If you’re wondering how to polish concrete, Glossy Floors has created (And will continue to update) a comprehensive concrete polishing guide so you can better understand what it takes to polish concrete floors.
While the step-by-step process for polishing concrete will vary with each company, the overall concrete polishing process is the same.
Concrete that hasn’t been polished will often have a topical coating (Epoxy for instance) or adhesive (Carpet, black mastic, adhesive, etc.) present that will need to be removed using a mechanical floor prep machine that uses metal abrasive diamonds. If the aggregate in the concrete is to be exposed, the burnish that exists from the original pour will need to be removed as well. Yes, this is how to polish concrete. It’s a little harder than most people realize.
There are many different types of polished concrete finishes, but we will focus on the main (Most widely used) polishing process in this article. The polishing process includes five specific steps.
Before the concrete polishing process begins, Glossy Floors will conduct a floor hardness test to determine which diamond tooling we should start with. In learning how to polish concrete, this is an important step that shouldn’t be overlooked. Once the proper tooling has been determined, we begin the concrete polishing process by placing the appropriate diamond tooling on our grinder.
If any concrete repairs are needed, this is the best time to get it completed. Holes are filled and ground down level, tack strip holes fro carpet are filled and ground level with the existing concrete, cracks are managed, etc.
If there is an epoxy or glue on the floor, the process becomes a little more involved, but for the sake of this article, the first step of the concrete polishing process involves grinding the concrete with one of the following grits: 6 ~ 16 ~ 25 ~ 40 ~ 80 ~ 150.
Depending on how hard the concrete is, we will choose diamonds that are Extra Soft (for extremely hard concrete), Soft (for hard concrete), Medium or Hard (for concrete that’s a little softer).
No matter which diamond Glossy Floors starts with, we always end using our 150 metal diamonds. It’s the last of the metal diamonds.
After we complete the initial grinding process using our metal diamonds, we use a 50 grit transitional diamond pad. This pad helps in the transition between the metal diamonds and the resin diamonds.
Once the transitional diamonds are completed, we begin using either our 50 or 100 grit resin pads and continue using the 200 grit.
Apply Stains and Densifier
If applying stains, we apply them after we complete the 200 grit resin step. This is how to polish concrete.
After removing a thin layer of concrete, the concrete itself becomes weak and soft. Applying a concrete densifier will help harden the concrete once again. After the stain has dried (If using concrete stain) we apply the concrete densifier, keeping the slab wet anywhere from 20-30 minutes. Sometimes a second coat of concrete densifier is used. While this is how to polish concrete, everyone does it slightly different.
Honing The Concrete
After our concrete stain and densifier has completely dried, (It’s important for the concrete to be completely dry!) we continue the concrete polishing process using our 400 grit diamond pads. It’s usually during this step of the concrete polishing process that you will begin to see a glossy floor. When learning how to polish concrete, this is trial and error.
Polishing The Concrete
Once we complete the 400 grit process, we continue and finish the polishing process using the remainder of our resin grit diamond pads which are 800, 1,500 and 3,000.
The final 2 steps are completely optional. Depending on the amount of gloss our customer wants, we can stop after 800, 1,500 or go all the way to 3,000. If our customer decides to continue through the 3,000 grit resin, the concrete will have a mirror like finish that resembles the look of glass. This is how to polish concrete!
We end the concrete polishing process with polishing pads. This will give the concrete its ultimate shine.
Summing It Up
- Complete hardness test.
- Repair any cracks and holes.
- Grind the concrete using 16/20 ~ 30/40 ~ 60/80 or 120/140 grit diamonds.
- Complete the grinding process using 50 ~ 100 and 200 grit resin pads.
- Apply stains and densifiers.
- Continue polishing with 400 ~ 800 ~ 1,500 and 3,000 grit resin pads.
- Complete the concrete polishing process using polishing pads. This is how to polish concrete.
That’s the basic step by step process for polishing concrete floors. If the steps outlined above are followed, you should end up with the perfect polished concrete floor. This is how to polish concrete the Glossy Floors way.
