Problem Solver - Lime Plaster
Other Problems
Lime plaster is type of plaster composed of sand, water, and lime, usually non-hydraulic hydrated lime (also known as slaked lime, high calcium lime or air lime) Non-hydraulic lime plaster can also be made to set faster by adding small quantities of gypsum plaster.
Preparation
Dry brush the surface down using a stiff bristle brush to remove any loose materials
If any mould or mildew is apparent, treat with a suitable fungicidal solution, rinse again with clean water and allow to dry.
Depending on surface substrate check condition and carry out any remedial works required to make sound
Topcoat
Once the surface is clean and all loose material has been removed, paint with a limewash if that is the finish required.
Or apply an appropriate breathable topcoat and allow to dry, followed by a 2nd coat to finish.
