has a refreshed appearance that will last for years.


Achieving long-term adhesion in architectural spray painting contributes to more sustainable building practices. When paint adheres properly to surfaces, it reduces the need for frequent repainting, which in turn reduces paint waste and the associated environmental impact.

Likewise, the application of durable roof coatings and wall cladding with adhesive properties can extend the life of these building components. By protecting roofs and walls from the elements and wear and tear, long-term adhesion helps to preserve the overall integrity and longevity of the building. This not only saves on maintenance and repair costs but also reduces the need for premature replacement, further contributing to sustainability.
