Smart paints: how to create sustainable spaces free from bacteria

It is nothing new to talk about all the risks that external pollution and the lack of sanitation in enclosed spaces can cause to a building. Experts have been warning for years about the need to transform working spaces into more sustainable and hygienic ones. The COVID-19 crisis has forced buildings to introduce, more than ever, elements that prevent further spread of the virus in their premises.

At Colonial we have discussed many times the importance of air quality at work offices, however, the current scenario along with the research of more efficient, sustainable and safe materials and building solutions, had led many companies to develop specific products that bring new solutions to some of these issues. Interestingly enough, new technologies have turn paint, from a mere decorative element, into an agent able to adjust noise, neutralize bacteria or even regulate temperature in a room. Check out what this new generation of paints can do for your office:

Thermoregulatory paintings

The University of Liverpool has carried out a new experiment called ENERPAINT, in which they have created a specific paint that is able to insulate buildings, absorbing the heat produced during the day by radiators and even people, and liberating it afterwards when temperatures decreased, so that it is possible to turn off cauldrons and safe energy. This effect is achieved by means of some additives made of paraffines, salt hydrates and fatty acids, the so called “Phase-change materials (PCM)”, that are encapsulated in a nanometric size in order to store great quantities of thermic energy. Such a revolution not only helps taking care of the environment, but also saves maintenance costs.

Air-purifying paintings

Another European Project named AIRLITE has also used nanotechnology to develop a paint that is able to reduce pollution, bacteria, bad odors and dirt by means of a photocatalysis process. When artificial or natural daylight reflects in the chemicals within the paint and makes contact with air, a rusting reaction takes place that decompose polluted substances lodged in. Those substances will be removed from the surface later by means of water and/or rain. Nowadays, it is possible to find in the market different type of paints that are certificated against Covid-19  and that, thanks to its composition based on lime (a well-known antiseptic), as well as a high PH value 13.13, manage to disinfect areas in 24h.

Sound-proof paintings

Raising your voice to communicate with someone implies spitting to the air about 1.000 drops of suspended saliva. This is a major problem if those drops of saliva are contaminated with viruses and we are in an enclosed space. In many occasions, the same acoustic of a room force us to raise our voices to have a communication with others, this is why it is so important to find solutions to provide a good sound-proofing of buildings and public spaces. In recent years, many companies have managed different ranges of sound-proof painting products that isolate and reduce noise levels enable effective sound propagation, so that people do not have to shout or come closer to others in order to speak.
