Sydney Concrete Polishers uses concrete floor grinding for smoothing concrete surfaces that have become rough and most commonly used to bring two un level surfaces back to the same height, thus avoiding trip hazards – which leaves a smooth surface to lay the flooring on. That can also be used to roughen up an old covering, such as paint, to improve the adhesion for the next coat of paint. Regardless of the intended final result of the floor, there are huge benefits of using floor grinding as part of the process.
