Collision Brewery in Longmont. Here is a job that we recently did with concrete polishing, stain and two-part polyaspartic.
Below photos, the owner had an artist come in and paint the floor and then we sealed over it. Amazing work.

Hord Coplan Macht (HCM) schools always turn out great. Especially when Concrete Floor Systems polishes their concrete. LOL. Love the natural rock look around the concrete pedestal. This job was done almost 2 years ago.
How did we do this?
We came in early in the project and ground and polished the slab. We use high-quality diamonds from Pantheon Sales and Rental which are from Diamatic. They only use South Korea diamonds. We cross hatch the floor and refine the floor to full refinement.
After we get to a 200 grit we densify the floor at 200 sq ft per gallon. We work in the Diamatic Ultra-Sil and allow it to dry overnight. Best way to densify. Then we do the 400-800-1800 grits. All edges are done by hand. All door jams are done with a small tool. No halos around the walls or door jams for CFS.
We put down two very thin applications of stain protection and burnish. Then we covered the floor with EZ Cover from Pantheon Sales and Rental.
It’s simple enough when you have highly trained craftsman working for your company…. Polished concrete if done correctly will last a lifetime, but when companies cut corners, it will not hold up or look this good.
Here is another project we were called out to review after it was polished by the low bid polisher. This was polished by a company out of Colorado Springs.
Yes, we did bid this project but told our number was too high. Now we are looking to fix it and the number just went up since we have so much more work to do. Amazing. I am getting calls on a weekly basis about floors like this.
Trust me, folks…. Finding quality concrete polishers is tough. If you have one make sure to stick with them and do not let them go. The reason this business is so tough for an estimator is the GC really does not know what the polishers is doing when they are on the slab trying to polish it.
They should be able to provide you with a detailed answer. If they don’t know what DOI and Gloss Reading are, make sure to hire another polisher ASAP
The polisher should be using a heavy head pressure machine weighing at least 1,000 lbs.
There is a wide variability in diamond quality depending on what country you get your diamonds form. We tend to find that diamonds sourced from South Korea and Bulgaria tend to be of very high and consistent quality. Diamonds from China tend to be of inferior quality in our experience. As a result we won’t use diamonds from China.
An experienced polisher will know how to read the floor and move the machine at the correct pace and speed. Every concrete floor is different. A skilled polisher knows that you can’t treat every concrete floor the same as there is a large variation from slab to slab and even from pour to pour.
Unfortunately, there is no shortage of unqualified concrete polishers. Often times, these low-quality polishers come in with the lowest bids. The end result is that you get what you pay for. The work is of poor quality, and needs to be re-worked. We are called to “fix” poor quality work quite often.
They should be applying the dye twice
This is a must for a job done right
The polisher needs to densify to full rejection.
Here is the Garden of the Gods visitor center in Colorado Springs, CO that Concrete Floor Systems did for Art C Klein Construction Inc.
We did this Concrete Floor Systems polished floor back in April 2014.
They have over 1,000,000 visitors a year walk on this floor. So 4,000,000 people later here is the floor. I took my family on Easter to do a hike and took these photos on 04/01/2018.
When polished concrete is done correctly with a densifying to full rejection and full refinement you can get floors to last and last with very low maintenance.
