25Kg Hydrated Lime


Please Call Us

Castle Hydrated Lime is produced to comply with the requirements of BS EN 459-1:2001 Building lime type CL 90(S).

It is recommended for use in cement: lime: sand mortars for brick and block laying, external rendering and for internal plastering.



Castle Hydrated Lime as a constituent of cement: lime: sand mortars can be used for a wide range of applications for jointing mortars, renders and plasters. Together with Castle Ordinary Portland Cement and a suitable sand the mortar will have excellent workability and good water retention when applied to most bricks, blocks and surfaces to be rendered or plastered.


Quality: Castle Hydrated Lime is produced by precisely controlled hydration methods from selected quicklime resulting in a product of high purity.



  • Very high strength is not normally required of building mortars. An unne­ces­sarily strong mortar will concentrate the effects of any differential movement between the mortar and the brickwork and cracks may appear which could reduce the durability and increase the risk of penetration by rain.
  • A weaker mortar will accommodate some differential movement between the mortar and the brickwork and if cracking does appear it will generally be distributed as hairline cracks in joints, thus preserving the integrity of the bricks or blocks themselves. Subsequent movement of moisture through the mortar will act with the lime to produce autogenous healing of the hairline cracks formed.
  • In general the mortar should be weaker than the bricks or blocks and this is particularly important with concrete blocks which may have a high drying shrinkage.
