ABSTRACT
The brief for major infrastructural and building projects often includes the requirement that the surface finish should be of a high standard. There is an implication, particularly on public works projects, that the surface should remain visually attractive over a prolonged life with little or no expectation of costly maintenance. Such structures and buildings should, at the very least, grow old gracefully. A common public perception of concrete as something to be taken for granted rather than valued, can quickly lead to a perception that any new building with a concrete façade is to be tolerated rather than admired. Worse still, if the façade loses its uniformity of appearance through weathering or efflorescence any prejudice against concrete is reinforced.
