FAQ

The questions people actually ask before coating a garage floor, answered properly — including the ones where the honest answer is not the one that sells a kit.

Is it a good idea to coat a garage floor?

Usually yes, and for a reason people underrate: bare concrete is porous. It absorbs oil, road salt and brake dust permanently, it dusts constantly as the surface breaks down, and it cannot really be cleaned. A coated floor is sealed, so a spill is something you wipe up rather than something you now own.

It is a bad idea in three situations, and they are worth checking before you spend anything. If the slab is pushing moisture up from below, a coating will lift off from underneath no matter how well you apply it. If the concrete is new, it needs to cure and settle first. And if the slab has structural cracks that are still moving, the coating will crack exactly where the concrete does — a coating follows the slab, it does not hold it together.

The plastic sheet test costs nothing and answers the first one in 16 hours.

What is the best material for a garage floor?

For a floor you park on, a multi-layer resin system: a penetrating primer, a pigmented body coat, a decorative layer broadcast into it, and a clear topcoat. The layers matter more than the brand. Single-coat products ask one film to bond, color, texture and resist abrasion all at once, and the job it usually fails at is bonding.

Tiles and mats are the alternative and they are genuinely easier — but they trap moisture underneath, they move, and dirt gets into the seams. They are a good answer for a rented garage and a poor one for a floor you intend to keep.

A polyaspartic garage floor system is that structure done properly: four layers, each with one job, and a topcoat that does not amber the way epoxy does.

What is the cheapest way to cover a garage floor?

Honestly: a one-part latex garage floor paint from a hardware store, at well under a hundred dollars for a two-car garage. It will look fine for a season.

What it will not survive is a hot tire. Latex and single-part epoxy paints soften under a tire that has just come off a highway, and the tire lifts the coating off the slab as it cools — hot tire pickup, and it is the single most common way a cheap garage floor fails. Then you are grinding the remains off before you can do it properly.

So the cheapest way to cover a floor and the cheapest way to have a coated floor are different questions with different answers.

Can I install this myself?

Yes, and the honest caveat is that it is not a solo job. Once the two parts are mixed, a clock starts that does not care what else you are doing — you want two people minimum and three is better, with somebody mixing, somebody spreading, and ideally somebody broadcasting flake behind them. The day itself sets out who does what.

The part that decides the outcome is not the coating, it is the grinding. Budget four to eight hours for slab preparation on a two-car garage, and give it its own day.

And if that does not sound like your weekend — buy the coatings here and hire a local installer to lay them. There is no rule that a kit has to be installed by whoever bought it, you still get the floor you chose rather than whatever a contractor buys in bulk, and you pay for labor rather than labor plus a markup on somebody else’s materials. DIY or hire it out covers what to ask for.

Do I really have to grind the concrete?

Yes. Adhesion is mechanical — the coating grips a profile ground into the surface, and there is no chemical shortcut to it. Concrete cures with a smooth, dense skin on top, and a coating applied over that skin is bonded to a layer which is itself barely attached to the slab.

Acid etching is sold as an alternative and it is not one. It dissolves the surface rather than profiling it, leaves residue that has to be neutralized and rinsed, and cannot touch a curing compound or an old sealer. Floor preparation covers what to rent and what to do with it.

Will it turn yellow?

Not with a polyaspartic topcoat, which is what ships on every ANVIL floor. Epoxy ambers under UV — that is a property of the chemistry rather than a quality problem, and it is why an epoxy-topped floor near a window or an open door goes warm and patchy over a few summers.

How much coating do I need for a two-car garage?

A typical two-car garage is 400 to 600 square feet, but measure rather than assume — bays, alcoves and a step all change it. Then buy for more than you measured: the number that matters is coverage after waste, and running out mid-floor is not recoverable, because the joint between yesterday’s coating and today’s will always show.

Our kits are sized to the square footage you enter with that overage already included, so the arithmetic is done before you buy. Measuring your garage covers the awkward shapes.

Can I do this in a cold garage?

Down to 55°F, which is well below where an epoxy stalls and stays tacky. What matters as much as the air is the slab, and the kit itself: bring the material to 60–80°F for 48 hours before you open anything, because cold material is thick and will not level, and hot material goes off in the pail before it reaches the floor.

How long before I can park on it?

Walk on it the next morning; park on it after the full cure. The number that catches people out is not the driving one, it is the recoat window — once the base coat goes down, the clear coat has to follow within a fixed period, and missing it means abrading that layer and doing it again.

What does it cost?

A complete kit for a typical two-car garage runs between two and three thousand dollars depending on square footage and finish, plus flat-rate freight anywhere in the lower 48. That is materials for a four-layer industrial system, not a bucket of floor paint, and it is roughly a third of what the same floor costs installed.

Enter your square footage for the actual number rather than a range.

What if my slab has cracks?

Static cracks get chased out and filled before coating, and they disappear. A crack that is still moving is a different problem: it will reappear through the coating, because a coating does what the concrete does. It is not carbon fibre and it will not hold a slab together.

If a crack has a height difference between its two sides, or runs the full width of the slab, send us a photograph before you order.

Can I coat over the epoxy that is already there?

Sometimes, and it depends what it is and how well it is stuck. The test is acetone on a rag: if the existing coating softens or goes tacky, it is a single-part product that has to come off entirely. If nothing happens, it may be sound enough to abrade and coat over.

Either way it needs grinding — over the top of a glossy old floor, a new coating is bonded to the old one rather than to your slab, and it can only be as good as whatever is underneath. Existing coatings explains the test.

How long does the floor last?

These are coatings specified for plants, workshops and service bays, where the floor takes forklift traffic and gets washed down. In a residential garage they are working well within themselves.

What decides the lifespan is almost never the coating. It is the preparation underneath it, and the moisture in the slab. A properly ground, dry slab is what makes the difference between a floor you forget about and one you redo.
