Upgrading your garage floor with epoxy is one of the most effective ways to enhance both the appearance and durability of the space. But before starting your project, many homeowners want to know “What is the epoxy garage floor cost?’ The answer depends on several key factors, including the size of your garage, the type of epoxy used, labor costs, and how much surface preparation is needed. In this article, we’ll break down the specific costs specific to Idaho for one-, two-, and three-car garages, and explain what influences pricing so you can budget your project with confidence.
Epoxy Garage Floor Cost
Epoxy flooring in Idaho typically runs $5-$8per square foot installed—covering both materials and labor.
Using standard garage sizes (approximately 250 square feet for a one-car, 500 square feet for a two-car, and 750 square feet for a three-car), here’s what you can expect:
- 1-car garage (approximately 250 square feet): $1,200-$1,900. Cost per square foot: $5-$7.60
- 2-car garage (approximately 500 square feet): $2,400-$3,800. Cost per square foot: $4.80-$7.60
- 3-car garage (approximately 750 square feet): $3,600-$5,700. Cost per square foot: $4.80-$7.60.
These Idaho-specific figures align nicely with national averages (professionally installed epoxy floors range from $1,530-$3210).
Cost Components to Consider
- Cost of Labor: Labor typically accounts for 33-60% of your total cost—about $1- $7 per square foot, or $50-$150 per hour. Idaho rates align with this, though rural areas lean toward the lower end of that spectrum.
- Materials
- Water-based epoxy: $2-$5 per square foot, $30-$50 per gallon
- Solvent-based: $40-$55 per gallon
- 100% solid epoxy(industrial grade): $45-$150 per gallon
- Rock/pebble systems &decorative flakes: $100-$150 per gallon
- Surface Prep & Repairs: Mandatory prep tasks include grinding, acid-etching, pressure washing, and patching cracks.
- Acid wash/etch: $50-$100 flat fee
- Grinding (rent or hire): $400/day for equipment; contractor labor adds $1-$5 per square foot or $50-$150/hour
- Patch repairs: $25-$250 depending on severity
- Topcoat & Add-Ons
- Urethane or polyaspartic topcoat: $2-$5 per square foot + labor
- Decorative flakes or quartz: approximately $0.04 per square foot or $100 per gallon
- Anti-slip additives (sand or aluminum oxide): Inexpensive but essential for safety
Equipment Overview
Here is a list of tasks and the equipment needed:
- Concrete Prep: Diamond grinder with HEPA vacuum (rental is approximately $400/day)
- Application: Squeegee, serrated roller, spiked shoes
- Safety: Respirator (especially for solvent-based), gloves, goggles
- Finishing: Urethane polyurethane sprayer/roller (for topcoat)
Diamond grinding is strongly recommended–acid etching from big-box stores often fails to properly prep the slab.
Should You Paint or Install Floors First?
Epoxy Types: Pros, Cons & Costs
Water-based epoxy
- Cost: $30-$50 per gallon, or $2-$5 per square foot
- Pros: Low VOC(volatile organic compounds), easy for DIY
- Cons: Less durable, needs recoat every 1-3 years
Solvent-based epoxy
- Cost: $40-$55 per gallon
- Pros: Better resistance to heat and chemicals
- Cons: High VOCs, requires professional-grade handling
100% Solid epoxy
- Cost: $45-$150 per gallon
- Pros: Extremely durable, long-lasting
- Cons: Highest cost, professional installation required
Decorative systems (flakes/pebbles)
- Cost: $100 + flakes/quartz
- Pros: Great aesthetics
- Cons: Labor-intensive prep, more expensive
Poyaspartic/Polyurea topcoats
- Often used as a durable topcoat over epoxy base. UV-stable, non-yellowing
Preparing Your Garage for Epoxy: A Step-by-Step Guide
- Clear everything out: Move cars, shelving, tools—clear the floor completely.
- Repair cracks and damage: Use patchers or epoxy fillers; minor jobs are $25-$250.
- Grinding: Diamond-grind the surface; essential for adhesion.
- Cleaning: Vacuum using HEPA, mop with degreaser or denatured alcohol.
- Etching(optional): Acid etch as backup; not effective alone.
- Primer coat: Apply epoxy primer (esp. Moisture barrier priming) for better grip.
- Basecoat: Apply chosen epoxy. If you want decorative flakes, broadcast them, then allow them to set.
- Topcoat: Roll on urethane/polyaspartic to seal and protect. Add grip additives here if desired.
- Cure: Typically 24-72 hours. Avoid foot and vehicle traffic until fully cured.
Epoxy Garage Floor Cost: DIY vs. Professional Installation
- DIY kits (usually water-based) cost as little as $1,80 per square foot, but often peel, yellow, or fail prematurely. Renting a grinder and prepping the area can cost around $400 per day.
- Professional rates for a solid, durable job run between $2,300 – $4000 for a 400 square foot garage.
Idaho-Specific Insights
Areas in Idaho like Boise, Meridian, Idaho Falls, Twin Falls follow the same $5-$8 per square foot installation range, making those quoted costs reliable. Labor in rural suburban Idaho may skew toward lower hourly rates, usually around $50-$100 per hour. You can expect somewhat higher costs if your slab has moisture issues or major cracks.
Recommendations for Idaho Homeowners
- Invest in proper prep. Diamond grinding + HEPA vacuum = long-lasting bond.
- Select epoxy grade based on use:
- Budget: water based (recoat every few years).
- Mid-tier: solvent-based (better durability).
- Premium: solid epoxy + polyaspartic (lasts 15+ years).
- Add topcoat with UV-resistant polyaspartic to prevent yellowing.
- Include non-slip additives unless the floor remains bone dry.
- Get 2-3 quotes from local Idaho-based contractors; ask for prep and product specifics.
- DIY only if experienced with grinding and epoxy systems–cheap kits rarely perform well long-term.
