The Cost of Polished Concrete

The Cost of Polished Concrete

Topics: Polished Concrete

Polished concrete floors have become very popular in the last few years. One of the main reasons these floors have seen extraordinary growth is the long-term durability of the finished surface. Concrete is the most widely used building material for its strength and longevity.  In the past concrete had been covered by another flooring material, coated with a thick sealer or left un-treated. When left un-treated concrete can stain easily, will dust, and will be difficult to clean.

A fully polished concrete floor consists of making progressive passes with diamond abrasives to refine the surface of the cement, use of a reactive concrete densifier, and a final stain guard product.

This full polishing process for an older concrete slab might consist of the following steps

  • 40 grit – metal bond pass
  • 80 grit – metal bond pass
  • 150 grit – metal bond pass
  • 100 grit – hybrid metal/resin pass
  • 200 grit – resin bond pass
  • 400 grit – resin bond pass
  • Application of color (if applicable)
  • Application of densifier
  • 800 grit – resin bond pass
  • Application of concrete guard product

As you can see the process for this fully polished concrete floor is very extensive. This is the recommended solution for a high shine floor for retail, churches, commercial establishments, and other high foot-traffic areas. Check out projects we have completed this full polishing system on by clicking here. The multiple polishing passes create a surface that is hard to dull and easy to clean. This entire flooring solution, although great for these high-traffic environments might be out of budget for certain projects.

We have found a high-performance alternative that results in a near polished finish that works great in industrial areas, warehouses, barn floors, commercial garages, repair facilities, and agricultural applications.

This process consists of a light grinding to open the concrete surface, a double application of a reactive colloidal silica concrete densifier, and a stain protector. This floor results in a durable low-cost alternative to a fully polished concrete surface.  Unlike other concrete sealers that can peel, flake, or dust, this system conditions the existing concrete surface to create a harder and denser concrete surface for maximum durability. On new concrete this process can cost between $1.25 – $2.00 sq. ft.

My company, Dancer Concrete Design, has recently completed some projects with this sealing system around Fort Wayne, Indiana. Check out this agricultural project we completed in North Manchester, Indiana.

As always, proper preparation is key for a great finish. Here the guys run a 100 grit diamond bond pass with the concrete polisher and then auto-scrub the surface with stripping pads. This process removes surface contamination without the use of  harsh chemicals, keeps the concrete clean, and refines the surface layer of the cement floor. You can also see how the floor looks dirty and has no shine.


Here David applies the concrete densifier to the surface. This penetrating liquid reacts with the chemical makeup of cement to create a harder and denser concrete surface. This process is done 2 times with various size particulate densifiers. By using two different particulate sizes we make sure complete penetration is achieved.

The final stain guard is applied with a microfiber pad and then burnished into the surface with a high-speed propane burnisher. This burnishing action melts the surface protector into the concrete surface creating a durable shine and protective barrier.

The finished floor has a high luster and shine. This shine is not a sealer that can peel or flake but has become part of the concrete surface.  This floor can also be easily re-burnished with a stain guard if conditions would dull the surface.

In two days we made these changes to this surface. The quick cure of this system allows the floor to be open to foot traffic   upon completion and open to full traffic within 24 hours of job completion.

    Hi Nick,

    As always good article. Always good to see what the others are doing across the world and what techniques you use. Keep the articles coming!

    Quick question, how many kilo/pouds is your grinding machine?


    • nick says:

      We have a smaller machine that weighs 400lbs and our larger commercial concrete polisher is 1000 lbs.

      The weight of the machine will really have an impact on the overall polish project. We notice the more weight the better polish.

    Hi, im in love with concrete also! We live in Ireland and are building a new house. I was researching prices of polished concrete floors and the quotes I got were approx $130 per sq m!!! Crazy. We are going to try to do the work ourselves but if your in Ireland in the next 2 years be sure to let us know!!!
