Ty-Mawr Limewash

Pass+
Limewash- mineral paint from lime putty

'Limewash has been used for thousands of years as a decorative and protective finish for internal and external wall applications. It has gained popularity again because it is 'technically' correct for use on old buildings (i.e. it allows moisture to evaporate) which helps to protect the building fabric and maintain a healthy environment. It is also 'kinder' to the environment than modern alternatives.

Limewash is made from slaked quicklime and water. It sets through a natural process known as carbonation i.e. it absorbs carbon dioxide given off during burning gradually returning to its original form (CaCO3), it then naturally weathers and degrades, returning to the ground, hence creating a cycle - the Lime Cycle
