Paints and varnishes – Undercoats for paints
Description
Specifies requirements for two grades of undercoat for use under air-drying paints. The undercoat is also used for application over primed steel and wood, on sealed and primed masonry, hardboard, compressed fibre-board and similar materials used in the construction and furnishing of buildings.
Grade 1 undercoat is a high hiding power undercoat that will allow a reduction in the number of coats in the paint system necessary to obtain complete obliteration of the substrate.
Grade 2 undercoat (utility grade) is a low hiding power undercoat.
