Thecrystals refract light, which gives a unique aesthetic quality to thepaint-unmatched by any other. Limewash subtly refl ects the natureof the substrate and pigments move through the paint to create alively fi nish. When wet, colours will intensify and gradually lighten ondrying creating a dynamic and dramatic external fi nish.For use: Internal and external porous surfaces e.g. stone, oldlimewash, lime render, lime plaster.Coverage: 60-80sqm per litre per coat.Please call for a colour chart.Please call for a colour chart.CoursesTŷ-Mawr run and host a range of professional courses includingLime Specifi cation, Lime in Building and Lime Plastering as wellas technical days on limecrete fl oors and energy effi ciency fortraditional buildings and new build.
