Is it better to use water for polishing?

CLC-cutting-wet-01YES! It is better to use water to polish concrete – for a number of reasons:

1. Using water lubricates the cutting surface and reduces friction & heat of the diamond pads. Less heat allows a more thorough and consistent scratch. It also means that previous scratches can be removed more quickly and completely than if done dry.

2. Cutting wet creates a savings in time and labor. Because the tools can cut more consistently, they are able to do a more thorough processing of the surface, which means less steps when done wet. Less steps means less time, and ultimately, less money for labor.


How much should my resins be costing me?

Between $.024 - $.04 USD per SF ($.26 - $.43 USD per M2).

The range of pricing is going to be determined by which "resins" you are referring to. Two types of pads are used in the industry: hybrid and polishing.

  • Hybrid Tools are for transitioning from a metal scratch
  • Polishing Tools are for removing scratches made by hybrid and producing the high polish

Hybrid Tools

resin pad hybrid toolHybrid Tools are usually made of compounds that cut a bit more like a metal tool but leave a smoother scratch pattern. You can tell a hybrid apart from a polishing pad because they are generally 6-8mm (1/4"-3/8") in thickness, rigid, and have grits of 50 to 200. A good quality hybrid comparable to what STI makes will yield 15,000-20,000 SF (1,400-1850 M2). 


When is it a good idea to use a guard on polished concrete?

grocery floorA topical sealer for polished concrete, usually called a "guard," should be used when the performance of polished concrete cannot withstand the expected chemical attack during the floor's intended use.

When acidic or stain-causing liquids are expected to be spilled onto polished concrete, using a guard product protects against these spills doing damage to the polished concrete shine or causing any discoloration. Liquids like soda, oil, wine, urine, ketchup, etc. can all damage a polished concrete floor due to the acidic property of the liquids.

The guard protects against any reaction between the acids and the polished concrete because the guard forms a micro layer of sealer. This sealer prevents any reaction between the acid and polished concrete for a period of time that is greater than if no guard were used at all. If the acid that has been spilled is not cleaned for more than manufacturer specified time (dwell and resistance times vary by manufacturer) then a stain or reaction may still occur.
