Why Pour On Gravel Binder
Simply pour on and stabilise.
StoneSet developed Pour On Gravel Binder in 2010 to meet demand for a more affordable, accessible alternative to full resin bound paving. Designed for DIY users, homeowners, and landscapers; Pour On provides the stability of a resin-bound surface while maintaining the natural look and permeability of loose gravel without specialist installation or higher material costs.
Pour On uses advanced single-part (1K) polyurethane resin technology that is ready to use straight from the pail. No mixing is required. The resin is moisture-curing, reacting with air humidity to form a stable, permeable matrix that binds stones in place while preserving the aggregate’s natural appearance. Once cured, the surface is safe to walk on for kids and pets.
We supply two resin types to suit your project:
Clear (aliphatic) UV-stable resin – Fully UV-resistant and remains transparent long-term. Recommended for all outdoor projects, especially when using light-coloured or decorative aggregates, where maintaining the stone’s natural colour is essential.
Amber (aromatic) non-UV-stable resin – Yellows or darkens under sunlight exposure. Works acceptably with dark aggregates (brown, black, deep greys), but may noticeably change the colour of lighter stones.
Compared to water-based alternatives, polyurethane systems consistently outperform in strength, durability and long-term performance. Polyurethane binders offer superior:
- Flexibility
- Adhesion
- Resistance to weathering, UV, chemicals and wear
- Ability to absorb movement without cracking
Water-based binders such as Pour On Gravel Binder Light are often cheaper or easier to clean up, but they generally cure weaker and deteriorate faster especially under moisture, UV exposure, or freeze-thaw cycles. For Australian conditions, StoneSet’s polyurethane formulation remains the industry benchmark for stabilising and protecting decorative gravel surfaces.
