Lime Washing at Mill Hill
Back in 2019, Heritage Lincolnshire staff and a team of fabulous volunteers lime washed the whole exterior of Mill Hill Cottage, they also limewashed areas within the property.
When using lime it is important to carry out safety measures the whole group wore coveralls, goggles and gloves to protect themselves, as limewash is caustic.
In preparation vegetation, algae and cobwebs were removed before the lime wash was applied. This was done to ensure that wash took properly and did not come away from the building.
The group then moved on to mixing the lime wash where equal amounts of lime putty were mixed, we then added until we reached the desired consistency. Pigment and water were then mixed separately, creating a paste which was then added to the lime wash mixture. The colour of the mixture was a bright orange colour but after a couple of months its appearance was more of a buttery yellow.
Before applying the limewash water was sprayed onto the wall to create a little dampness on the wall before painting. For limewash to stick, it depends on suction between itself and the surface of the wall. Limewash is perfect for natural materials such as lime renders/plasters, brick, and stone however be wary as it will not work so well with modern materials/finishes.
When applying the limewash we used well-made paintbrushes instead of using a paint roller as it can create an uneven and rough surface. To ensure a perfect consistency continually stir the limewash during application as lime particles quickly settle to the bottom of the container.
The Group later moved on to limewashing inside of the cottage, water was further added to the mixture as it had been stored overnight.
Extra care had to be taken to ensure that the limewash was not splattered onto the furniture and flooring.
