Our concrete flooring process has 5 steps: a slab check, a written scope and price, surface prep, the coating, and a cure with a final walkthrough. Prep is the big one, because it decides roughly 80% of how long a coating lasts. We’ve used this same process for over 20 years and more than 3 million square feet, on 500-square-foot home garages and 50,000-square-foot distribution centers alike.

Why does the process matter more than the product?

Every well-known coating maker sells a product that works when it goes on right. So the bucket isn’t the big question. The big question is what happens between the day you call us and the day we leave your site.

Two contractors can put the same product on the same slab, and one floor can outlast the other by ten years. The gap is almost all prep. That’s why we’d rather walk you through the work done before the first coat goes down than brag about what’s in the bucket.

That’s also why we write our process down in detail. You should know what you’re paying for. You should also be able to lay our bid next to any other contractor’s and compare them line by line.

Step 1: What happens at the consultation and slab evaluation?

Every job starts with questions, not a price. We’ve been checking slabs for over 20 years, and that has taught us what to ask first: what you use the space for, what the floor has to stand up to, and when you need it done.

Then we check the slab itself, and we don’t do it from the doorway. We walk the whole floor and look for signs of moisture trouble:

• a slab poured before 1990
• low ground near a creek or river
• water stains
• an old coating that failed
• an age nobody knows

When we see one of those signs, we test for moisture. One test is a calcium chloride test, done per ASTM F1869, which shows how much water vapor comes up through the slab. The other is a humidity probe set down into the concrete, done per F2170. The two tests measure different things, so one can’t stand in for the other. A test adds time, because it has to sit on the slab, undisturbed, for a set period. If you’d like a test on a slab with no warning signs, just ask and we’ll run one.

We also press a replica tape onto the surface. It takes a print of the texture, which tells us how hard we’ll need to grind. Then we write down what’s already on the floor: old coatings, crack patterns, the shape the joints are in, and anything soaked into the concrete, like oil, grease, sealer, or paint.

This check decides three things: what prep your slab needs, which coatings will work on it, and how long the job will take. Without it, any price is just a guess.

Step 2: How is your project scoped and priced?

Our quote isn’t one line. It lists every piece of the job: the square footage, the prep method, the primer, the body coat, the topcoat, how many coats go in each layer, the cure time, and the schedule. It also lists how thick each coat goes on, in mils. A mil is a thousandth of an inch. A typical epoxy coat runs 8 to 12 mils, and a polyaspartic topcoat runs 4 to 6 mils. When we do test for moisture, the quote shows the F1869 and F2170 results too.

That detail lets you compare apples to apples. Say another contractor comes in lower on the same job. Lay the two scopes side by side, and you’ll see just where the gap is. Most of the time it’s in the prep: fewer grinding passes, no moisture check, or no crack repair. Or it’s in the coating: fewer coats, thinner coats, or no topcoat that holds up to sunlight (a UV-stable topcoat). Ask every bidder to put the prep in writing, including how they grind, how they fix cracks, and how deep a profile they grind to. A bottom-line number only means something once you know what it buys.

You can get a rough price in about two minutes with our online calculator. That gives you a ballpark before we come out to check the slab. The final quote comes after we’ve seen it.

Step 3: What does surface preparation involve?

Prep is the step that decides whether a floor lasts. It’s also the step a contractor cuts first when the schedule gets tight. On install day, you can’t see a rushed prep job. By year two, you can.

Good prep usually covers four jobs.

Grinding to the right profile. We use planetary diamond grinders to open up the top of the concrete. Each coating needs a certain roughness, which bids call a CSP number (concrete surface profile, on the ICRI scale). We check the slab against that scale. Get the profile wrong, and even a good coating tends to lift early, the same way paint peels off a wall nobody sanded.

Crack and joint repair. We cut out structural cracks and fill them with a moisture-blocking epoxy mortar. Then we clean out the control joints, the saw cuts in the slab. A crack we leave alone shows through the coating and turns into a weak spot where it fails.

Getting the stains out. Oil, old sealer, paint, and glue all have to come out of the concrete, not just off the top. We use degreasers, scarifiers (machines that chip the surface), or extra grinding passes, based on what we find. If grease stays down in the pores, the coating won’t stick in those spots.

Moisture mitigation. When a moisture test comes back above the coating maker’s limit, we put down a moisture vapor barrier before any coating goes on. Skipping this is one of the most common reasons we see coatings fail in this part of Oklahoma. Our clay soils and big swings between wet and dry seasons push vapor up through slabs that were never built with a barrier in mind.

Prep often takes longer than the coating does. On a rough slab, it’s also the one part we can’t fully predict until the grinder opens the surface. That’s when we see what the concrete has soaked up over the years, and what the repair will really take. A clean home garage in good shape takes a full day of prep. A 20,000-square-foot warehouse with 40 years of oil and three failed coatings takes a week, sometimes more.

Step 4: How do we put the coating down?

With the slab ready, we follow the coating maker’s data sheet to the letter. That sheet sets the pot life (how long the mixed coating stays workable), the recoat window, the temperature and humidity range, and the mils per coat.

We put the coating down with our own equipment. The same crew that checked and prepped your slab does the coating, too. That matters, because they know where the trouble spots are, where the prep took extra work, and where the slab needs a different approach.

For epoxy, we usually go on at 8 to 12 mils a coat. For a polyaspartic topcoat, it’s 4 to 6 mils. We didn’t pick those numbers out of the air. They come from the maker’s data sheet, and we check the wet coat with a gauge as we go. Thinner coats save material but wear out sooner. Thicker coats can trap solvent inside and lose their grip on the slab.

No coating, however thick, can make up for a bad pour, which is why our Pour-4-Polish framework starts with how the slab under it was poured.

Most jobs take several coats, with a set wait between them. A polyaspartic system can often take its next coat later that day. An epoxy system may need 12 to 24 hours between coats. Those windows aren’t loose suggestions. Go too early and you trap solvent. Go too late and the next coat won’t bond well to the one below it.

Step 5: What happens during the cure and the final walkthrough?

Once the last coat is down, the job still isn’t done. How long the floor has to cure depends on the system. A polyaspartic coating may take light foot traffic in 4 to 6 hours, but it needs 24 to 48 hours before you park on it. A thick epoxy system often needs 72 hours or more to cure all the way. We put these times in your scope and go over them again at the walkthrough, so you know how long to keep traffic off.

The walkthrough covers three things:

1. A look at the whole floor. We walk it with you. Any spot that doesn’t match the written scope gets fixed before we call the job done.
2. What the floor can take, and when. We go over what it can handle now and what it can handle after a full cure: when to walk on it, when to drive on it, and when it can face chemicals.
3. How to care for it. We cover which cleaners to use and which to skip, how often to clean, and what signs mean it may need a new coat someday. A well-kept epoxy floor in a home garage can last 15 to 20 years. The same floor cleaned with the wrong chemicals may show wear in five.

Can concrete floor coatings really be installed in one day?

You’ll see ads for one-day garage floor coatings. On a small, clean, dry slab with no old coating, no oil, and no moisture problem, one day can work for some products. We’ve done it ourselves. The short timeline isn’t the problem.

The problem is when one day becomes the promise no matter what shape the slab is in. A slab with moisture trouble, old coatings, oil, or big cracks can’t be prepped and coated right in eight hours. Some contractors promise that timeline before they see the slab. Then the only thing left to cut is prep time.

We take the time your slab needs. For a clean garage in good shape, that might be two days. For a commercial kitchen with decades of grease soaked into the floor, it might be five. What the slab check finds sets the schedule, not an ad.

After the job: the records we keep

We keep records of every slab check, coating system, and job condition on every project we’ve finished since 2004. Each customer gets a project summary. It lists the prep method, which shows how we ground the slab and fixed its cracks and joints. It also lists the coating system, the mil readings, the cure conditions, and a care schedule. Our slab check notes keep the rest. They show the surface profile from the replica tape, plus the cracks, joints, and old coatings we found. If you call us three years later with a care question, or you want to coat the room next door, we pull up just what we put down and match it.

For businesses with floors at several sites, those records help plan upkeep and track service at each one.

Getting started with Bel Covo

Most home garage floors run $8.55 to $10.39 a square foot, based on the shape the slab is in and the coating system you pick. Commercial prices swing wider, based on the size, how easy the space is to reach, and what the floor has to handle.
