“Grounds” are products used to prepare a surface for acrylic and/or oil painting. Good preparation will not only ensure good paint adhesion, but will prove more economical as less paint will be absorbed into the surface. Although acrylics can be applied directly to a surface without first applying a ground, the acrylic binder from the paint is absorbed too quickly into the surface being worked on. The result is a drab and disappointing painting, with a disagreeably fast drying speed. Acrylic grounds are recommended before painting.
Jo Sonja’s Gesso is a flexible acrylic ground with a high grit content which provides “tooth” on which to paint. It is not water absorbent and does not suck the moisture out of your paint when you start to work on it.
Available in black and white, Jo Sonja’s Gesso may be used instead of, or as well as, All Purpose Sealer. Usually
applied on very porous or uneven surfaces, the grit will have a slight levelling effect, which is beneficial for inferior surfaces or rough edges. Note: For deep grain or blemishes we recommend Jo Sonja’s Wood Filler for levelling.
