How to Give Your Concrete Floor a Polished Finish

By | December 20, 2016

When it comes to the choice of material, concrete is regularly the go-to choice for flooring. It is just as appropriate within residential, commercial and industrial locations and for good reason. Concrete is inexpensive, highly adaptable, hard wearing, long lasting and can withstand very heavy loads and high volumes of traffic. In addition to these benefits concrete can look very beautiful. Forget the pre-conceived notions of old that concrete is grey and uninteresting. Those days are long gone. Concrete can be treated in various ways such as by colouring, staining, stamping and various other decorative methods can be applied such as engraving. One of the simplest ways to add a little aesthetic refinement to a standard concrete floor is to have it highly polished. Doing this can give it an almost translucent appearance or leave it looking wet and glossy. This can leave it appearing like marble or some such other expensive material but without the extra costs. If you have a concrete floor of your own that needs a little bit of a spruce up, then polishing is something you can actually do yourself. It’s really quite simple you just need to source the few necessary tools for the job. Here’s a quick run through of how to go about it yourself.


The amount of work you have to do at this point will vary greatly but it is very important to do it properly else you will ruin the final finish. If your flooring is newly laid you shouldn’t have too much work on your hands at this point but it’s worth checking the quality beforehand anyway. If there are any cracks or damage marks at all they will need fixing. Also if the floor has already been sealed it will need this top coating to be removed. Once you are sufficiently satisfied that the floor is blemish free and there is no sealer then you will need to clean the floor thoroughly. Do this through a combination of wet mopping and sweeping with a hard bristle brush. It is important to get all of the loose particles swept away and then once you have completed this prep work you will be able to move onto the next stage.

Concrete GrinderPolish Once…

For this step you will need to hire a concrete grinder and some abrasive discs. You will need 3 different grades of diamond disc ranging from coarse, to fine to extra fine grit. You will go over the flooring with the coarse grit disc first but it is important that this is done in a controlled manner. You need to plan the route out before so that you pass over the surface in a uniform pattern. The grinder should be moved around in circles as you pass over your chosen route and make sure that no area of floor gets missed and there is an even pass made over the whole area.

Twice, Thrice

You will basically repeat the above step next but first using the extra grit and then to finish the fine-extra grit. Ensure that you keep being as uniform as possible and don’t miss any parts of the flooring. As you increase the abrasiveness of the diamond discs you will start to notice that the flooring becomes glossier and looks progressively smoother. Take your time with this as the quality you put in here will directly dictate how good the final look will be.

Coat Floor

Coat FloorYou’re almost there now. All that is left to be done is to re-seal the floor. To ensure that all your hard work isn’t wasted you will need to apply a concrete polish which will grant the floor the protective layer it requires. This process remains exactly the same no matter what sector or property type you are working with and so commercial concrete polishing will be exactly the same as industrial and residential floor polishing. For more options or if you go awry at any point then speak with a local contractor such as Absolute Resurfacing who will be able to carry out the work for you if needs be but why not give it a go yourself? All you need now are the tools and a little bit of elbow grease.
