OBSERVATIONS: |
Tradesmen familiar with the use of lime, and with experience of its successful
use should be employed. Non-hydraulic lime mortars do not perform as modern
cementitious materials. Non-hydraulic lime putty sets by the reaction
with atmospheric carbon dioxide in the presence of moisture. This 'carbonation'
is a slow process and control of the drying and curing process by 'tending'
and protecting is crucial to success and long term performance. See RJ2.03 - "Use of Bedding + Pointing Mortars" information sheet . See Tan.02 - Tempering of lime putty mortars and plasters. |
