Historic Facade refurb 2013

This project involves the refurbishment of an Historic facade as part of an overall refurbishment of this building. In this process the existing paint finishes were removed and repairs undertaken to the plaster before coating works were undertaken. With Historic facade works it is vitally important to understand the nature of the surfaces being treated. Older buildings need to breathe to release moisture inherent in any of these structures. The ability to "breathe" allows for an equilibrium to exist, and this is important with faacdes made with tradition permeable lime based plasters.  Treatment can sometimes involve removing defective weak plaster layers and replacing with new plaster and this is required for a variety of reasons. However we do not advocate the use of modern plasters in Historic repairs. These are often filled with modern resins and binders not suitable to old plasters which were often hand manufactured on site using traditional methods. These traditional plasters were often lime rich mortar which in comparison to todays mixes are softer and "breathable". When you apply a modern "rigid" repair plaster to a Historic plaster substrate you run a risk of the repair failing due to the uneven forces between the two materials competing against each other. Secondly it is important to choose the correct Historic facade coating system so that the coating system is in tune with the plaster and will allow the building to "breathe". In this case we elected to use Keim Paints as they are considered to be the best Historic facade coating manufacturer in the world today.
