Biodeterioration in building façades represents an important economic loss related to maintaining a functional protective coating system. Research papers with long-time studies on paint performance exposed field conditions are scarce. Fungi, cyanobacteria, and algae frequently present biofilms formed outdoor locations. Among these, defacement caused by fungi is known for the broad damage spectr...

This paper presents a survey of significant developments in research on the leaching of oil paint films by organic solvents, from the first systematic investigations carried out in the 1950s to more recent “clinical” studies involving the sampling and analysis of paintings during treatment. Key studies are discussed in the context of an improved knowledge of oil paint chemistry that has develop...
