How Much Does It Cost to Epoxy a 1,000 Square Foot Floor?
Epoxy on a 1,000 square foot floor in San Diego runs $7,000 to $14,000 installed, or about $7 to $14 per square foot. A basic solid-color garage coating sits at the low end. A metallic system with full diamond grinding, crack repair, and a UV-stable topcoat sits at the high end.

We poured a 1,050 square foot garage and shop floor in Escondido this spring. The number landed near $11,000. That job is a good middle example, so here is where the money actually goes.
What drives the price up or down?
Three things move the cost more than anything else: surface prep, the coating system, and the condition of the slab underneath.
Prep is the part homeowners underestimate. We diamond grind every floor to open the concrete pores. A floor that has been grinder-prepped holds the coating for years. A floor that someone acid-etched in a weekend tends to peel, and we have torn out plenty of those.
Solid color vs metallic epoxy
| System | Per sq ft installed | 1,000 sq ft total |
|---|---|---|
| Solid color epoxy with topcoat | $7 to $9 | $7,000 to $9,000 |
| Flake / chip broadcast | $8 to $11 | $8,000 to $11,000 |
| Metallic epoxy | $10 to $14 | $10,000 to $14,000 |
Metallic costs more because of the artistry and the material. We pour 100 percent solids resin at 60 to 80 mils and work the pigment wet, so there is no second chance once it starts to kick.
What about cracks and moisture?
Older slabs in places like Valley Center and Ramona move with the soil. We chase and fill cracks with a polyurea before any coating goes down, which adds a few hundred dollars on a typical garage.
Moisture is the other one. San Diego slabs near the coast can push vapor up through the concrete, and that vapor will blister an epoxy floor from below. We run a calcium chloride or RH test first. If the readings are high, we add a moisture-mitigation primer, and that can add $1.50 to $2.50 per square foot.
How long does the job take?
A 1,000 square foot floor is usually three days on site for us. Day one is grind and repair. Day two is base coat. Day three is the metallic pour or flake broadcast plus the topcoat. Then it needs about 24 hours before you walk on it and roughly five days before you park a car.
And that cure window matters in summer. We push pours to early morning when the slab is cool, because a hot afternoon slab in July makes the resin set faster than we want.
If you are weighing options, our metallic epoxy page covers the systems we run, and our polished concrete page is worth a look if you want a coating-free finish instead.
