How much does epoxy flooring cost?
Step-by-Step Guide to Estimating the Cost of Epoxy flooring
The cost of epoxying a floor (approximately 400–500 sq. ft.) depends on factors such as materials, labor, and additional features like decorative flakes or coatings. Here’s how you can estimate the total cost.
1. Determine Size and Condition
A standard 2-car garage typically ranges from 400 to 500 sq. ft. If your garage has existing coatings, cracks, or oil stains, extra preparation work may increase costs.
2. Choose the Type of Epoxy Coating
There are different epoxy systems with varying costs per square foot:
Water-Based Epoxy: Costs between $3–$5 per square foot. It is budget-friendly and best for light-duty use.
Solvent-Based Epoxy: Costs between $4–$7 per square foot. It offers more durability and is suitable for moderate use.
100% Solid Epoxy: Costs between $6–$10 per square foot. This is the most durable option and provides a high-gloss finish.
Metallic Epoxy: Costs between $8–$15 per square foot. This is a decorative option that creates a unique, high-end look.
Flake Epoxy System: Costs between $6–$12 per square foot. It includes decorative flakes for added texture and slip resistance.
3. Calculate the Base Cost
For a 400 sq. ft. garage, the estimated total costs are:
Water-Based Epoxy: $1,200 – $2,000
Solvent-Based Epoxy: $1,600 – $2,800
100% Solid Epoxy: $2,400 – $4,000
Metallic Epoxy: $3,200 – $6,000
Flake Epoxy System: $2,400 – $4,800
DIY epoxy kits typically cost between $2–$5 per square foot, meaning materials alone would be between $800–$2,000, but professional installation ensures better durability.
4. Factor in Additional Costs
Some extra services may increase the price of the job:
Surface Preparation (Grinding/Etching): $1–$3 per square foot
Crack and Damage Repairs: $50–$200 per repair
Moisture Barrier Primer: $0.50–$1.50 per square foot
Topcoat for Extra Durability: $1–$3 per square foot
For example, if you add a moisture barrier and heavy grinding, costs may increase by an additional $500–$1,500.
5. Compare DIY vs. Professional Installation
DIY installation for a 400 sq. ft. garage costs between $1,000 – $2,500, while professional installation typically ranges from $1,800 – $6,000.
DIY material costs range from $800–$2,000, but you may also need to rent equipment like a floor grinder, which can cost an additional $200–$500.
DIY projects take about 2–3 days to complete, while professionals usually finish in 1–2 days.
Professionally installed epoxy lasts 10–20 years, whereas DIY applications may only last 3–5 years if not applied correctly.
Hiring a professional ensures better surface preparation, even application, and longevity, making it a better long-term investment.
6. Get Quotes and Schedule the Job
Contact local epoxy flooring contractors to get accurate quotes.
Ask about warranty coverage—most professionals offer warranties of 5–10 years.
Make sure the estimate includes surface preparation, epoxy layers, and sealing to avoid hidden fees.
