Varnishes are applied over dry paint films to protect the painting surface from the environment and protect the pigments from ultraviolet light. Varnishes are also used to change or unify a painting’s surface sheen. Liquitex varnishes come in several different sheens, which can all be intermixed for a customised sheen. Liquitex varnishes are either permanent or removable and can be applied to both flexible and rigid supports.
