Clay plaster contributes to indoor air quality in several ways. Firstly, it is a natural material free from harmful chemicals typically found in synthetic paints and plasters, therefore reducing the emission of volatile organic compounds (VOCs) into the air. Additionally, clay has hygroscopic properties, meaning it can absorb and release moisture from the air, helping to regulate humidity levels and prevent mould and mildew growth. Furthermore, clay plaster has been shown to act as a natural air purifier, trapping dust, allergens and odours, hence creating a healthier and more comfortable living environment.
