Enriching our lives with colour
DAVID PRATT OF KEIM MINERAL PAINTS OFFERS A SIMPLE LONG TERM SOLUTION FOR THE USE OF COLOUR TO PROVIDE AN EXCITING AND VIBRANT APPEAL FOR EXTERNAL NEW BUILD FACADES.
C
olour is a very important factor in our lives. It is often taken for granted and under appreciated. What a sad and boring outook it would be if we lived in a grey monotone world. And paints over the centuries have been the traditional providers of the colour we need in our lives, decorating buildings from the earliest days.
Today’s architects of course, pay a great deal of attention to creating an interesting and attractive environment, designing buildings that complement their location in shape, style and colour treatments.
Self coloured renders have gained widespread acceptance in public sector and commercial sector construction as a further extension in the use of lightweight render systems to achieve quality external facades in the new build specification market. Understandably specifiers look to test the boundaries of these new products and, in particular, call for a wide variety of strong colours. They seek to use these materials in many different ways to get away from the bland and vast expanses of pastel monotone finishes.
These requirements introduce technically difficult parameters such as maintaining
strong colours during application, as well as actually in service. There is a need to break up the appearance of facades using multi- colours, highlights and feature panels to add interest and generally enhance the visual appeal and general harmony of the building.
Whilst it can be possible to achieve some of these results, it is often with high cost repercussions or the need to resort to the use of applied coating systems in addition to the self coloured renders. Even with the extra treatment coats some systems still routinely require colour equalisation paint coats to be applied to provide any guarantee of long term colour stability.
A less costly and more versatile solution - and one which is often preferred by the designer of the building - is to apply a proven thin

section render that combines with a long life mineral coating system to provide all of the design flexibility with a known performance and at a defined economic cost.
This was the preferred choice for Flintshire County Council for the design and construction of the external envelope of a £3.2 million primary school in Greenfield, Flint to cater for the increasing pupil numbers. The new school replaced an existing one which dates back to the early 1900’s and now has all necessary facilities on one site catering for up to 330 children aged from 3 to 11 who will progress through Reception, Infant and Junior classrooms.
The layout of the new school building draws its influences from the evolution of the Greenfield valley and its part in the Industrial Revolution in North East Wales.
The exterior of the building exterior features a colourful treatment using Keim Universal Render with the Keim Granital longlife masonry paint system. Although originally specified with a through colour render, the council preferred this specification as it offered a more cost effective easier to maintain solution.
