Gesso is used in artwork as a preparation for any number of substrates such as wood panels, canvas and sculpture as a base for paint and other materials that are applied over it.
- In the past we used Rabbits skin glue or gypsum. Now we use calcium carbonate in a latex base. Works on a rigid or flexible surface.
- Used to prime a surface, a canvas, hardboard or a wood surface.
- Protection against Support Induced Discoloration. Support Induced Discoloration is an issue that can occur when you apply a gel or a medium on a surface such as masonite for example. The impurities in the masonite are wicked to the top of the surface where the gel then becomes discolored.
- Prepares for reception of paint. Helps to seal and protect your surface.
- Colored gesso now available.
