Mature Lime Putty

Roundtower Lime Putty is a premium, high-purity binder made from high-calcium quicklime sourced from Buxton, Derbyshire, and slaked in the traditional way—stored in pits and matured for a minimum of four months. This careful process ensures complete hydration and results in a fat, highly workable putty with a bulk density of approximately 1350 kg/m³.

Understanding lime putty density is essential: lower-density putties have higher water content and reduced available lime, which may require adjustments when used in mortars or plasters.

✔️ Available Sizes: 25kg tubs, and bulk bags
✔️ Bulk Density (RBD): ~1350 kg/m³
✔️ Guaranteed Maturation: Minimum of 4 months
✔️ Binder Type: Pure non-hydraulic lime (calcium hydroxide)
