Comparing Suitable Kits and Binders for Asphalt Overlays

Choosing the right system is crucial for a long-lasting resin bound gravel surface over asphalt. Factors such as drainage, resin type, UV resistance, and the appearance of aggregates should influence your decision.

If you are looking for a complete, user-friendly solution designed specifically for UK outdoor spaces, the “Flowstone” – Complete Permeable Floor Kit with Pebbles and Resin is an excellent choice. This kit includes everything required for a permeable surface that allows water drainage, helping to prevent puddles and waterlogging on driveways and patios. It also offers detailed resin guidance to ensure long-lasting colour when using white or coloured stones.

For those seeking more flexibility with decorative finishes, “Trasparente” – Epoxy Binder for Coloured Pebbles and Grits is a transparent, UV-stable system engineered for coloured aggregates and warm or dark stones. Its crystal-clear finish, low viscosity, and non-toxic certification after curing make it ideal for both professional and DIY installations requiring vibrant, permeable outdoor floors.

If you plan to create elegant designs with white stones, the best solution is the “Polirock” – Polyurethane Binder for White Stones, 2kg Two-Component Kit. This specialised polyurethane binder offers excellent weather and UV resistance, ensuring the surface remains clear and resistant to yellowing—crucial for maintaining the look of white or natural aggregates over asphalt bases.

Advantages of Overlaying Resin Bound Systems on Asphalt

Applying resin bound gravel over existing asphalt is not only possible—it is also highly beneficial. Asphalt provides a stable, solid sub-base that, when properly cleaned and prepared, allows resin bound surfaces to bond strongly, forming a robust, crack-resistant finish suitable for driveways and walkways. Permeable systems like Flowstone can transform your space by delivering rapid drainage, reducing puddling and supporting sustainable urban drainage standards.

The use of high-performance binders such as Trasparente epoxy binder ensures that decorative coloured pebbles remain vibrant and securely fixed, even in high-traffic areas exposed to fluctuating weather. For designs where clarity and UV-resistance are paramount—particularly with white stones—Polirock polyurethane binder prevents yellowing and maintains an attractive anti-slip surface.

Preparation and Application: Best Practices

Before installing any resin bound system over asphalt, it is essential to ensure the existing tarmac is in sound condition, free of major cracks or oil contamination. Cleaning the surface thoroughly and repairing any damage will promote better adhesion and extend the lifespan of the overlay.

Once prepared, application is straightforward—especially with comprehensive kits like Flowstone that supply all necessary materials and clear step-by-step instructions for DIY and professional users. Both Trasparente and Polirock binders are designed to mix thoroughly with clean, dry aggregates before trowelling onto the prepared asphalt, ensuring even resin distribution and optimal mechanical strength.

After curing, your resin bound surface will not only protect the underlying asphalt but also significantly improve the overall appearance and safety of your outdoor areas.
