Gesso is a plaster-like primer applied to surfaces prior to painting. Originally developed for oil painting on canvas, gesso is now used for a wide variety of media on almost any surface. It was also called "glue gesso" or "Italian gesso".

When added to a raw surface like wood, the gesso added "tooth" - roughness - which helped the paint adhere, and prevented it from soaking in. This meant less paint was required, and the colors stayed truer.

This original gesso could be used as a base for oil painting, egg tempura, any water-based paint acrylics weren't invented yet , or painted onto any three dimensional surface in preparation for applying gold leaf. Because traditional gesso dried very hard, it was only suitable for rigid surfaces, and would crack and chip on flexible substrates When canvas needed to be primed, linseed oil could be added to the gesso, giving it the flexibility required for the softer surface that might, in future, be rolled.

This mixture was sometimes called "half-chalk ground". Wood panels are one of the most common painting surfaces, though metal, plastic, and cardboard are suitable as well. The most common type of gesso used today is acrylic gesso. It was invented in the s by the brand Liquitex. In lieu of the animal glue of old, acrylic gesso uses a polymer latex, mixed with chalk, white pigment usually titanium dioxide, which artists know as titanium white - it improves flexibility and other chemicals that ensure longevity.

Because it has no glue or gypsum, it is not technically gesso, but has retained the name. Essentially, modern gesso is just a painting primer. Though this new version of gesso is ideal for acrylic paint, and suitable for most oil painting as well, it is not as absorbent like the traditional primer, and does not work for egg tempura. In recent years, some oil artists have begun to question whether acrylic gesso is really a good choice for oil painting - it's thought a mismatch in the flexibility of the media can cause problems over time.

None the less, companies that offer acrylic gesso, like Liquitex and Golden, maintain that it is suitable for both. One professional artist suggests using it most of the time for oil painting, but using an oil-based gesso for any major or important work.

Using recycled soy products, this primer is "low-emitting", and uses a binder that is a mix of oil and acrylic. The addition of oil is said to make this type of gesso more suitable to canvas - it's more flexible - and may be better suited to use with oil paints. Gesso Canvas without gesso Canvas with gesso.

Secure lid and shake, this step will reduce airborne talcum, do not stir as it will send off particles into the air.

Remove masking tape slowly after 5 hours of drying time- varies depending on your humid or dry climate. Caution, paper will warp. Surface is toothy, sanding is optional if smoothness is desired.
