Concrete Polishing London

Looking for Concrete Polishing in London?

The concrete polished floor has gone through quite a transformation over the past couple of decades. It started out in the warehouses and factories of the industrial sector, was adopted by the offices and shopping centres of the commercial sector, and is now the flooring material of choice for high end domestic spaces currently being developed across London. Polished concrete is, without doubt, the contemporary superstar of flooring finishes, and designers find new uses for it every day.

Polished Concrete – Perfect for the 21st Century

The rapid development of grinding and polishing machines has enhanced the high gloss finish of the polished concrete floor. Its combination of utilitarian origins, made beautiful by the application of diamond studded concrete polishing pads, gives it a contemporary urban elegance which fits the mood of our time.

Polished concrete flooring also fits the 21st century bill by being both durable and environmentally friendly. Whilst carpet or vinyl needs chemical cleaning agents and regular replacements, a concrete floor will last for a lifetime – if well maintained – and it’s easy to keep clean.

The Process of Concrete Polishing in London

The specialist concrete polishers at DirectStone use HTC Superfloor™ to turn a concrete slab into an extremely strong and hard-wearing flooring that has been polished to your desired finish. How do we do it? First, we remove up to 3mm of the surface of the concrete to reveal as much or little of the aggregate in the concrete beneath as required. Then it’s hardened and sealed before being using diamond concrete polishing pads to arrive at a matt or high gloss finish.

Polishing Existing Concrete Slabs

We often get asked if an existing concrete floor can be ground and polished to a high quality finish. There’s no simple answer to this as there are so many variations. There are, however, 3 conditions that have to be met for concrete to be suitable for polishing:

  1. Density – in order to achieve a high quality polish, the concrete slab needs to be a strong mix of aggregate, sand, cement and water.
  2. Non-Tamped – tamped concrete is ridged to enhance its strength, but this finish makes it unsuitable for polishing. Ideally the concrete has been Bull or Power floated as this compacts the concrete and provides a level surface.
  3. Non-Screed – a traditional screed mix of 4:1 sand to cement cannot be polished.

If your existing concrete slab is not suitable for polishing, we can install a 10-12mm topping over an existing slab which can then be polished.

Repairing and Maintaining Concrete Polished Flooring

Your polished concrete floor needs only regular sweeping and mopping with light soap detergent to keep it looking good as new. Combined with the HTC Twister system your concrete will look good for years. It is, however, a porous material which requires re-sealing every 2-5 years. Regular maintenance will keep your floor looking good, sealed effectively, and resistant to stains and scuffing.

No matter how tired, or chipped your concrete floor may look, the experienced DirectStone repair team will be able to apply repairs, remove stains and re-polish – where necessary – to bring back its ‘just polished’ gleam.
