Seal and Protect as Required: Safeguarding Your Permeable Paving

Properly sealing and protecting your permeable paving not only maintains its functionality but also extends its lifespan. This guide will help you select the most suitable sealants and binders to ensure your resin-bound surfaces stay resilient in changing UK weather.

Choosing the Right Binder and Sealant

Selecting the correct binder is essential for both durability and appearance. For white or light-coloured stones, a non-yellowing polyurethane binder such as Polirock helps prevent discolouration over time. For coloured aggregates, a transparent epoxy resin with UV resistance – like “Trasparente” – is ideal to ensure clarity and avoid yellowing. Always match your binder to your chosen aggregate for best results.

Application and Protection Tips

Thoroughly mix your aggregate and binder to coat each stone before installation; avoid pouring resin straight over loose stones as this prevents proper encapsulation. It’s also vital to apply sealants during suitable weather conditions, steering clear of extremes in temperature or humidity to guarantee proper curing. Following step-by-step product instructions ensures even application and a fully bonded surface layer.

When This Matters Most

Areas with heavy foot or vehicle traffic benefit from the added strength and longevity of a well-sealed surface.
Spaces exposed to regular sunlight or moisture require UV-stable, weather-resistant sealants to avoid rapid wear or colour changes.
