Warehouse Floor Coating in Antioch
Epoxy Floors Craft Antioch covers warehouse floor coating in Antioch — dry aisles and loading docks, forklift and pallet-jack wear, joint filling and line striping — with a plain comparison against polished concrete for buildings on the Wilbur Avenue side of town.

What a forklift does to a coating
A warehouse floor takes small, hard wheels under heavy loads, turning and braking in the same few paths. The damage shows first at turns, at dock doors and at the ends of aisles. A coating for this use is built thicker than a garage coating, with grit or quartz for traction, and its joints and cracks are repaired first so a wheel does not hammer an open edge.
The loading dock is its own problem: slab-edge moisture, temperature swings and tire wear. Many warehouses coat aisles in a plain solid epoxy and put a heavier build at the dock.
Joints, cracks and striping
Sawn control joints move with the seasons, so they are filled with a flexible joint filler and the coating is cut to follow them rather than bridging them. Cracks are cut and filled flush. Once the floor is coated, line striping marks aisles, pedestrian lanes, racking footprints and staging zones; it is applied over the cured coating and priced as a flat option, about $300–$1,200 for a typical building. Joint filling, around $300–$1,200 for about 150 linear feet, is another flat option.
Epoxy or polished concrete?
| Epoxy coating | Polished concrete | |
|---|---|---|
| What it is | A film adhered to the top of the slab | The slab itself, ground and densified |
| Prep | Grind, repair, prime | Grind in stages, densify, polish |
| Dust | Seals the surface | Reduces it, not as sealed |
| Appearance | Colors, lines, texture | Natural gray, sheen from grit stages |
| Repairs | Recoat locally | Re-polish the area |
| Where it fails | Peels from a wet or poorly ground slab | Staining by fluids, wear at turns |
| Cost band | $4–$8 per sq ft for solid epoxy with grit | Priced separately by a polishing contractor |
Polished concrete is a different trade — grind and polish, with no coating — and it suits clean, dry buildings with sound slabs. It appears here only as a comparison.
Wilbur Avenue and the industrial slabs
Antioch's heavy-industrial land sits along the San Joaquin River on Wilbur Avenue, where former mill sites and newer shells have slabs of very different ages. Buildings close to the river can have a high water table, so a moisture test (ASTM F1869 or F2170) comes before any coating, and a vapor-barrier primer, about $1–$2.50 per square foot, is added where the readings call for it.
A 3,000 square foot aisle, priced
A solid color epoxy with grit at $4–$8 per square foot, plus $1–$2 for cracks and joints, gives about $15,000–$30,000 for 3,000 square feet, before striping and joint filling. These are market estimates, not quotes.
Warehouse Floor Coating — common questions
Can forklifts drive on a new epoxy floor right away?
No. Return to carts and forklifts is set by the product's data sheet for the day's temperature and humidity; fast-cure systems shorten it. Ask for the figure for the named product.
Is polished concrete better than epoxy for a warehouse?
It depends on the slab and the traffic. Polished concrete suits clean, dry buildings with sound slabs; epoxy sealing suits floors that need color, lines or a sealed surface.
