How to Maintain Wet Pour Rubber Surfacing for Playgrounds and Parks
Wet pour rubber surfacing is a popular choice for playgrounds, schools, and parks due to its safety, durability, and colorful design options. But like all outdoor materials, it still requires proper maintenance to stay in top condition.
With regular cleaning, routine inspection, and timely repairs, wet pour rubber can stay safe, attractive, and functional for many years.
Here’s a complete guide on how to maintain wet pour rubber surfaces.
What Is Wet Pour Rubber?
Wet pour rubber is a seamless surface made by mixing EPDM granules with a PU (polyurethane) binder, installed on-site over a base layer like concrete or asphalt. It is widely used in:
- School and public playgrounds
- Outdoor fitness areas
- Jogging tracks
- Accessible pathways and parks
Its advantages include impact absorption, non-slip texture, and the ability to design custom graphics and patterns.

Daily and Weekly Maintenance Tasks
Simple routines can help prevent long-term damage:
| Task | Frequency | Tools Needed | Purpose |
|---|---|---|---|
| Sweeping leaves | Daily | Broom or leaf blower | Prevent staining or moss |
| Rinsing surface | Weekly | Low-pressure hose | Remove dirt and dust |
| Spot-clean spills | As needed | Mild pH-neutral cleaner | Avoid permanent discoloration |
Avoid using harsh chemicals or high-pressure washers, which can damage the binder or loosen granules.

Seasonal and Long-Term Care
Each season brings different environmental stress:
- Spring/Fall: Inspect for edge separation, bulges, or loss of granules
- Summer: Don’t leave heavy equipment or metal objects on the surface for long
- Winter: Avoid shoveling snow with metal tools, which can cut or peel the surface
- Annual: Consider applying a UV-protective coating to preserve colors longer
Professional inspections once a year can detect early damage and save repair costs.
When Should You Repair Wet Pour Rubber?
Look for:
- Cracks deeper than 3mm
- Color fading or delamination
- EPDM granules detaching in 20×20 cm or larger areas
Repairs should use matching granules from the same color batch when possible. For safety-critical areas like under swings or slides, repairs should be done immediately.
Tip: DIY repair kits exist, but professional repair ensures better bonding and long-term performance.
Tools and Cleaning Products to Avoid
Avoid the following tools and cleaners:
- Steel wire brushes
- Bleach or acid-based chemicals
- Gasoline or solvent cleaners
- High-heat pressure washers
These may damage the polyurethane binder or degrade the EPDM color and elasticity.
Common Questions About Wet Pour Maintenance
How long does it last?
A properly maintained surface can last 8–15 years, depending on UV exposure and usage.
Can I pressure wash it?
Use only low-pressure water. High PSI may damage the surface.
Does it grow mold?
Rarely—but in shaded, wet areas, moss or algae can form. Use a diluted eco-friendly anti-moss cleaner.
How to remove paint or graffiti?
Use mild graffiti remover or consult a specialist. Test a small area first.
