    Abstract

    The paper deals with the durability of experimental emulsion-based systems on wood exposed to weathering for a period of 3 years.

    A number of oleo-resinous and emulsion-based primers were applied to two different types of timber and overcoated with both conventional oleo-resinous and emulsion-based topcoats.

    Four different exposure sites representing four different climatic regions were chosen to allow a study of the influence of the following on the durability of the coating systems: the composition of the paint system, the primer formulation, the topcoat formulation, and the climatic conditions.

    It was found that emulsion-based systems could be more durable than the more conventional systems.
