Marshalls Instarmac Pro-Prime Slurry
Slurry Primer
Marshalls UltraScape Pro-Prime slurry primer comes in a 20kg paper bag and is used to provide an exceptionally strong bond between paving and bedding mortar. It is easy to use as only requires the addition of water. Traditionally paving elements would be laid directly onto the bedding mortar, which with general wear and tear and increasing traffic load bearing, could result in costly and high profile failures. Pro-Prime helps to eliminate this.
