The quality of the preparation determines to a large degree the eventual durability of the work.
Paper, cardboard, wood, cotton and linen, for example, can serve as grounds for oil colour, but not without first being treated. An untreated or insufficiently prepared ground would absorb the oil from the paint and would eventually be damaged by the oil. A layer of paint must have enough oil to surround the pigments and to form a good film. Only then are the pigments sufficiently bonded and early cracks avoided. Talens Gesso Primer has all the necessary properties for a durable result.
