Putty (finishing plaster) is applied on the wall surface in an interior space to smoothen it prior to application of paint. This is done for all wall surfaces, i.e.., brick-sand-cement or plaster boards.
Traditional putty cannot remove undulations in the surface in excess of 1 mm, which becomes a product limitation. In addition, inappropriate mixing of enamel-water in plasters can result in flaking of the painted surface.
Gyproc Champion Putty is made from high purity gypsum and provides protective base for expensive paints. Its superior water-resistance prevents paint from flaking even if the walls are damp. Special additives also offer anti-algal and anti-fungal protection.
