Your side of the job is mostly logistics: a garage that is empty wall to wall, a plan for the cars and the chest freezer, a decision about where children and pets will be, and an honest account of what the slab has been through. The floor itself — grinding, crack repair, moisture checks — belongs to the installer, and a few well-meant shortcuts can make that work harder. Here is the checklist we would want every Charlotte-area homeowner to have before the crew arrives.

Quick takeaways

Your prep is logistics and information: clear the space, plan for vehicles and belongings, and settle your color early.
Slab prep — grinding, crack repair, moisture assessment — belongs to the installer, so don’t pre-treat the floor.
Dust and odor are part of the job; decide where children, pets and anyone sensitive to fumes will be.
Tell the installer everything you know about what has been on the floor.
Get the return-to-traffic plan in writing and keep the cars out until you’re told the floor is ready.

What Is Your Job — and What Is the Installer's?

Your job is access, space and information; the installer’s job is the floor. A professional installation starts by mechanically preparing the concrete, usually by diamond grinding, then repairs cracks and joints, assesses the slab for moisture and masks everything that isn’t getting coated. Those steps need equipment, dust control and judgment, and they are the main reason a professional floor outlasts one that was only cleaned up by hand. Our guide on why garage floor coatings peel in Charlotte covers what happens when they’re skipped.

What the installer can’t do is decide what stays in the garage, where your vehicles and freezer go, how your family stays clear of the work, and what the slab went through before the crew arrived. One flag: if a quote hands slab preparation back to you, ask exactly what is expected and who is responsible if the coating fails over it.

How Do You Empty a Garage That Has Been Filling Up for Years?

For most homeowners this is the hardest part of the project. The crew needs the entire slab clear, including the corners and the strip along the garage door where things pile up, because a coating can’t go under a shelf. Start earlier than feels necessary and sort as you go: keep, donate, haul away, store.

Then decide where the keep pile lives. A driveway under tarps is free but at the mercy of Carolina weather. A portable storage container is convenient, but in many HOA communities it needs approval first, so check your covenants before ordering one. A spare room, a neighbor’s garage or a storage unit keeps things dry, at varying cost and inconvenience.

Empty rolling tool chests before moving them, unload shelving rather than carrying it loaded, and ask how the installer will handle fixed workbenches and cabinets — the coating has to stop somewhere, and that edge should be agreed in advance. Also ask whether the crew will move anything for you and whether that’s included or priced separately; don’t assume. If you truly can’t clear the whole garage at once, say so before the date is set: sectional work is sometimes possible, but it adds steps and can leave a visible transition if it isn’t planned carefully.

Where Do the Cars, the Freezer and Everything Else Go?

Vehicles. Every vehicle comes out for the job and the cure that follows, and you won’t have a firm return-to-traffic date until the installer has seen the garage, so plan on the longer end of what you’re told. Our guide to how long a garage floor coating takes explains what drives the timeline. Check what your HOA allows for overnight street parking in places like Waxhaw, Indian Trail and Fort Mill, and ask how much driveway the crew needs.

EV charging. If you charge at home, line up a plan B, such as a public or workplace charger. A cord across fresh coating is a problem.

Chest freezer and second fridge. They hold food, need power and can’t sit in the driveway. Line up an indoor spot with an outlet before the crew arrives, and ask how long to plan for; an honest answer comes after the site visit.

Fuel, propane and chemicals. Each carries storage guidance on its label, and none belongs in the living space or a hot car trunk. For more than a small amount, ask your local fire department what is appropriate.

What Should You Leave Alone on the Floor Before the Crew Arrives?

The instinct to “get the floor ready” is strong, but the installer’s prep method decides what helps and what gets in the way, so ask before you touch the slab. As a rule, leave these to the crew.

Pressure washing. Concrete absorbs water and releases it slowly, so a slab that looks dry on top may not be dry through. If you’ve already washed it, tell the installer when and how much.

Degreasers and cleaners. Some leave a residue the crew then has to deal with, and scrubbing doesn’t necessarily lift oil that has soaked in.

Patching cracks. Caulk or hardware-store filler may look tidy, but the installer may have to cut it out to repair the crack properly. Photograph cracks instead; our guide on garage floor cracks explains what can be repaired before coating and what can’t.

Sealers, “prep” products and DIY-kit pretreatments. Anything applied to the concrete changes what the installer is dealing with. Skip them unless your installer asks.

Scraping an old coating. If one is peeling, leave it. How it failed tells the installer something about the slab, and removal is part of their prep anyway.

What you can do: sweep loose debris, remove anything that isn’t the floor, and photograph the slab — cracks, stains, old coating, drains — before anyone touches it.

What Do Dust, Odor and Ventilation Mean for Your Family and Pets?

Preparing a slab creates dust and coating it creates odor. Both are manageable, but ask about them at the site visit rather than discovering them on the day.

Dust. Grinding is normally done with dust extraction, but no system captures everything. Don’t leave anything in the garage you’d be upset to see dusty, and ask how the crew will seal off the house entry and any vents that open into the garage.

Odor. Some systems are low-odor, others strong, and odor can travel through the entry door and the HVAC system. Ask which product will be used, what to expect and how they’ll ventilate, and ask for its safety data sheet if you want to read it.

Who should stay clear. Children, pets and anyone with a respiratory condition or chemical sensitivity are best kept elsewhere while the work is underway; pet birds are especially sensitive to fumes. The installer can tell you how long to plan for, and your doctor is the right person to ask about a medical concern.

Appliances. If a gas water heater, furnace or air handler is in the garage, mention it at the site visit. Anything that needs to be shut down, shielded or moved should be handled by the licensed professional who services it, not improvised.

What Should You Settle With the Installer Before — and on — Install Day?

Most install-day surprises could have been settled at the site visit.

What’s been on the floor. Old coatings, paint, sealers, DIY kits, oil spills, a past water problem, work by a previous owner — say what you know, and say so if you don’t. It affects both the prep and the risk of failure.

Color, flake and finish. Decide before the job is scheduled, ask when the choice must be final, and view a sample in your own garage lighting. Our guide to flake, metallic and solid color looks can help.

The edges. Where does the coating stop — at the door threshold, the entry door, around a water heater or drain? Agree on those lines in advance.

What the crew needs. Power, water, a restroom, space for materials and a clear driveway; one reachable person who can approve decisions; clear instructions for the garage door and house entry.

The return-to-traffic plan, in writing. Ask when you can walk on the floor, when light items can go back and when the cars can come in, and what would change those dates. Any date before a site visit is an estimate. Before the crew leaves, look the finished floor over with the lead installer and ask what not to do while it cures. Our guide on cleaning and maintaining an epoxy garage floor covers the long-term routine.

Frequently Asked Questions

How much of the garage has to be empty?

All of it, wherever possible. A coating can’t go under a floor-standing workbench or shelf, and anything left becomes an obstacle and a dust target. Items fixed to the walls can often stay with the coating stopping at their edges — agree on those at the site visit.

Will the crew move my belongings for me?

Don’t assume so. Some installers move a limited amount, some don’t, and it may be priced separately. Ask at the quote stage what is included and get it in writing.

Should I pressure wash the floor first?

Generally no, unless the installer asks. Their prep handles cleaning, and concrete that looks dry can still hold moisture. If you’ve already washed it, tell them when and how much.

Do I need to be home during the installation?

Someone reachable should be available to answer questions and look over the finished floor, but you needn’t be in the garage. Agree on a contact person, a phone number and garage-door and house-entry instructions beforehand.

Can my family stay in the house during the work?

Often yes, depending on the product, the ventilation plan and your home’s layout. Ask what to expect and how the entry door is sealed; children, pets and anyone with respiratory issues may be better off elsewhere.

What happens if the weather turns or I need to reschedule?

Humidity and temperature affect how coatings go on and cure, which is why timing matters — see our guide to the best time of year to coat a garage floor in Charlotte. Ask how your installer handles weather delays and rescheduling before you book, and get it in writing.
