To celebrate its 125th anniversary, Keim has been running a competition in conjunction with The Architects' Journal. Entries to the 'Streets of Colour' award, launched to offer architects the opportunity to devise a colour scheme and revitalise an area or building of their choice, will be displayed on Keim's stand. The winning proposal will be implemented by the local authority or property owner, using Keim materials, as part of the company's initiative to improve the urban landscape. Keim paints comprise a potassium-silicate binder with inorganic mineral fillers and natural earth-oxide colour pigments. The paint forms a chemical micro-crystalline bond with the substrate becoming an integral part of the surface. This ensures a long-life protective finish, eliminating the need for regular redecoration.
