UltraScape Pro-Prime Slurry Primer creates a powerful bond between paving elements and UltraScape bedding mortar, ensuring long‑lasting stability and reducing the risk of costly installation failures. It can also be applied between the roadbase and bedding mortar layer to further enhance overall system strength. Traditional methods of laying paving directly onto bedding mortar can lead to movement and failure over time—Pro‑Prime eliminates this risk with a reliable, BS 7533‑compliant solution.
