Concrete is polished by grinding with successively finer grades of abrasive discs. The initial grind removes larger imperfections and can be used to grind deep enough into the aggregate of the concrete to show the colour and pattern of the stones.

Ground or polished concrete is sealed afterwards and can be slippery. The equipment may be hired in order to do it yourself but keep the following in mind: * The grinding discs can be a significant part of the expense, * The concrete may have variations through it that will only show up on grinding * There is skill involved in producing an even finish
