Specialist traditional lime putty repointing - Oxfordshire (Fully certified).

Lime putty was used historically to make mortar but to make the best mortars it has to be well matured. The reason for this is that the maturing process reduces the grain size of the slaked quicklime which means the mortar becomes more weather resistant and more resilient to the outside environment.

Before: Buckland cottage.



After: a coarse grain lime mortar with the addition of fine washed sand.

Lime putty (commonly referred to as non-hydraulic lime or fat lime) is a product used exclusively on older properties. It's origin can  be traced back as far as Roman and Egyptian times.

Putty should preferably be used when temperatures are 10 degrees or above.

When you know the right tools, procedures and mortars there's no telling what can be achieved.

Please see the photos below for examples of what this looks like when mixed with a good sand.

The best putty to use is one which has been matured for years.

When to use putty:

  • Non-hydraulic lime is compatible with weak and weathered stone
  • If your building is old and is prone to movement because it sits on insubstantial foundations then lime putty is ideal because it is argued to be the most flexible mortar and many believe it copes better with settlement
  • When it is important that mortar and not the stonework becomes the sacrificial element in the building.

When not to use lime putty: 

When the building is very damp. Putty requires a dry environment to cure. Damp buildings prevent this therefore NHL or quicklime with pozzolan should be used as this will set in the presence of moisture. This will enable it to cope with:

Very exposed areas and chimneys.

The winter months.

When curing times are a priority.

Before: earth-lime built barn in Hampton Poyle.

During: rake out and new mortar application.

After final brushing. Now carbonation starts.
