Sydney Opera House

The Sydney Opera House is one of the world’s most recognisable architectural masterpieces and a UNESCO World Heritage-listed site. Since its completion in 1973, the Opera House has stood as a global symbol of creativity, innovation, and Australian culture. Its iconic concrete forms and sail-like shells demand not only aesthetic preservation but also long-term durability in a harsh coastal environment.

In line with the Opera House’s commitment to sustainability and heritage conservation, KEIM Concretal-Lasur was selected as the mineral coating solution to rejuvenate, protect, and harmonise the exposed concrete surfaces without altering the character of the architecture.

The Sydney Opera House project demonstrates how KEIM Concretal-Lasur can provide a balance between modern conservation requirements and respect for architectural heritage. By delivering both protection and aesthetic enhancement, KEIM helped ensure that one of the world’s greatest landmarks continues to stand as a symbol of Australian identity for generations to come.

During the refurbishment of the western foyers at the Sydney Opera House, the need arose for a suitable coating for the application onto concrete column and walls. The brief for the coating was as follows:

A coating that matched the colour of the existing concrete that would provide a homogenous appearance to the surface, evening out some of the more noticeable blemishes of the concrete whilst maintaining the natural appearance of the concrete.
