What does concrete grinding do before a new floor goes down?
Concrete grinding and surface preparation in West Hollywood takes your slab down to clean, sound concrete with diamond tooling, strips off old coatings, paint or mastic, and leaves the roughness your new coating needs to grip.
Most people call us because something has to come off first, like a garage coating that's peeling, old paint, or the black adhesive left after carpet or tile came up, or because a new epoxy floor is booked and the slab has never been prepped. The price moves with the size of the floor, what's on it now and how many layers there are, and how rough the next coating needs the concrete to be. The schedule turns mostly on how stubborn the old material is and on the moisture test, which involves waiting you can't rush. I come out, look and measure, and the written estimate lists each step in order, so you'll see where the time and the money go before we start.
How we handle concrete grinding and surface preparation
First I find out what's going on the floor next, because an epoxy, a urethane and a sealer each want a different roughness, called the surface profile, and we set the grind to match it. Our crew then grinds with diamond tooling to take down high spots and strip old coating, mastic or paint until we're on sound concrete. Next comes the cleaning, and we're thorough about it because a slab ground to the right roughness still fails if it's left dusty or oily, and no amount of grinding makes up for that. Then we check moisture before anything goes down. Every prep job is backed by our satisfaction guarantee.
Grinding is often the first step of a bigger job. If the floor will stay bare, we can follow it with concrete sealing to keep stains out of the fresh surface, and if grinding shows concrete too worn or uneven to coat directly, concrete resurfacing and overlays give you a sound new top to build on.
Diamond grinding for most floors
This suits most garages, basements and shop floors, because it removes thin coatings and high spots and leaves a controlled roughness for the coating that follows. It also gets into edges and smaller rooms well.
Shot blasting for large, open slabs
Shot blasting throws steel shot at the concrete and leaves an even texture across big, open areas. It suits wide, unobstructed floors better than tight rooms with a lot of corners.
Scarifying for thick buildup
A scarifier cuts away heavy layers fast, but it can damage and loosen the top of the concrete, so one coating maker's guide requires shot blasting afterward. If a contractor plans to scarify, ask whether that second pass is in the plan.
If a coating install is already booked, call us before the installer arrives, because grinding, cleaning and moisture testing all need room on the schedule first.
What happens after you call about concrete grinding in West Hollywood?
Here's how a prep job runs with us, from your first call to a clean, tested slab, and where the city's rules on delivery hours fit into the schedule.
Call or send a message
Call or use the form and tell us a little about the floor, and we get back to you to set a time to see it. A photo of the current surface helps if you have one.
I come out and measure
I look at the slab, measure it and ask how you use the space, then we send a written estimate that lists each step in order. You'll see what's coming off, the roughness we're aiming for and the moisture test, so you know what each part of the price pays for.
We set the full schedule
Once you say yes, we build the schedule with every test and wait in it, so the coating isn't rushed onto a slab that isn't ready. In West Hollywood, deliveries and loading of equipment happen only from 8:00 AM to 7:00 PM unless an extended hours construction permit is in place, and we plan our arrival around that.
Our crew preps and cleans
Our crew grinds, cleans and tests, then does the rest of the work on the estimate and cleans up. We tell you the moisture results before anything goes on, because that's the point where the plan can change.

West Hollywood requires every city approval and permit to be in hand before any construction starts, and whether a grinding job needs one depends on the job, so I check that during the estimate, and when one is needed, we handle the application and the city's paperwork. The city also requires an encroachment permit if any part of the street, alley or public right-of-way is used for construction work, which matters on tight lots where a grinder or dust collector might end up at the curb, so we plan staging on your property where we can. You can read the city's construction rules yourself, and we're licensed and insured for this work.
Here we see a lot of condo and commercial floors with old adhesive under them and garages with tired coatings, and each fix starts the same way, with the right grind and a clean, dry slab. We're based in West Hollywood and work across the cities around it in Los Angeles County, with the same order on jobs in Beverly Hills and Culver City.
Concrete grinding questions from West Hollywood owners
How much does concrete grinding cost in West Hollywood?
Concrete grinding and surface prep across the US usually costs about $1.50 to $3.50 per square foot, and that national range covers the prep, not the coating that follows. Where your floor lands depends on its size, what has to come off and how rough the next coating needs it, and the written estimate gives you your own figure.
Does concrete need to be dry before epoxy is applied?
Yes, moisture inside the slab should drop to acceptable levels before a coating or any other flooring goes on. If it doesn't, moisture can collect underneath and cause blistering, buckling, adhesive failure or mold, so we test before we coat.
How long does concrete surface prep take before coating?
Plan for at least a day of waiting on top of the grinding, because under the standard in-slab humidity test each sensor settles for 24 hours before a reading can be recorded. How long the grinding itself takes turns on the floor's size and what has to come off, and your estimate lays the schedule out step by step.
How rough does concrete need to be for an epoxy coating?
High-build epoxy and urethane coatings are commonly specified at CSP 3 to 5 on an industry roughness scale that runs from CSP 1 to CSP 10. Thinner coatings and sealers usually want less, which is why the next coating decides the grind.
What is the best way to control dust when grinding concrete?
One coating maker's guide says grinding with diamond tools makes a lot of dust, so a capable dust collector must be used. Concrete dust holds breathable crystalline silica, a known carcinogen that can cause silicosis, an incurable and often fatal lung disease, and lung cancer, and the state's construction silica rule covers renovation work like this, so we plan dust control as part of the job.
Does a commercial property in West Hollywood need a licensed contractor for floor prep?
Yes, the city's building permits for commercial properties require a licensed contractor. We're licensed and insured, and we plan the prep and the coating together so you aren't closing twice.
Concrete work that often follows grinding
If your floor is staying bare or polished, a sealer over the freshly ground slab keeps oil and water from soaking back into the clean concrete.
When grinding shows a slab too worn, cracked or uneven to coat directly, an overlay gives you a new top layer to build the finished floor on.
