Located on the heritage-listed site of the former West Olympia Theatre and the legendary Grand Pacific Blue Room at 1-11 Oxford Street, 25Hours Hotel Olympia is a celebration of the art of storytelling.

KEIM became part of the story as the chosen exterior coating system for the 25hours Hotel. The façade features a complete KEIM system, combining KEIM Universal Render with KEIM Soldalit Exterior Paint.

The team behind Hotel Olympia were specifically seeking a fine render finish and a single supplier that could deliver a fully compatible system — render and paint — that was breathable, durable in Australian conditions, and supported by a long-term warranty. KEIM stood out as the natural choice.

KEIM proudly stands by its 25 Year Warranty for the 25Hours Hotel Olympia.

KEIM Universal Render is formulated with hydrated lime, pozzolanic additives, sand, and mineral fibre fillers, this ready-to-use render combines flexibility with durability. It’s designed to move with the building, accommodating thermal expansion and contraction while preventing surface crazing or cracking.

For architects, contractors, and asset owners, KEIM Universal Render provides a versatile system that performs beautifully across a range of conditions.

KEIM Soldalit is a high-performance mineral paint, free from solvents and plasticisers, delivering an exceptionally durable and clean finish.

Its unique sol-silicate hybrid formula outperforms conventional acrylic and elastomeric coatings, offering superior longevity, colour stability, and weather resistance.

Designed for a wide range of mineral and previously painted masonry surfaces, Soldalit forms a permanent chemical bond without the need for a primer in many cases, while maintaining the substrate’s natural breathability.
