Project example: a 3,000 square foot warehouse aisle floor in the Wilbur Avenue industrial area — what it involves and what it costs
Epoxy Floors Craft Antioch looks at a typical warehouse job near Wilbur Avenue: a 3,000 square foot aisle in solid color epoxy with grit, cracks and sawn joints repaired first, lane striping and joint filling priced as separate lines and the work phased so the building stays in use.

The scenario
A tenant occupies a warehouse building near the river. The main aisle is a worn, patched slab with fine cracks and open control joints. Forklifts and pallet jacks run it all day, and the tenant wants a sealed, brighter floor with marked lanes.
The work is phased: half of the aisle one weekend and half the next, with racking and stock moved by the tenant. The installer checks moisture first because the building is close to the water.
The coating is a solid color epoxy with grit rather than a heavier build, because most of the aisle sees pallet jacks rather than dock traffic.
The tenant runs a small distribution business with a dozen pallet jack paths. Everything in the aisle is stock on pallets, so moving it is the real work of the job: half of the pallets go to the loading dock for the first weekend, and the other half the next.
The tenant also asks about a color. Light gray is chosen, since a light floor makes a dim warehouse brighter and shows a fluid leak at once.
What the job involves
- The tenant and the installer walk the building, marking forklift paths, racking footprints and the zones that must stay open.
- A walk-behind diamond grinder with a dust collector grinds the aisle in sections.
- Cracks are cut and filled flush and the sawn joints are cleaned out and filled with a flexible joint filler.
- Moisture is tested at a grid of spots and the readings are recorded.
- Primer and pigmented epoxy with grit are applied in two coats, one half of the aisle at a time.
- Once the coating has cured per the data sheet, lane lines are striped and the building returns to carts and forklifts.
Materials and prep
- Walk-behind diamond grinder and industrial dust collector
- Joint filler and crack repair mortar
- Primer, pigmented epoxy and aggregate
- Striping tape and line paint
What it typically costs in the Antioch area
| Solid color epoxy with grit, 3,000 square feet installed ($4–$8 per sq ft) | $12,000–$24,000 |
| Cracks, joints and spalls to repair (+$1–$2 per sq ft) | +$3,000–$6,000 |
| Line striping and zone marking | +$300–$1,200 |
| Saw-cut joint filling, about 150 linear feet | +$300–$1,200 |
| Typical total | $15,600–$32,400 (market range, not a quote) |
These are typical local ranges, not a quote or an offer; an installer prices the actual job after seeing the floor.
Add-ons often paired with this job
- Coved base, about 100 linear feet — +$800–$2,200. A coved edge is occasionally added at a wall where cleaning matters.
Why it is done this way
A warehouse slab usually has more joints than cracks. The coating is cut to follow the sawn joints so it does not bridge them, and the joint filler takes the movement.
The numbers here use the business path: a per-square-foot system rate, a slab-condition surcharge and two flat options.
One piece of the cost conversation is the size of the floor. The numbers in this example are for 3,000 square feet; at 6,000 square feet the per-square-foot rate may fall a little as setup is spread over more floor, though the calculator keeps the same rate to stay conservative.
The tenant also needs the dock door area looked at separately. The floor near the door sees tire wear and temperature swings, so that area may get a heavier build as a second line on the bid.
What would change the price
- The moisture test reads high and a primer is added.
- A dock-door area needs a heavier build.
- An old coating or mastic covers part of the floor.
- The tenant needs the building running weekdays and the phases get longer.
- The aisle is 5,000 square feet.
