Is Polished Concrete the Right Choice for Your Home?
The sleek elegance of polished concrete make it a highly desirable finish for contemporary flooring. But if you’re considering it for your home or business, you’ve probably got a lot of practical questions. How exactly is it installed? Is it difficult to maintain? And is it right for your home? Our guide to polished concrete floors has been written by our installers to answer your questions.
At DirectStone, we have been creating unique, hand-finished floors for over 20 years. In that time, our experience has taught us that when it comes to polished concrete, practical knowledge of the material is essential to a long-lasting floor.
In this guide, we’re spilling the beans on everything you need to know, from the initial installation process and the different finishes available, to the simple steps required to keep your floor looking stunning for decades.
From Industrial Strength to Residential Beauty
Polished concrete flooring typically starts life as the standard industrial concrete you might see used for a garage floor. But through a process of diamond grinding and honing – similar to how a carpenter sands fine wood to reveal the grain—we transform it into elegant, shimmering flooring.
The result is a floor that retains the toughness of its industrial roots but emanates the warmth and character of natural stone. Because every concrete mix varies, your floor will have its own unique personality and patterning.
Living with Polished Concrete – Durability Meets Comfort
There is a misconception that polished concrete is cold and unforgiving in a home. In reality, it is a fantastic conductor of heat. When paired with underfloor heating systems, the floor becomes a large radiator, holding warmth efficiently.
It is also incredibly tough. A DirectStone floor is designed to last a lifetime, handling the scuffs of shoes, pets, furniture and daily life with ease. It is a low-maintenance solution that frees you from the worry of scratching delicate wood or staining carpet.
How We Install Your Floor
We can install polished concrete flooring in many different kinds of properties. We always carry out a site visit before retrofitting a floor in an older property, to ensure we can meet your expectations.
- For New Extensions and Builds – The process begins before the concrete is even poured. We advise on the mix design to ensure the best possible finish. Once poured, the concrete must “cure” and harden fully before our diamond grinding machines can begin the transformation.
- For Existing Homes – If you are renovating, you don’t always need a new slab. We can assess your current subfloor to see if it can be restored and polished. Alternatively, we can use specialist polished concrete overlays. These are thin, self-levelling layers that offer the authentic concrete aesthetic but can be laid over existing substrates.
Defining Your Style – Your Finish Options
The “look” of polished concrete can be matched to your interior design vision. We offer four grades of finish to suit your interior design:
- Bronze – The “authentic” choice. We polish the top layer (the cream) only. It looks cloudy and organic, often with natural variations in colour. We have used this finish in a number of barn conversions.
- Silver – The “industrial” choice. We grind the top off to reveal the stones (aggregate) inside the concrete but keep the polish level low (matte). This is ideal for a raw, architectural vibe.
- Gold – The “classic” choice. Like Silver, we expose the aggregate, but we continue polishing to a smooth, shimmering sheen. It feels sleek underfoot and is very easy to wipe clean.
- Platinum – The “showroom” choice. This involves the deepest grind and the highest polish. The result is a floor that sparkles, with the aggregate clearly visible beneath a high-gloss, reflective surface.
Is Polished Concrete Right for Your Project?
At DirectStone, we believe in being completely transparent about our materials. We want you to love your floor for decades, which means understanding exactly what you are commissioning.
Structural Considerations
Polished concrete needs a stable base. It is ideally suited for ground floors where a new slab can be poured. If you are renovating a property with a suspended timber floor, the movement in the wood can cause rigid concrete to crack. In these cases, we can advise whether the floor can be reinforced or if a more flexible alternative, such as Microcement, is the better engineering choice.
Managing Expectations
There is no such thing as a “perfect” concrete floor, and that is its beauty. Unlike factory-made tiles, concrete is organic.
- Cracking – All concrete shrinks. While we place control joints strategically to guide where cracks happen, random hairline cracks can occur. This is normal.
- Staining – While durable, concrete behaves like natural stone (e.g., marble). It needs to be sealed and treated with care when it comes to acidic spills.
- Consistency -The distribution of stones (aggregate) is determined by the pour, not the polisher. Some areas may have more stone visible than others. This randomness is the hallmark of a genuine polished concrete floor.
Best Suited For
We will always advise on the suitability of polished concrete, and particular finishes, for specific areas in your home:
- Open Plan Living – The seamless nature of concrete (with no grout lines) makes spaces feel larger and flows beautifully from indoors to outdoors.
- Kitchens – It is incredibly hard-wearing. Just a reminder, though, that concrete is porous. While we seal every polished concrete kitchen floor to a high standard, spills from acidic liquids (like lemon juice, wine, or vinegar) must be wiped up quickly to prevent etching.
- Bathrooms – Concrete looks stunning in bathrooms, and it’s a flooring with good slip resistance. For wet rooms, however, we would recommend a Silver or visually textured finish – rather than a high gloss finish – to provide better grip.
Living with Polished Concrete Flooring – A Guide to Care
The longevity of a polished concrete finish comes down to (very) simple habits. It is an incredibly robust surface, but it is not indestructible. Here is our checklist for keeping your floor in showroom condition.
The “Do’s”
- DO use a pH-Neutral Cleaner – Avoid bleach, ammonia, or citrus-based cleaners. Warm water and a pH-neutral solution are all you need.
- DO use Entrance Mats – The biggest enemy of a polished floor is grit. Door mats at external doors will catch the dirt before it scratches your floor.
- DO use Felt Pads – Stick protective felt pads to the bottom of heavy furniture, tables, and sofas to prevent dragging scratches.
The “Don’ts”
- DON’T leave spills – Concrete is reactive. Oil, wine, and acidic foods should be wiped up as soon as they happen.
- DON’T tape the floor – If you are decorating, don’t stick masking tape or duct tape directly to the floor. The adhesive can leave a permanent “ghost” mark that is very difficult to remove.
Maintenance – How to Age Your Floor Gracefully
A polished concrete floor is designed to evolve. Over the years, it will develop a “patina”—a rich lustre that comes from use and wear. This is part of the material’s charm. However, to ensure it ages gracefully rather than wearing out, a specific cleaning regime is required.
- Vacuum or sweep regularly to get dust and grit. Over time this leaves microscopic scratches that will dull the finish.
- Wash the floor with a microfibre mop, using a pH-neutral cleaner.
- Leave to dry.
Restoration Services
If your floor does suffer from neglect or heavy wear over the years, the good news is that it can usually be restored. Unlike tiles which must be replaced, polished concrete can be re-ground and re-sealed by our team, bringing it back to a “good as new” condition without the need for removal.
