- Gesso is used to prepare canvas for painting. It is very similar to white acrylic paint, only thinner. It dries hard, making the surface more stiff. 1
- Gesso consists primarily of calcium carbonate and a synthetic compound known as acrylic polymer latex. 3 This is derived from petroleum and formed through a chemical emulsion process. 5
- Petroleum required to make this product contributes to fossil fuel extraction, damaging wildlife habitats and contaminating waterways.
- May cause skin irritation. Avoid ingestion and contact with eyes, and wash hands thoroughly.
Safe Use and Exposure
- Avoid skin contact, use gloves. Closed containers can explode violently when heated, due to excessive pressure build-up.4
- Acrylic polymers should not go down the drain as they cause difficulties for waste-water treatment processes. Dispose of the material as solid waste, or donate usable gesso to the givetake. 7
- Soy-based gesso is made from organic material. The properties of soy-based gesso are the same as acrylic gesso. 2
