Does my concrete need grinding before a new floor goes down?
Concrete grinding and surface preparation in Pleasanton means running diamond grinders over your slab to take down high spots and strip old coatings, paint and mastic, which is the glue left from an old floor. It leaves the concrete clean and rough, so the coating or floor that goes on next can bond to it.
Most people call Artisan Epoxy Flooring of Pleasanton because they're planning something like a new garage floor coating, or because an old coating is peeling and has to come off first. We take those jobs in Pleasanton and the cities around it, at homes and commercial spaces alike. The price turns on the square footage, what's on the slab now and how thick it is, and how rough the next coating needs the concrete to be. The schedule turns mostly on testing the slab and on how much old material has to come off before the real prep starts. When I come out, I look at the slab, talk through the options and put the price in writing.
How we do concrete grinding and surface preparation
I start by asking what's going on the floor next, because the grind has to match it, and the coating maker's recommended profile decides how rough we leave the concrete. We clean off dirt, oil, grease and any curing compound, the film some slabs get when they're poured, since anything left on top can keep a coating from sticking. Then we grind by machine, with dust collection hooked up, taking down high spots and stripping old paint, epoxy or glue until we're down to sound concrete with the right texture.
A ground slab is ready for whatever comes next. If the concrete is in decent shape and you only want it protected, that's often concrete sealing. If grinding shows the surface is pitted or worn too far, concrete resurfacing and overlays put a fresh top layer over the old slab.
Light grind before a sealer or thin coat
This suits a clean slab with no old finish on it, where the next product calls for a lighter texture. We open up the surface so the sealer or coating can grab, without taking off more concrete than the job needs.
Heavy grind to strip an old coating
This suits floors with peeling epoxy, layers of paint or thick glue left from an old floor. The grinder has to cut through the old layer before it can texture the concrete, so it takes more passes than a light grind.
Concrete grinding and surface preparation in Pleasanton: permits and the floors we see
Pleasanton's Building and Safety Official issues permits when work builds, alters, repairs or demolishes a building or structure, and the city says a Planning or Zoning permit can still be needed even when a building permit isn't. Whether your grinding job needs one is the city's call, not ours, so we check with them before we start, and if a permit is needed, we take care of getting it. If you'd like to ask yourself, the city's Planning Division takes questions at pod@cityofpleasantonca.gov.
A lot of our grinding here is in garages with old paint or a worn epoxy coat, basements headed for a new floor, and shop or tenant spaces where the last floor's glue is still stuck to the slab. We see the same mix on jobs in Dublin and Livermore, and we prep those floors the same way.
Why Pleasanton property owners call Artisan Epoxy Flooring of Pleasanton for concrete grinding
I come out to every estimate
I come out to look at your slab myself, and I run the crew that does the grinding. The person who saw your floor is the one prepping it, so nothing gets lost between the estimate and the work.
Prep-first floors since 2021
We've been in business since 2021, and the floors we're best known for hold up because the slab got checked and prepped before anything went on it. If your floor or your budget points to a simpler option, I'll say so on the first visit.
Licensed and fully insured
We're licensed and fully insured, which matters when a crew is running heavy grinders in your garage or tenant space. Our work is backed by our satisfaction guarantee.
Dust collection on every grinder
California requires a dust reduction system that effectively cuts airborne dust whenever power tools grind concrete, because breathing too much of it can cause silicosis, lung cancer and other lung disease. That's why every grinder we run is hooked to a collector, and it's a fair question to put to any crew you're comparing.

Frequently asked questions
What does concrete grinding cost in California?
A medium grind of concrete in California usually costs about $3.20 to $4.50 per square foot. Where your floor lands depends on how much old coating or glue has to come off and how rough the next product needs the slab. Your written estimate gives the figure for your floor.
Is grinding or acid etching better for my concrete floor?
Grinding is usually the better choice. One coating maker's guide calls mechanical prep the first choice and the safest method, because acid is hard to rinse and neutralize, needs good ventilation and leaves oils in the concrete. Oily floors, like most garage slabs, call for mechanical prep, which is how we prep every floor.
How do I get old flooring glue off concrete?
Thick glue usually has to be ground off. Taking up an old floor often leaves mastic, adhesive or a membrane on the slab, and while shotblasting with steel shot can often clean a thin layer, the shot bounces off thick layers, so those need a grinder.
How do I know if my concrete is too wet for an epoxy floor?
You test the slab's moisture before the coating is chosen, and we do that on the floors we coat. At least one maker rules out its epoxy and urethane coatings when concrete holds too much moisture or gives off too much water vapor. Whoever you hire, ask how they check moisture first.
Will concrete grinding crack my garage floor?
Grinding is one of the gentler ways to prep concrete. One maker's guide warns that more aggressive methods like scarifying, scabbling, milling and flame blasting risk putting fine cracks in the concrete, which is part of why we prep by grinding.
Do I need a permit for concrete grinding in Pleasanton?
The city decides that, so we check with them before we start. If your job needs a permit, we take care of getting it, and you don't have to sort it out yourself.
Work that often follows the grind
Concrete Sealing
If your slab is in decent shape and you just want it protected from stains, water and wear, a sealer over freshly prepped concrete is often the simplest way to finish it.
Concrete Resurfacing & Overlays
When grinding shows the concrete itself is pitted, flaking or worn too far for a coating to hide, an overlay gives you a new top layer without tearing out the slab.
