Environment-friendly lime paints were prepared from 38 wt% slurries of hydrated lime (Ca(OH)(2)) and hydrated light burned dolomite (Ca(OH)(2)center dot Mg(OH)(2)). These materials and the resulting paints%26apos; antibacterial and anti-mold properties were investigated. The hydrated lime used in this study contained 97 wt% Ca(OH)(2), which implies a 71.85 wt% equivalence of CaO. This 71.85 wt% CaO content was responsible for the antibacterial and anti-mold characteristics. The antibacterial and anti-mold characteristics of the hydrated light burned dolomite were attributed to its 56 wt% CaO and 44 wt% MgO contents. The antibacterial-reducing activities of 38 wt% hydrated lime and hydrated light burned dolomite slurries were found to be 99%. Their anti-mold activities against mixed strains were outstanding. Lime paints produced from the slurries and various additives also showed 99% antibacterial activity and outstanding anti-mold activity. The paints%26apos; low total volatile organic compounds (TVOCs) releases were graded as excellent. Their formaldehyde (HCHO) releases were classed as best through excellent, indicating their suitability as environment-friendly building materials.
