Lafarge Hydrated Lime, 25Kg Bag 

This high calcium, bagged hydrated lime is typically used to improve the flexibility, cohesiveness and water retention of Portland cement mortars and renders, and for lime-washes without cement.

Perfect for both lightening and brightening mortars, this fine, dry white powder is the purest grade of hydrated lime for building, conforming to BS EN 459-1 CL 90-S.

Our hydrated lime has no use by date when stored correctly, and is available in 25kg bags for ease of use.

Mixing Guidance

Lafarge hydrated lime is created by calcining limestone or chalk in a high-temperature kiln to produce quicklime, which is then hydrated under carefully controlled conditions to produce a fine, white calcium hydroxide powder.

For a general mix for mortars and renders, one part hydrated lime should be combined with one part cement and five parts soft building sand. Our hydrated lime should not be used for general concreting, screeds or grout.
