ABSTRACT:
The present invention provides a water-based lime dispersion paint comprising a binder, a pulverulent, and one or more adjuvants. The binder comprises a film-forming copolymer of an alkyl acrylate monomer and a nonionic ethylenic monomer. The copolymer is dispersed in an aqueous medium and the dispersion is stable at a basic pH. The nonionic ethylenic monomer is capable of forming a homopolymer having a glass transition temperature in the range of 70.degree. C. to 170.degree. C. The pulverulent material comprises one or more pigments and airy slaked lime having a low hydraulicity index. The adjuvants are stable at a basic pH and include D-sorbitol as a stabilizer.
