How to Choose the Right EPDM Granules for Your Project?
Choosing the wrong EPDM granules can lead to fading colors, poor elasticity, or even safety issues in playgrounds and tracks.
To choose the right EPDM granules, match the granule size, binder ratio, and thickness to your project’s function—whether for kindergartens, public parks, or athletic tracks.
When it comes to outdoor flooring, every detail matters. I’ve worked with clients across Australia, Spain, and Canada who needed EPDM surfaces for everything from preschool playgrounds to national park trails. Let’s walk through how to choose the right EPDM granules for your project—and avoid costly mistakes.
What Granule Size Should You Use—1–3mm or 2–4mm?
Use 1–3mm EPDM granules for smoother finishes and fine detailing; go with 2–4mm for better texture and slip resistance in high-impact or outdoor spaces.
Granule Size | Best For | Surface Feel | Durability | Application Examples |
---|---|---|---|---|
1–3mm | Logos, indoor play, visual design | Smooth & refined | Medium | Kindergartens, detailed logos |
2–4mm | High-traffic outdoor zones | Textured & grippy | High | Parks, sports tracks, public walkways |

How Does PU Binder Ratio (Glue Content) Affect Performance?
A 22% PU binder ratio provides a good balance of elasticity and durability for most outdoor applications like playgrounds and tracks.
PU Binder Ratio | Elasticity | Durability | Recommended For |
---|---|---|---|
18%–20% | High | Low | Temporary events |
22% (Standard) | Balanced | High | Playgrounds, parks |
25%+ | Low | Very High | Heavy-use areas |
What Thickness Is Recommended for Safety Zones?
We recommend a poured-in-place EPDM surface thickness of 10–15mm for playgrounds and other safety zones.
Thickness | Cushioning | Use Case |
---|---|---|
8–10mm | Light | Walkways |
10–12mm | Medium | Schools, parks |
13–15mm | High | Playgrounds, tracks |

Which EPDM Material Should You Use for Different Applications?
For kindergartens, use soft, UV-stable granules with bright colors; for parks, choose thicker, textured granules; for tracks, prioritize elasticity and grip.
Application | Recommended Granule Size | Color Choice | Extra Notes |
---|---|---|---|
Kindergarten | 1–3mm | Bright colors | Safety & visuals |
Public Parks | 2–4mm | Natural tones | UV-resistant |
Running Tracks | 2–4mm | Any | High elasticity |
