KEIM x SB5IVE Concrete Correction Masterclass: Rethinking What’s Possible with Architectural Concrete

On 10 June, KEIM Australia hosted the SB5IVE Concrete Correction Masterclass at our Sydney showroom, bringing together architects, builders, developers and construction professionals for a practical, hands-on look at architectural concrete refinement.

Led by the SB5IVE team, the masterclass explored one of the most common challenges in contemporary construction: what happens when architectural concrete does not meet expectations?

Rather than defaulting to demolition, replacement or concealment, the session focused on intelligent correction strategies. Through live demonstrations, material mock-ups and open discussion, SB5IVE showed how existing concrete surfaces can be repaired, refined, visually enhanced and protected long term.

A Practical Approach to Concrete Correction

Architectural concrete is often specified for its honesty, permanence and material character. But in practice, the finished result can be difficult to control. Variations in colour, patching, blowholes, surface inconsistencies and construction marks can all impact the final appearance.

The masterclass demonstrated how these issues can be approached with precision and care.

Across the day, SB5IVE shared techniques for cleaning, retouching, reprofiling and refining concrete surfaces, showing how even challenging areas can be elevated into consistent, architectural-quality finishes.

The focus was not simply on repair. It was about understanding concrete as a visible design surface and treating it with the same level of detail and craftsmanship as any other architectural material.

European Expertise, Applied Locally

SB5IVE brings European experience in high-end architectural concrete finishing to the Australian market. Their approach combines technical knowledge, material sensitivity and on-site craftsmanship to help project teams achieve better outcomes from exposed concrete.

For architects and designers, this opens up new possibilities. Concrete no longer needs to be accepted as either “good enough” or replaced entirely. With the right expertise and systems, there is often a more considered pathway — one that preserves the existing material while improving its appearance, performance and longevity.

Why This Matters for Sustainable Construction

One of the key themes from the day was sustainability.

Correcting and refining existing concrete can help reduce unnecessary demolition, material waste and rework. By working with what is already there, project teams can often achieve the desired architectural result while avoiding the cost and environmental impact of replacement.

This aligns closely with KEIM’s material philosophy. Our mineral coating systems are designed to work with mineral substrates, offering breathable, durable and long-lasting surface solutions for concrete, masonry and rendered surfaces.

The masterclass showed how surface correction, mineral finishes and long-term protection can come together as part of a more intelligent approach to architectural concrete.

A Permanent Showroom Resource

The mock-ups and sample walls created during the masterclass will remain on display at the KEIM Sydney showroom, giving architects, builders, designers and clients the opportunity to see the results firsthand.

These samples provide a valuable reference point for future projects, helping teams understand what is possible when concrete correction is considered early and approached with the right expertise.

Continuing the Conversation

The KEIM x SB5IVE Concrete Correction Masterclass was a valuable day of practical demonstration, technical insight and industry discussion.

Thank you to the SB5IVE team and everyone who attended. We look forward to continuing these conversations and helping project teams explore more durable, considered and sustainable solutions for architectural concrete.
