RJ1.07 WELSH WHITE LIME PUTTY |
PRODUCT DATA SHEET |
DESCRIPTION: |
Traditional lime putty slaked from Carboniferous limestone burnt in a
coal fired kiln. The burnt clays, coal ash, and un-burnt limestone impurities
present have a beneficial effect, and this putty may have weak hydraulic
properties. |

USES: |
To be mixed with sands, stone-dusts and aggregates normally at 1:2½
to produce lime putty bedding and pointing mortars and internal haired
basecoat plasters. |
AVAILABILITY: |
30 day + 100 day Mature. Ex Stock. |
SHELF LIFE: |
Matures and improves with age when kept in sealed containers. Protect from frost and heat. These traditional putties will stiffen during storage, but can be plasticised without the addition of water by thorough mixing. |

HEALTH & SAFETY |
Alkali pH 12.5. Eyes, open sores and cuts, and skin must be protected.
|
OBSERVATIONS: |
Tradesmen familiar with the use of lime, and with experience of successful
use should be employed. Accurate site mixing is essential. Traditional
limes do not perform as gypsum plaster and modern cementitious materials.
Lime 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 setting process by tending and protecting is crucial to success and
long term performance. Do not use in temperatures of 5ºC or less, and protect from frost.. |
