Lime - Putty & Hydraulic

Fat Lime Putty - Ty-Mawr

This lime is produced by slaking fresh British Quicklime in an excess of water. It is also known as non-hydraulic lime because it requires exposure to air in order to carbonate and does not set under water. This lime is regarded as the most appropriate lime for old buildings where maximum permeability and flexibility is required.

This is a dry powder lime produced from limestone containing clay and other impurities which enable it to set without exposure to air; it is therefore used for providing a faster initial set in more extreme conditions including under water.

The Castle Cement product is a white French lime so can be used in situations where a bright white lime mortar is required.
