The term polished concrete is a broad term that describes a mechanical process of grinding and polishing concrete. However the amount of grinding and polishing required for each project is seldom exactly the same in terms of effort and time required to complete the project. The amount of work is determined by customer's choice of texture and shine. The more aggregate the client wishes to see in the polished concrete floor, the more work is required to grind the concrete floor. There is also another important factor that sometimes is over looked and that is the hardness of the concrete. There are generally 3 categories of harness; soft, medium, and hard. As the the terms used suggest, the harder the concrete is, the longer it will take to properly grind. The softer the concrete the easier it is to grind the concrete surface. However working with too soft concrete can cause problems when attempting to expose aggregate, slowing the job down significantly.
We frequently grind and polish retail store locations of average 5,000 sf or so in size, to a fine detailed polished finish that is designed to compliment the store decor and what we call as "showroom quality polished concrete floor". A retail showroom polished concrete of this size will take an average of 6 to 8 working days to complete. However when we grind and polish concrete floor in a warehouse area say of about 20,000 sf, it can take about 6 to 9 days to complete the process. Polished concrete in the warehouse usually requires less grinding and polishing because the purpose of a polished warehouse floor serves more for practical purpose rather then esthetically, and we are able to use larger equipment which would not be suitable for "showroom quality polished concrete" to complete industrial polished concrete flooring.
As result prices for polished concrete could vary drastically from as low as $1.40 SF for large open areas, to as much as $ 8.50 SF for very detailed, hard to work with concrete floor.
