This white universal primer providing good coverage can be applied to non-oily painting surfaces: canvas, paper, wood? For canvases, a sizing coat is necessary before application of the gesso primer. It can be used as it is or diluted in water (80 to 90% gesso with 20 to 10% water according to the consistency desired). It can be applied as it is or tinted by pre-mixing it with Sennelier acrylic colours. It penetrates the surface and allows good paint adhesion. Sennelier gesso is suitable for many techniques: acrylic, oil, watercolour, tempera, egg tempera, casein, gouache? For acrylic, one layer is sufficient, for oil, two layers are recommended. Dries rapidly.
