Epoxy and Polyurea Garage Floor Coatings in San Diego
Your garage floor takes more abuse than any other surface in your home — oil drips, tire marks, chemical spills, heavy impacts, and constant foot and vehicle traffic. SD Concrete Pros installs professional-grade garage floor coatings that protect your concrete and transform your garage from a dingy storage space into a clean, finished room you actually want to use.
We install both epoxy and polyurea coating systems in San Diego. Each has distinct advantages depending on your budget, timeline, and how you use your garage.
Coating Systems We Install
- Polyurea/Polyaspartic Coatings: The premium option. Cures in hours (not days), 4 times stronger than epoxy, UV-stable (will not yellow), and can be installed year-round in any temperature. One-day installation — drive on it the next morning. $6 to $10 per square foot.
- 100% Solids Epoxy: The industrial standard. Extremely hard and chemical-resistant. Requires 2 to 3 days for installation and curing. Not UV-stable (yellows in sunlight, fine for enclosed garages). $4 to $7 per square foot.
- Epoxy with Polyurea Top Coat: Best of both worlds — epoxy base coat for thickness and chemical resistance, polyurea top coat for UV stability, speed, and abrasion resistance. $5 to $8 per square foot.
- Metallic Epoxy: Decorative coating with a swirling, three-dimensional metallic effect. Popular for showroom garages, man caves, and commercial showrooms. $8 to $14 per square foot.
Why Professional Coatings Beat DIY Kits
The hardware store epoxy kits that cost $75 to $150 are water-based products with less than 50 percent solids. They peel, chip, and yellow within 1 to 2 years. Our professional coatings are fundamentally different:
- Surface Preparation: We diamond-grind or shotblast your floor to create a proper bonding profile. This step alone determines whether a coating sticks or peels — and DIY kits skip it entirely.
- Product Quality: We use 100% solids epoxy or polyurea/polyaspartic products with 3 to 5 times the thickness and durability of retail products.
- Moisture Testing: San Diego’s concrete slabs often have moisture vapor transmission issues. We test your slab and apply moisture barriers when needed — something DIY kits do not account for.
- Crack Repair: We fill and repair all cracks and joints before coating so the final surface is smooth and seamless.
- Warranty: Our coatings carry a manufacturer warranty and our own workmanship guarantee. DIY kits have no installation warranty.
Our Installation Process
- Consultation: We assess your garage floor condition, test for moisture, and discuss coating options, colors, and flake styles.
- Preparation: All items removed from the garage. Floor is diamond-ground with commercial equipment to remove contaminants and create a bonding profile.
- Repair: Cracks filled with flexible polyurea crack filler. Joints repaired. Spalls patched with quick-set compounds.
- Primer/Moisture Barrier: Applied if moisture testing indicates vapor transmission issues.
- Base Coat: Epoxy or polyurea base coat rolled on at proper mil thickness.
- Flake Broadcast: Decorative vinyl chips broadcast into wet coating for texture and aesthetics. Full broadcast (100% coverage) or partial broadcast options available.
- Top Coat: Clear polyurea or polyaspartic top coat applied for UV protection, chemical resistance, and gloss.
- Cure: Polyurea systems: walk in 4 hours, drive in 24 hours. Epoxy systems: walk in 24 hours, drive in 72 hours.

Frequently Asked Questions
How long does a garage floor coating last?
Professional polyurea coatings last 15 to 20 years with normal residential use. Epoxy coatings last 10 to 15 years. Both are recoatable when the time comes.
Will hot tires peel the coating?
Not with polyurea or polyaspartic top coats. Hot tire lift is a common problem with cheap epoxy — polyurea coatings are specifically formulated to resist it.
Can you coat a new concrete floor?
New concrete must cure for a minimum of 28 days before coating. We recommend 60 days for optimal results.
Do you coat commercial and industrial floors too?
Yes. We install coatings for auto shops, warehouses, restaurants, retail stores, and industrial facilities. Commercial projects use higher-mil systems rated for forklift traffic and chemical exposure.
