• Cost-effective renewal: “Flowstone” provides a simple way to refresh worn-out surfaces, protecting them for years to come with ready-included materials.
• Customisable finish: Both systems are compatible with various aggregate sizes and shades, allowing you to create bespoke patterns or subtle, elegant settings.
• Simple application: All skill levels are catered for, with stepwise instructions and no specialist training required.
• No Yellowing: “Polirock” retains clarity on white pebbles, ensuring a fresh look whatever the weather.
• Weather-Resistant: Both kits resist the effects of UV rays, rain, and thermal shock.
• Anti-Slip Finish: Especially important on terrace steps and shared spaces, minimising the risk of slips year-round.
• Customisable: “Polirock” works with a wide range of natural aggregates, opening up even more design options for your terrace.

The “Flowstone” – Complete Permeable Floor Kit with Pebbles and Resin is recommended for most terraces, thanks to its all-in-one approach and precise guidance on resin binder selection for specific stones (for example, use a non-yellowing polyurethane binder if you’re using white aggregates). It’s important to avoid applying epoxy binders to white Carrara gravel, as described in its usage guidelines.

For those aiming for a flawless white or light finish, “Polirock” – Polyurethane Binder for White Stones, 2kg Two-Component Kit delivers, maintaining bright tones and resisting the yellowing commonly seen with other binders.

How to choose the best resin bound gravel kit for your terrace?

Your selection should consider substrate preparation, drainage requirements, and desired finish. “Flowstone” is great for a wide array of environments, especially where puddling and water run-off pose concerns. Thanks to its permeable nature, water disperses straight through to the subsoil, helping keep your terrace safe and dry even after heavy rainfall.

If you live in an area with prolonged sun exposure or have a strong preference for white stone elegance, opt for “Polirock”. Its unique two-part polyurethane chemistry offers lasting weather resistance and will not yellow, making it the clear choice when colour preservation is essential.

Both options work on cementitious and existing firm substrates, though it’s important to make sure surfaces are dry and ready for resin application. For ambitious projects or large terraces, consider using a cement mixer with either solution to make the mixing process smoother.

Installation tips and maintenance

Both “Flowstone” and “Polirock” are engineered for straightforward application by DIY enthusiasts and professionals alike. Always follow the included instructions to achieve the best results. Clear surfaces of dust, oils or standing water before installation. Once cured, these surfaces are known for their longevity and ease of upkeep — just sweep regularly and rinse as needed. With such durable solutions, your terrace will remain beautiful and functional for years to come.
