Air quality is a growing concern for everyone – but particularly for those in the construction industry, where building works are responsible for 18% of the UK’s large particle pollution (as reported by The Guardian). In the built environment, however, it is indoor air pollution that is often overlooked.

According to the World Health Organisation, indoor air can be up to ten times more polluted than outdoor air. This is mainly due to the presence of volatile organic compounds, which are emitted from wall coatings, building materials, carpets, furniture and other sources.

Like other aspects of building safety, the problem of indoor air pollution needs to be tackled head-on by construction professionals from the design stage onwards. Considering the goal of most building designers is to provide a safe, usable environment for occupants, every measure that leads to better air quality must be explored.

Combating paint pollution with product innovation

Contractors, architects and building managers can all take action to reduce the impact of VOCs by making better product choices, and by forward planning. In a new building, for example, you can ensure that paintwork is completed before the space is occupied and in use.

In a currently occupied building undergoing renovation or similar works, it is often impractical to prevent access to certain rooms. It is vital you choose a paint product that tackles VOCs to protect existing occupants from pollutants, irritants and even the strong odours which some paints emit.

As a leading paint brand, Crown Trade embraces the responsibility of construction manufacturers to combat pollutants at a product level.

The NBS team spoke to Kathryn Tormay, Head of Product at Crown Trade, to learn more about their innovative developments.

Tackling VOC issues head-on

All manufacturers must reduce VOC content in their products, but Crown Trade aims to lead the way with its Clean Extreme Clean Air paint – which works to improve indoor air quality and reduce indoor pollution over time when compared to other leading durable emulsions, with only trace VOC emissions detectable (0.003 mg/m3) after 28 days.

‘Crown Trade Clean Extreme Clean Air directly addresses concerns about indoor air pollution. It not only enhances the overall aesthetic of a space but also actively improves air quality.


‘Developed by our in-house technical experts, the formula is 99% solvent free thanks to our unique air purifying technology – improving the air quality in a room from the first coat’.

In addition to lower VOCs, the formulation also works to actively absorb formaldehyde, which is one of the harmful VOCs emitted by materials such as furniture and carpets, and as a result can be more prevalent in new buildings. In fact, its air-purifying technology has been proven to reduce formaldehyde levels in indoor environments by up to 45%.

Clean Extreme Clean Air is the first Class 1 scrub-rated paint in the UK to offer these innovative properties, and also boasts BREEAM and LEED accreditations. With all of these benefits combined, Clean Air is an obvious choice for professionals who seek to improve air quality and overall sustainability in their projects.

‘Our commitment to sustainability extends beyond just indoor air quality. The packaging of Clean Extreme Clean Air is made from 100% recycled materials, ensuring that we are protecting our environment inside, as well as protecting our planet outside’.

Specialist sustainable solutions

Indoor air pollution is far from the only concern that Crown Trade aims to tackle.

The Clean Extreme range of paints is available in a Scrubbable Matt and Acrylic Eggshell finish, with specific sustainable solutions developed for specific issues (as follow).

Staining and wear

Buildings must be designed and built to last in order for them to be truly sustainable. Wall coverings therefore need to offer extended durability to limit maintenance cycles. Clean Extreme Stain Resistant provides exceptional durability and longevity, allowing for repetitive cleaning without compromising on a flawless finish.

Mould and mildew

Ideal for areas prone to moisture, Clean Extreme Mould Inhibiting paint not only resists stains but also actively prevents mould growth, making it perfect for kitchens, bathrooms and properties with higher humidity levels, including public housing developments.

Bacteria and MRSA

Clean Extreme Anti Bacterial offers a dual-purpose solution that is stain-resistant and defends against bacteria like MRSA and E. coli, so is ideal for healthcare settings.
