Resin binders are the crucial adhesive in permeable flooring kits, securing decorative aggregates into a durable, weather-resistant surface that allows effective drainage. Knowing your options and how to select the right binder ensures both lasting strength and a high-quality finish.
What is a Resin Binder?
A resin binder is a specialist adhesive mixed with natural aggregates, such as pebbles, to form resin-bound permeable floors. It not only holds the stone together firmly but also creates tiny gaps for water to pass through, preventing puddling and slip hazards. The result is a robust outdoor surface suitable for patios, driveways, and public spaces.
Types of Resins: Choosing the Right Binder
Most resin flooring kits include guidance for the suitable binder to match your chosen aggregate. Typically, polyurethane resin is ideal for white stones, as it’s less likely to yellow over time. For coloured or darker granules, a low-yellowing epoxy binder is preferred to maintain their vibrancy. Always refer to kit instructions for precise selection and follow recommended ratios for effective results.
To explore a complete solution, take a look at the Flowstone Complete Permeable Floor Kit which includes tailored resin and aggregates with step-by-step instructions.
When Resin Binder Selection Matters
- If the resin colour or clarity is crucial to your project’s look.
- In areas exposed to sunlight – choosing non-yellowing options helps preserve finishes.
- When matching binder to aggregate to ensure optimal bonding and drainage.
