As we move into the summer months, the coatings and corrosion protection industry enters its busiest period of the year. Asset owners across the UK and internationally take advantage of the warmer temperatures, longer daylight hours, and generally more stable weather conditions to undertake maintenance painting programmes on critical infrastructure. From bridges and pipelines to storage tanks, marine structures, power stations, and industrial facilities, summer provides the optimum window for coating application and asset preservation activities.

While favourable weather creates opportunities for increased productivity, successful coating application is about far more than simply applying paint on a warm day. Modern protective coating systems are highly engineered products that require strict adherence to manufacturer specifications and industry standards to achieve their intended service life. This is where the ICATS (Industrial Coating Applicator Training Scheme) plays a vital role in ensuring coating applicators possess the knowledge, skills, and competency required to deliver quality work safely and efficiently.

Environmental conditions remain one of the most critical factors affecting coating performance. Applicators must continually monitor air temperature, surface temperature, relative humidity, and dew point throughout the working day. Even during summer, rapid changes in weather conditions can create circumstances where condensation forms on the steel surface. Industry best practice generally requires the substrate temperature to remain at least 3°C above the dew point temperature before surface preparation or coating application can commence. Failure to comply with these requirements can result in flash rusting, poor adhesion, blistering, and premature coating failure.

Relative humidity also plays a significant role in coating performance. Excessive humidity can adversely affect curing and drying times, while certain coating systems may be particularly sensitive to moisture contamination. Trained applicators must understand the limitations of the products they are using and be capable of interpreting environmental monitoring data accurately.

Surface preparation remains equally important. Abrasive blast cleaning operations must achieve the specified cleanliness standard and surface profile to ensure optimum coating adhesion. Operators must understand the impact of blast media selection, nozzle size, compressor performance, air cleanliness, and flow rates on productivity and coating performance. Adequate compressed air volume and pressure are essential for achieving consistent blast quality, while contaminated air systems can introduce oil or moisture that compromises the integrity of the coating system.

Health and Safety considerations become increasingly important during the summer period when workloads are at their highest. Applicators may be working in confined spaces, at height, or in areas exposed to direct sunlight and elevated temperatures. Heat stress, dehydration, fatigue, and reduced concentration can all increase the likelihood of accidents and quality defects. Proper planning, hydration, welfare arrangements, personal protective equipment, ventilation systems, and safe systems of work are therefore essential components of any successful coating project.

Quality control throughout the coating process is equally critical. Wet film thickness measurements, dry film thickness verification, environmental monitoring records, surface cleanliness checks, and coating inspection activities all contribute to ensuring the specified coating system performs as intended. Trained ICATS operatives understand not only how to apply coatings correctly but also why these quality control measures are necessary to protect valuable assets from corrosion.

As demand for maintenance painting continues to increase throughout the summer months, the importance of competent, qualified personnel cannot be overstated. ICATS provides the industry with a recognised benchmark for applicator competence, helping contractors, asset owners, and clients maintain the highest standards of workmanship, safety, and quality. By combining practical skills with an understanding of environmental controls, coating technology, surface preparation requirements, and health and safety responsibilities, ICATS-trained operatives contribute significantly to the long-term protection and reliability of critical infrastructure assets.
