Concrete polishing is an increasingly popular flooring choice which is defined as concrete that has been treated with a chemical densifier and ground with progressively finer grinding tools to leave a smooth, polished surface. The polished concrete floor is the next step up from honed concrete.
It is considered to be a good, sustainable design flooring option because it makes use of the materials already present. Most modern buildings are built on a concrete slab; polishing raw concrete eliminates the energy and material consumed by applying a floor covering. It is something to consider when building or renovating areas to achieve a more eco-friendly solution.
Polished concrete floors are low-maintenance, as they are more durable and easier to clean than other flooring options. Polished concrete reduces dust mite and allergen problems, anddoes not support mould growth. A concrete floor that has been hardened and polished will have an extremely long life expectancy compared to other flooring.
The result you can expect will depend on the following factors:
- The colour and hardness of the course aggregate exposed by the grinding.
- The colour of the concrete matrix. The matrix is typically matched in colour with the coarse aggregate. This is achieved through cement colour and/or the addition of pigments (oxides).
- The quality of the concrete. Regardless of what properties may be required for structural reasons, a high-strength concrete is desirable for the honing process.
- The fineness of abrasives. As indicated earlier, the fineness of abrasives used for honing, i.e. the number of stages in the honing process, will determine the smoothness and lustre (shininess) of the finished surface. To achieve a polished finish the honed surface is polished with superfine grinding pads.
- The depth of honing will determine the extent to which coarse aggregate is exposed. A light honing of the surface will typically expose the fine aggregates (sand) within the concrete mix and possibly the tops of coarse aggregate particles. Progressively deeper honing will expose more of the coarse aggregates. Where large aggregate particles are required in the finish, it may be more economical to seed the surface with an aggregate having a flatter shape, or to cast in flat pieces of stone to reduce the extent of honing required to achieve the desired polished concrete finish.
