Ultra Series Stabilised Mortar is highly popular as it is ready mixed at our plants and delivered to sites before the shift starts. Unlike traditional mortar, Ultra Series Stabilised Mortar can remain wet inside the tubs it is delivered in for up to 36 hours before it begins to set. However it will begin setting when it is applied by the mason. This provides significant savings to project managers in wastage, time and materials while ensuring unrivalled consistency and quality of finish.
