1. Gel Medium adds body to thinner paint for impasto techniques as well as extending color volume and adding transparency.
2. Gels tend to dry slower than thinner paint films, allowing for more workable time. Gel medium can contain acrylic resins, which tend to improve adhesion and durability.
3. When creating a sculptural ground, be sure to use adequate pressure to force the gel into the raw canvas, to ensure proper bonding. Apply paint over the gel after the gel is dry.
