The organic materials that constitute fabric supports deteriorate to a greater or lesser extent over time, losing their characteristics of elasticity and having a negative impact on the upper preparation and paint layers, causing losses in adhesion and flaking. Furthermore, inadequate conservation conditions and frequent interventions in the past, such as excessive cleaning and repainting, contribute to the deterioration of this type of artwork. The processes of restoring canvas paintings are carried out using different procedures and methodologies depending on the construction technique, the characteristics of the artwork and its state of conservation. The process of determining the intervention method begins with a preliminary study of the work followed by the application of scientific research techniques such as X-ray and analytical stratigraphy studies when deemed necessary. Graphic and photographic documentation of the initial state and different phases of the restoration process are essential to the project.
