Concrete polishing sounds like a dry and specialised topic, but in fact, it’s the gateway to a myriad of exciting concrete design possibilities. Think about a concrete surface. Maybe a garage floor comes to mind, or the surface of a paved street. Roughly finished concrete is grey, rough and often cracked. It is not considered by most people to be a beautiful surface. However, a concrete surface that has been finished by grinding and polishing is another matter altogether.
The most straightforward polished concrete finishes simply take advantage of the material’s subtle natural beauty. A clean and smooth grey concrete surface polished and finished to perfection looks efficient and impressive. This type of floor is often used in automotive showrooms and high tech factories. However, it’s only the simplest of the many design options offered by polished concrete.
The most striking examples of polished concrete are based on exposed aggregate and/or the use of dyes and other finishes that add colour and gloss. An aggregate is a material that is embedded in the concrete itself; ordinary concrete is made from Portland cement, sand, water and aggregate. Usually, the aggregate is simply gravel or another hard, local material. When concrete is polished, the aggregate can be exposed. Of course, a stone like marble or granite can make an attractive exposed aggregate. However, more imaginative choices like metal components and coloured glass can turn a concrete floor into a work of art. Similarly, concrete dyes and colorants can mimic other materials and create pictures and patterns in the surface of the slab.
