The quality of the primer determines to a high degree the longevity of a workpiece. Paper, cardboard, wood, cotton and linen can serve as a base for oil paint, but all substrates must first be pretreated. An untreated or incompletely prepared substrate absorbs the oil from the paint and is permanently touched by the oil. A coat of paint must contain a sufficient amount of oil to surround the pigments and form a good film. Only then will the pigments be sufficiently bound and early cracking will be prevented. Even a too closed ground offers all the conditions for a long-lasting result. Talens Gesso Primer offers all the prerequisites for a long-lasting result.
