Concrete flooring is becoming popular not only in the industrial sector, but in smaller businesses, schools and even homes as well. Being able to polish concrete to the point that it has a beautiful, shiny finish is what has made many people turn to this affordable method of flooring which can rival even the most sophisticated types of flooring including granite and marble. Understanding what you are looking for and how you will use polished concrete equipment will help you make the right choice when it is time to rent or buy equipment to make your floor look brand new once again.
Before you Start
Before you start grinding concrete, you need to determine the type of finish you are looking to have on the completed project. If your end goal is to have a floor with an extremely shiny finish, you will want a concrete grinder with a higher grit, which means a smoother finish; typically the highest grit available is 3000 grits. Once you grind the floor, which might take several passes with different grit levels, it will be able to be properly polished and ready for the finishing touches. Typically up to 1/16” of the surface of your concrete floor will be removed in order to properly polish it to the desired level.
Hardening the Concrete
Once you go through one pass on the concrete floor with the grinder, you will need to use a concrete hardener to make the surface denser. This process may need to be done several times in order to reach the desired level of shininess on the concrete floor. When you are near the level that you want for your polished concrete flooring, you will switch the pads out for a less abrasive and smoother pad. This is what will give the floor the smooth, shiny look that you desire for your end product.
Once you have gone through the successive grit levels on your concrete floor polishing equipment and have the desired level of shine on your floor, you should add a sealer. This will not only add to the level of shininess on the floor, but will protect it from stains. This is especially important in high traffic areas that could be subjected to chemicals or grease that could ultimately stain the concrete, forcing you to have to do the grinding process all over again.
