When it comes to garage, driveway, and patio coatings, most homeowners focus on appearance and durability. However, there’s another crucial factor that directly impacts both safety and performance — grip. In the world of flooring and pavement coatings, this property is often measured using something called a skid number.

At Superior Garage Floors USA, we help homeowners across Phoenix, Scottsdale, Mesa, Chandler, Gilbert, and Peoria choose epoxy and concrete coatings that not only look great but also provide the right balance of traction and smoothness for safe, everyday use.

Understanding skid numbers can help you make more informed decisions about your next flooring project — especially when safety matters as much as style.

What Are Skid Numbers

A skid number, also known as a slip resistance rating, measures how much friction a surface provides when it’s wet or dry. The higher the number, the more traction the surface offers. In other words, it’s a scientific way to measure how “grippy” a floor is.

These ratings are commonly used in industrial settings, but they’re just as relevant for residential applications like garages, driveways, and pool decks.

Typical Skid Number Ranges

• Below 35: Slippery when wet; not recommended for garages or driveways.

• 35–45: Moderate traction; ideal for smooth, decorative epoxy floors in low-traffic areas.

• 45–55: Balanced grip for residential garages and patios.

• Above 55: High traction; ideal for driveways, pool decks, or commercial spaces where water or oil may be present.

The goal is to find a finish that’s safe without being too rough to clean or maintain.

Why Grip Matters in Home Safety

Arizona homeowners use their garages and outdoor spaces year-round — from parking vehicles to hosting gatherings. Smooth concrete or poorly sealed coatings can become slick, especially when exposed to water, dust, or vehicle fluids.

Epoxy coatings with the right texture or broadcast flake system increase traction, reducing the risk of slips and falls. They also protect against wear and fading, making them both practical and attractive.

Common Household Slip Hazards

• Smooth, polished concrete without traction additives.

• Moisture near garage entries or driveways during monsoon season.

• Oil, wax, or tire residue buildup over time.

• Outdoor dust and sand that create slick film layers.

Choosing a coating with the proper skid resistance keeps your family, guests, and vehicles safer throughout every season.

How Skid Numbers Are Measured

Professionals measure skid resistance using a device called a tribometer, which evaluates friction between the floor surface and a standardized rubber test pad. This produces a coefficient of friction (COF) reading that corresponds to skid numbers.

Generally, a COF of 0.5 or higher is considered safe for most residential floors. At Superior Garage Floors USA, we adjust each epoxy formula’s texture to ensure optimal grip without sacrificing appearance or cleanability.

Balancing Grip and Appearance

A high skid number is great for safety, but too much texture can make cleaning more difficult. That’s why professional installers balance aesthetics with functionality by using different aggregates or flake systems depending on your use case.

Ways to Add Grip

• Silica sand or quartz: Adds subtle traction without affecting gloss.

• Vinyl flakes: Provide visual appeal and light texture.

• Aluminum oxide: Used in heavy-duty or outdoor coatings for maximum grip.

• Resin grit additives: Blend into clear coats for smooth, controlled traction.

Each of these materials can be adjusted to meet a specific skid number range, ensuring your floor is safe and easy to maintain.

Choosing the Right Grip for Your Space

Different areas of your home may require different traction levels depending on how they’re used.

Recommended Grip Levels

• Garage floors: Moderate grip (skid number 45–55) to prevent slips from oil or water.

• Driveways: Higher traction (skid number 55+) for vehicles and rainfall.

• Patios and walkways: Balanced texture to handle foot traffic and weather.

• Pool decks: Maximum grip for safety on wet surfaces.

The right finish depends on your needs — whether you prioritize appearance, comfort, or safety.

Why Arizona Homes Benefit from Custom Grip Levels

Arizona’s hot, dry climate followed by dusty monsoon rains creates unique traction challenges. Smooth concrete can collect fine dust, while moisture from monsoon storms can make sealed surfaces slick.

By adjusting the skid resistance of your epoxy or concrete coating, you ensure reliable traction year-round, even in extreme weather conditions.
