Key Features

  • Blue Circle Hydralime is a hydrated lime used for increased plasticity & cohesiveness in cement, mortars & renders
  • Fine, white, dry powder which lightens and brightens mortars
  • A high calcium, non hydraulic, hydrated lime
  • Makes floating renders and pointing mortars easier
  • Hydralime can be used for traditional nominal mixes for mortars and renders in conjunction with standard Portland based cements or in lime-washes without cement

Technical Information

  • Hydralime may not be used for general concreting, screeds or grout.
  • For mortars and renders Hydralime should always be mixed with cement and sand components.
  • The final finish quality of this material will depend on the operative having the required skills and a familiarity with the material and its application methods.
  • Normal site practice to the relevant British and European Standards should always apply. Tarmac Cement UK cannot be held responsible where workmanship has not been carried out in accordance with good practice.

The maximum benefit of Hydralime can be obtained by its use in a lime putty. This is produced by adding an excess of Hydralime to water in a clean container with constant stirring to form a paste, which is allowed to condition by standing for 24 hours before use. Do not allow to dry out during this time.

* Note that as Hydralime is non-hydraulic, it is not suitable for use in mortars and renders without a Portland cement.
