Parge coat
The term ‘parge coat’ refers to the application of a thin coat of a cementitious or polymeric mortar to concrete or masonry walls.
Parging (or sometimes 'pargeting') is commonly used as a method for improving the thermal and acoustic performance of walls before before finishing them with a final surface such as drylining.
A parge coat can reduce air leakage through cracks, joints and porous wall constructions and so reduce energy consumption and improve comfort and acoustic performance. It can also be used to prepare a surface for a topcoat.
The parge coat is typically applied by hand, or by spraying, in a continuous coating with a minimum thickness of 6mm. As the walls are then finished with a subsequent top layer, it is not necessary to smooth the parge coat to a perfectly flat surface.
