Exterior wooden applications often require a protective coating to ensure the functionality of the building or for decorative purpose.It is well known that fungi will grow on the coating surface or even in the wood(know as blue stain).Therefore usually a biocide protection is absolute essential preventing this circumstances.Aureobasidium pullulans has been the most frequently isolated fungus causing blue stain in service and has been shown to be one of the major colonisers of wood and wood coatings(Ross et al 1968,Savory 1973,Winters et al 1978,winters and Guidetti 1978,Jakubowski et al 1983,O'Neill 1986).It could be shown that the coating influences the fungi growth but also the penetration nutrients migrating from the wood to the surface of the paint film.The opinion concerning how penetration occurs is divided.Mendes(1982)observered penetration of Aureobasidium pullulans through the varnish when the coated block was placed over malt extract aaar.Several authors suaaested A.
