Trends in paints and finishes for buildings

The last decade has seen many changes in the use of coatings by the building industry. Most notable have been the development of more durable polymers for paints, and the transfer of painting of components from the site to the factory. In addition there has been a trend towards avoiding surface coatings by choosing other materials, particularly plastics. BRE has been evaluating alternative finishes and comparing their performance with site‐applied coatings in a research project which has just drawn to a close. The work has engendered a definite preference for factory application, but elimination of coatings is not universally feasible, economic, or desirable: they will remain an essential site treatment for maintaining or changing appearance and providing additional protection following deterioration.
