LIME PLASTER

The use of lime for plastering, both internally and externally, has been practiced around the world for millennia. Lime plasters are ‘kinder’ to the fabric of older buildings and can help reduce or eliminate some of the problems associated with using cement based plasters.

Some of the advantages of using lime plasters include

  • The porous nature of lime plasters allows water vapour to escape which can help reduce damp problems.

  • Lime plaster is more flexible than cement based plaster which allows it handle building movement more effectively with less chance of cracking

  • If lime plaster does crack the presence of ‘free lime’ gives it the ability to self-repair.

  • Lime plaster can help reduce condensation problems in the building.

 

Buildings built Pre-1919 were mostly constructed using solid walls. This means they did not have a cavity to stop the ingress of water from the outside to inside of the building. The use of lime provided a solution to the ingress of water by allowing the building to ‘Breathe’.

 

The porous nature of lime plasters and renders allows moisture to be absorbed (breathe in) into wall but it also allows moisture to evaporate back out (breathe out). The use of non-porous materials in the building (paint, cement etc.) can cause this moisture to become trapped which can lead to penetrating damp and/or failure of the plaster.

 

Lime plaster can not only help prevent problems associated with damp but it also has a very aesthetic warm, natural feel that can add to the beauty of your home. Lime plasters can be finished in a wide range of colours using lime wash or clay paints. If painting is not your thing lime plaster can also be dyed in a range of natural colours, keeping maintenance to a minimum.
