How to Choose the Right Thickness (Mil) for Your Garage Floor Coating?

One of the most important but often ignored aspects of garage floor coatings is their thickness, which is expressed in mils (thousandths of an inch). The proper coating thickness can significantly impact longevity, finish, and durability, whether you're shielding your garage from tire marks, oil stains, or normal wear and tear.

Selecting the ideal garage coating thickness is crucial if you reside in the Dallas–Fort Worth (DFW) region. Heavy use, Texas weather, and varying humidity can quickly deteriorate an unprotected floor.

Understanding Garage Floor Coating Thickness

A mil is equal to one-thousandth of an inch (0.001 inch). Garage floor coatings usually range from:

• 4–8 mils for thin, DIY epoxy coatings

• 10–20 mils for professional-grade coatings

• 30+ mils for industrial-strength polyurea or polyaspartic systems

The thicker the coating, the better the impact resistance and longevity. However, higher thickness also comes with increased cost, so understanding your garage’s usage is essential before deciding.

6 Tips to choose the right Thickness for Your Garage Floor Coating

1. Evaluate How You Use Your Garage

Your garage’s purpose determines how thick your coating should be:

• 🧰 Light Use: For basic vehicle storage or light foot traffic, 10–15 mils is sufficient.

• 🏍️ Moderate Use: If you also use your garage as a workshop, go for 15–25 mils.

• 🛻 Heavy-Duty Use: For commercial setups or frequent mechanical work, 30+ mils provides long-term strength.

In the DFW climate, where hot summers and cool winters can stress concrete, opting for a slightly thicker coating can prevent cracking and peeling over time.

2. Choose the Right Type of Coating

Different garage floor coating materials perform best at different thicknesses:

Epoxy Coatings

• Thickness: 8–15 mils

• Ideal for homeowners wanting an affordable, glossy finish

• Requires controlled humidity during installation—something to keep in mind for DFW’s changing weather

Polyurea & Polyaspartic Coatings

• Thickness: 20–30 mils or more

• Excellent chemical, UV, and abrasion resistance

• Great for those seeking fast curing times and a longer-lasting solution

Acrylic Sealers

• Thickness: 2–5 mils

• Used mainly for decorative or temporary finishes

• Not suited for heavy vehicles or equipment

3. Inspect Your Concrete Condition

The condition of your existing concrete affects how thick your coating should be:

• Smooth, new concrete: Thinner systems (10–15 mils) work well

• Rough or pitted surfaces: Thicker coatings (25–40 mils) help fill imperfections

• Cracked or damaged floors: Multi-layer systems provide structural strength and smoothness

Proper surface preparation—like grinding or shot blasting—is essential for any coating to bond effectively.

4. Cost vs. Thickness in DFW

The concrete floor coatings price in DFW depends on the type, thickness, and installer quality. Average estimates:

• Epoxy Coatings: $4–$6 per sq. ft.

• Polyurea/Polyaspartic Systems: $6–$10 per sq. ft.

While thicker coatings may seem more expensive initially, they offer better long-term performance and lower maintenance costs—a smart investment for homeowners wanting reliable, lasting protection.

5. Don’t Skip the Topcoat

Even with the right thickness, a durable topcoat is vital for maximum protection.A polyaspartic clear coat (4–6 mils) adds gloss and shields your garage from UV damage, chemicals, and scratches, keeping it looking new for years.

6. Hire Local Experts in DFW

When choosing a garage floor coating in DFW, local experience matters. Professionals familiar with Texas’s temperature swings and concrete conditions will recommend the right product thickness and type for your space.

You can find reliable contractors through HomeAdvisor or other regional directories that list certified garage floor installers in DFW.
