Grinding expertise
Surface preparation that sets up the finished floor
Concrete grinding is an effective way to smooth out existing concrete floors so they can be polished to a high gloss. We take pride in the quality of our work, whether the project is residential, commercial or industrial.
We tailor the system to each floor by considering the traffic, loads, impacts and environment it will face. Concrete Polishing Solutions provides concrete grinding in San Diego County, Orange County and Riverside County.

Grinding and polishing
Is grinding the same as polishing?
No. Grinding is usually a preparation or correction step, not a finished floor. It opens up and evens out the surface; polishing, staining, sealing or a coating then turns it into the finished floor.
What grinding does
- Removes old coatings and surface damage so the slab can be repaired and refinished
- Takes off weak surface material and foreign objects, leaving a sound surface
- Smooths a rough or uneven surface, including a rough broom finish
- Gives a coating the surface texture it needs to bond
- Can be taken deeper to expose the aggregate for a terrazzo-like look
What comes after
Polishing continues where grinding leaves off. Progressively finer diamond tooling and a densifier refine the surface until it reaches the sheen you chose. See concrete polishing.
For a coated floor, the ground surface is ready for an epoxy system or an overlay.
Advantages
Advantages of concrete grinding
Better surface texture
Grinding creates a new, even surface with the texture your finished floor needs.
A more resistant floor
Removing weak surface material and foreign objects leaves a sound surface ready for polishing or coating.
Safer work
A professional, well-equipped crew handles the grinding, with dust extraction equipment on the job.
Before and during grinding
What is checked first, and how the work is done
What a floor needs from grinding depends on what is on it now, its condition and the finish that comes next. Those are looked at before the grinders go down.
What is checked first
- Existing coatings, sealers, wax or adhesive on the surface
- Cracks, holes and joints that will need repair
- How rough or uneven the surface is
- The finish planned next: polishing, staining, a coating or an overlay
Grinding does not fill cracks; those are repaired as a separate step. See concrete repair.
How the work is done
We use a wet grinding approach, which avoids the excessive dust that dry grinding can create. Walls and surrounding areas are protected first, industrial walk-behind grinders flatten the slab, and industrial vacuums pick up the slurry.

Concrete grinding questions
Can grinding remove an old coating before a new floor goes in?
Yes. Grinding removes old coatings and surface damage so the existing slab can be repaired and refinished. Existing sealers and wax are also removed so a stain or coating can take.
Is concrete grinding dusty?
We use a wet grinding approach, which avoids the excessive dust that dry grinding can create, and industrial vacuums pick up the slurry. Dust extraction equipment is used on the job.
Is grinding always the preparation method?
In most cases, grinding the concrete surface is the usual preparation. Shot-blasting is another mechanical method, usually used for heavier epoxy mortars and urethane cement systems. The method depends on the slab and the system that follows.
Can grinding expose the stones in the concrete?
Yes. Concrete can be ground deeper to expose the aggregate, which gives a polished floor a terrazzo-like look.
