Polyurethane Binder FAQs
A PU binder (polyurethane binder) is a specialised adhesive used to bond rubber granules together in surfacing applications such as playgrounds, sports courts, and recreational flooring. It creates a strong yet flexible surface layer that can withstand high use and varying weather conditions.
There are two main types:
- Aromatic binders – Economical and suitable for most base layers or areas not exposed to direct UV light.
- Aliphatic binders – UV-stable and non-yellowing, making them ideal for top layers where colour retention and aesthetics matter.
Aloro’s PU binders are designed for optimal performance with our full range of rubber surfacing granules, including:
The mix ratio depends on the specific application and whether the binder is being used for a base layer or top layer. It’s essential to follow the technical data sheet provided with your binder, or contact our technical team for guidance on correct ratios.
Polyurethane binders are sensitive to temperature and moisture.
- Curing is faster in warm, humid conditions
- Curing is slower in cooler, drier weather
- Installation should be avoided during rain or just before rainfall
