Every question we get asked on driveways, answered here.

In the Raleigh area, professionally installed two-car garage floors generally land in the low-to-mid four figures, with simpler solid-color jobs at the bottom of the range and metallic or heavily repaired floors above it. The biggest cost drivers are the condition of your concrete — cracks, spalling, and old coatings that need grinding off all add labor — plus the system you choose and the total square footage. Any quote worth considering is itemized and given after someone has actually looked at the slab; be skeptical of a firm price quoted sight-unseen over the phone.

Not if the concrete was prepared correctly and the right topcoat was used. Hot-tire pickup happens when a coating sits on top of the concrete instead of bonding into it — typically the result of acid etching or skipping prep altogether. Mechanically grinding the slab opens the pores so the coating keys in, and polyaspartic topcoats stay stable well past the temperature a tire reaches. It's the most common failure on budget and DIY-kit floors, so it's worth asking any installer directly how they prep and what their coating is rated for.

A properly prepped residential floor with a quality topcoat is a long-lasting improvement — many perform well for a decade or more under normal use. Heavy traffic lanes eventually show fine scratch swirl in the finish; because the wear happens in the topcoat, that layer can usually be re-coated on its own to refresh the floor without redoing the entire system. Actual lifespan depends on prep quality, the system installed, and how hard the space gets used, and warranty terms vary by installer.

A smooth, high-gloss coating can be, so texture is worth deciding on deliberately. Full-flake floors have natural texture from the flake itself. For smooth metallic or solid-color floors, a clear anti-slip aggregate can be added to the topcoat — invisible underfoot but noticeably grippier. Exterior concrete, pool decks, and wash-down areas generally call for a more aggressive grit.

A dust mop or leaf blower for grit, and occasional mopping with water or a little dish soap. No wax or polish needed, and harsh degreasers generally aren't necessary — road salt, oil, brake fluid, and most household chemicals wipe off without staining. Avoid dragging unprotected steel across the surface (jack stands and floor-jack feet are the usual culprits); a scrap of plywood under point loads prevents gouges.

Most residential garages are a quick job — often a single day on site, sometimes two when there's significant repair work. Cure time depends on the system: polyaspartic topcoats typically allow foot traffic within hours and vehicle traffic within a day or two, while traditional epoxy-only systems usually need several days before you drive on them. Humidity and temperature both affect cure, which matters in North Carolina summers. Ask for the specific return-to-service times for the system you're quoted.

Ground. Acid etching is cheaper and faster for the installer, but it leaves laitance and contamination behind, and coatings applied over etched concrete are the ones that peel. Diamond grinding removes the weak top layer, opens the pores, and profiles the slab to roughly CSP-2/3 — the surface profile most coating manufacturers require for their own warranties to remain valid. If a bid doesn't specify mechanical grinding or shot blasting, ask why.

Usually yes — most floors that get coated have some damage. Standard practice is to chase cracks open with a diamond blade and fill them with a rigid polyurea that cures fast and sands flush; pits and spalls get patched the same way. Hairline cracks can sometimes telegraph a faint line through a solid-color floor over time, which is one reason flake and metallic systems are popular — the pattern hides repairs completely. Slabs with structural movement or active water intrusion need those problems addressed before any coating goes down.

Yes — the floor has to be completely clear, including any shelving that sits on the slab. Wall-mounted storage can usually stay put. Most homeowners stage everything in the driveway under a tarp for the day and move it back once the floor is cured enough for foot traffic. If you have heavy items you can't move yourself, mention it when scheduling so it can be planned for.

Epoxy is a thick, self-leveling resin that works well as a base coat — it builds thickness and bonds hard to prepared concrete. Polyaspartic is a faster-curing, UV-stable coating that performs better as a topcoat: it resists yellowing in sunlight, handles temperature swings, and cures in hours rather than days. Many quality systems use both — epoxy or polyaspartic below for bond strength, polyaspartic on top for durability and speed. Be cautious when a company insists on "100% polyaspartic" or "100% epoxy" regardless of the job; the right build depends on the slab and how the space is used.

It matters more in North Carolina than in drier climates. Slabs in the Triangle often test high for moisture, particularly in basements and in older homes built without a vapor barrier. Coating over a slab that's pushing moisture causes bubbling and delamination months later. Good practice is a calcium-chloride or relative-humidity test before quoting, and an epoxy moisture-vapor barrier as the base coat when readings are elevated. It adds cost upfront and it's the difference between a floor that lasts and one that fails.
