Lime Green Prompt Mortar
A specialist mortar which combines the benefits of lime with the rapid set of Roman Cement. Suitable for building and pointing stone and brick in demanding situations.
Lime Green Prompt mortar is one of our ‘conservation mortars' used in the repair of historic buildings. As its name suggests, Prompt mortar sets rapidly, which makes it the perfect solution for those situations and climatic conditions where normal hydraulic lime mortar would take too long to go off. This, combined with its low strength, ease of use and long-life performance makes it a first choice for conservation work and restoration projects. It can also be used for repair of early proto-cements.
This fast set prompt mortar is available in a range of colours and can be supplied in 25kg sacks for ease of handling.
