Summer Heat and Court Surface Durability: What Every Facility Manager Should Know

Court surface durability is increasingly important as summer temperatures rise. Athletic courts—whether at schools, parks, or private facilities—are being tested by heat waves that cause fading, softening, cracking, and warping.

 

Managing these risks starts with understanding how summer heat affects surface materials, what options perform best, and how to care for courts during the hottest months of the year.

​

How Does Summer Heat Affect Court Surface Durability?

Hot weather has a direct impact on court surfaces. When temperatures climb, materials like asphalt and acrylic coatings can soften or lose flexibility. Over time, this leads to problems like cracking, peeling, surface bubbling, and color fading.

​

Thermal cycling—when the surface expands during the day and contracts at night—can also create microcracks. These cracks often go unnoticed until they expand into larger structural issues.

 

According to the American Sports Builders Association, UV radiation is a major contributor to surface degradation, weakening binders in top coatings and reducing the lifespan of both color and texture.

​

Which Court Surfaces Hold Up Best in the Heat?

Choosing the right surface is the first step in building long-lasting courts. Here’s how the most common surface types compare in hot weather:

​

1. Asphalt
Asphalt is popular due to its low cost and quick installation. However, in high heat, it becomes soft and may warp. Without proper coatings, it can reach temperatures above 150°F, making it less ideal for long-term durability.

​

2. Concrete
Concrete offers better heat resistance than asphalt. It doesn’t soften, and its thermal expansion rate is more predictable. However, without proper joints or a stable base, it can crack. Applying an acrylic coating helps protect the surface and improve play quality.

​

3. Acrylic-Coated Surfaces
Acrylic coatings are often applied over asphalt or concrete. High-quality coatings improve grip, resist fading, and protect from UV damage. However, low-grade acrylics tend to dry out and crack faster in hot climates. The thickness and UV rating of the coating matter.

​

4. Modular Tile Systems
Modular tile courts are made from interlocking plastic tiles designed to allow airflow underneath. This helps reduce surface temperature and allows movement without cracking. According to SnapSports engineer Maria Chen, these systems can be up to 20°F cooler than asphalt and offer excellent heat resilience.

​

How Do You Choose the Right Surface Materials for Hot Weather?

When deciding on materials, consider your location’s climate, how often the court will be used, and how much time and money you can invest in maintenance.

 

Here are key features to look for:

• Solar Reflectance Index (SRI): Higher values reflect more sunlight, keeping the surface cooler.

• Thermal Expansion Rates: Materials that expand too much may develop cracks or buckling.

• UV Protection: Look for coatings that include additives to block harmful rays.

• Certified Materials: Use surfaces that meet standards set by ASTM or the ASBA.

​

Materials with heat-resistant properties may cost more upfront but tend to last longer and require fewer repairs.

What Maintenance Practices Help Protect Court Surfaces in the Summer?

Even durable surfaces need the right care during extreme heat. Regular maintenance extends the life of the surface and keeps it safe for users.

 

Best practices include:

• Inspect Courts Often: Check for cracks, bubbling, or fading, especially after hot days.

• Avoid Midday Repairs: Early morning or late afternoon is the best time to apply coatings or do repairs.

• Cool the Surface: A light mist can lower the temperature before games or events.

• Use Shade: Shade structures or nearby trees can protect the court from peak sun exposure.

​

What New Materials Are Designed to Withstand Heat?

Recent innovations in court materials are helping facilities handle heat better than ever:

• Infrared Reflective Coatings: These help keep surfaces cooler by reflecting more heat away.

• Ventilated Shock Pads: Used beneath modular courts, they allow air circulation and reduce surface stress.

• Smart Sensors: Newer court systems can include temperature sensors that alert staff when heat levels rise.

​

Conclusion

Summer heat offers a clear test for court surface durability. The choices made during planning—materials, coatings, construction methods—can determine whether a surface holds up or breaks down.

​

Long-lasting courts don’t happen by accident. They result from smart design, high-quality materials, and consistent maintenance.
