High calcium, fat lime putty (class A) is soft, breathable and extremely flexible, it is matured for at least 120 days. This material is used to make non-hydraulic lime mortar, plaster and render for building conservation projects.
Lime putty is manufactured by slaking quicklime in clean water then leaving it to mature. It sets by carbonation; the carbon in the atmosphere causes it to set.
The material is packaged in a tough, reusable plastic bucket (recyclable) which will prevent it setting. It can be stored indefinitely if it is kept sealed, airtight inside the bucket.
