Concrete polishing – what do I need to know?

It is not wrong to assume concrete polishing as a way to refurbish the material so as to regain its glossiness however it will be a little myopic if we assumed this is the only scene of the entire show. Concrete polishing is a highly detailed process which required many different steps that are delicately chained together so that the end-product is long lasting.

The first thing one need to know about concrete polishing is, its degree of reflectivity is a choice. Indeed, the finer the grit attached at the end of the polishing machine, the glossier the concrete. Besides shininess, one can also have a say in the colour, designs, cuts, or adding of ornaments into the concrete prior polishing. Such personalisation is common not only in household but commercial buildings, as polished concrete is known for its durability and easy to maintain.

On top of exterior, the process of concrete polishing is also subjected to one’s preference. Either dry or wet, each polishing method comes with its own pros and cons. For dry polishing, it is most preferred by industries because of its environmental friendliness and quick completion. For the latter, water is used in replacement of grit, thus friction is greatly reduced in the polishing process, enabling a long after effect. It is also getting more common for professionals to use both methods simultaneously. Normally, the dry method will be employed first to remove a thin layer of the concrete, while wet method is used later for overall beautifying.

Another thing one has to cognize is that additional chemical such as sealers will be applied during the polishing process. These sealers are not visible but are highly effective in protecting and elongating the life of concrete. Moreover, sealers also mend cracks or imperfection found in between concrete, hardening it in the course. As such, additional coating work is eliminated, greatly minimised the hassle for additional maintenance.

Concrete polishing does not start with fine grit right away, but coarse and rough cut, so as to remove any unevenness, stains, or blemishes that may not easily catch with bare eyes. Depending on the condition of the concrete, generally, this step will be repeated several times to ensure that the concrete is smooth. After which, professionals will adjust the grit, to make it finer and finer. Some diamond grit can go up to 3000, while a typical finish grit will be around 1000-1500, to give the concrete a sense of glossiness. The more experienced the crew, the more likely they can, to grasp the best time for changing of grit. Therefore, it is always advisable to consult relevant agent for concrete polishing.
