Along with being very durable, polished concrete floors are also easier to maintain compared to other flooring options. Polished floors are non-porous, which means that liquids do not seep into the ground. This also makes dust and dirt easy to remove as well, which is very useful for school floors. Using polished concrete also means you have a floor that is able to last for a longer period of time. With proper maintenance, polished concrete floors can last for a number of years before needing to be replaced.
