Polished Concrete Flooring Project in Crystal Palace, SE19 – a brutalist revival!

This project took place in Crystal Palace, SE19, within a former local authority property that proudly retained its 1960s brutalist DNA. Concrete structure, uncompromising lines and a sense of honest materiality defined the space, and from the outset it was clear that any new flooring needed to respect — not erase — that character.

The client had a very clear vision. She was in the process of curating a collection of original 1960s and 1970s furniture and furnishings, including antique pieces that deserved a floor with equal presence. Rather than hiding the building’s industrial past, she wanted to celebrate it. The brief was simple but demanding: a raw, rustic, industrial polished concrete floor that felt completely at home in the era the building was born in. Now, this is still a little unusual because we have seen a big increase in sales of cork floors in this type of properties such as Granorte Traditional cork tiles.

Assessing the Existing Floor

As with many properties of this age, the existing floor was in a poor state. Layers of old flooring, adhesive residue and heavy bitumen contamination had built up over decades. Before any aesthetic work could begin, the surface needed to be taken right back to a clean, workable concrete substrate.

We began by uplifting and removing the existing floor coverings using a heavy-duty bully stripper machine, an essential tool for breaking through stubborn, tar-based adhesives common in post-war construction. This process exposed significant areas of bitumen, which required further mechanical preparation.

The floor was then scarified to fully remove remaining bitumen and contaminants, ensuring proper adhesion for subsequent layers. This stage is critical on older concrete slabs — skipping it would compromise both durability and finish.

Preparation & Levelling

Once the substrate was properly prepared, we applied P131 primer, designed to stabilise the surface and promote strong bonding. This step helps prevent future issues such as delamination or pin-holing, particularly important when working over older concrete.

We then mixed and applied a self-levelling floor screed, carefully pouring and spreading it across approximately 50 square metres of floor area. The screed created a smooth, unified base while still allowing us to maintain the natural movement and subtle imperfections needed for an industrial aesthetic.

After curing, the floor was sanded and feather-finished, refining the surface without over-processing it. This balance was crucial: the client wanted a floor that felt authentic and lived-in, not overly polished or sterile.

Finishing & Sealing

Following final sanding and a thorough clean, we sealed the floor using an ultra-tough clear polyurethane floor sealer. This product was chosen specifically for its performance characteristics and understated appearance.

The sealer provides:

• Exceptional durability and flexibility

• Chemical and abrasion resistance

• High solids content for long-term protection

• Prevention of surface dusting, essential in residential environments

Crucially, it achieved all of this without masking the character of the concrete beneath. The result was a floor that felt robust, honest and tactile — exactly what the client had envisioned.

The Final Result

The finished polished concrete floor sits beautifully within the space. Its raw, industrial texture complements the brutalist architecture while acting as a perfect backdrop for the client’s vintage 60s and 70s furniture. Subtle variations in tone and texture add depth and warmth, ensuring the floor feels inviting rather than cold.

Most importantly, the client was absolutely delighted. The floor didn’t just meet the brief — it completed the vision. What was once a tired, compromised surface is now a defining feature of the home, grounding the interior in its architectural heritage while providing a durable, modern living surface.

This Crystal Palace project is a great example of how thoughtful preparation, material knowledge and respect for a building’s history can come together to create something truly special. And if you want us to come and make a polished concrete floor for you, we are more than happy, we loved this project and for other parts of the country you can find an accredited floor fitter at The Flooring Guild.
