Can this Gesso be used to provide a ground with "tooth" for soft pastels, turning say watercolour paper into suitable pastel paper?
Thank you for your enquiry.
The Winsor & Newton Clear Gesso is made from unpigmented clear resin which dries completely clear.
It has a balanced absorbency and excellent tooth this gesso creates the perfect surface upon which to paint. It is more suited for Oil and acrylic painting.
When using soft pastels, it is important to have a surface which allows the pastel to grip. You can try and create a slightly rougher surface for the pastel to grip by using sandpaper over the gesso.
You can use soft pastels on watercolour paper without a primer as it will act like a traditional pastel paper.
Or try a watercolour ground which offers a more absorbent ground and textured.
Some pastel surfaces offer a more grippy texture in order to reduce the dust and the need to use a fixative. If you are looking for a surface like this then there are grounds which are specifically for use with pastels and offer as more textured support.
