How to install safety playground field surfaces? EPDM TPV rubber granules for safety flooring.

How to install safety playground field surfaces? Installing PIP (Pour-in-Place) jiadong EPDM TPV granules is a fairly precise process—done right, it gives you a seamless, durable rubber surface (common for playgrounds, tracks, and courts). www.safetytrackfield.com 1. Prepare the Base (Most Critical Step)
A stable base prevents cracking and delamination.
Common base options:
Concrete (best for longevity)
Asphalt (must be well-cured, at least 28 days)
Compacted aggregate (only for non-critical areas)
Requirements:
Clean (no dust, oil, debris)
Dry (moisture causes bonding failure)
Smooth and level
Proper slope (≈1–2%) for drainage
Prime the surface with PU primer to improve adhesion.
2. Install the Base Layer (SBR Rubber or ETPU granules)
This is the shock-absorbing layer under EPDM or TPV.
Material:
Recycled SBR granules or ETPU foam granules
Aromatic PU binder
Steps:
Mix thoroughly in a forced mixer
Spread evenly (usually 10–50 mm thick depending on use)
Trowel and compact
Let cure (8–24 hours depending on weather)
3. Install the EPDM or TPV granules Top Layer
This is the visible, UV-resistant layer.
Material:
EPDM granules or ETPU granules (colored)
Aliphatic PU binder (important for UV stability)
Steps:
Mix until all granules are evenly coated
Pour onto the cured SBR or ETPU base
Spread to ~10–15 mm thickness
Trowel smooth (use release agent to prevent sticking)
🧪 4. Curing
Initial set: 12–24 hours
Full cure: 48–72 hours
