Pebeo Gesso Primer White with a matte finish, is a highly opaque coating for preparing surfaces like cardboard, wood, and canvas for painting. It's suitable for clean, grease-free surfaces and enhances paint adhesion with its thick consistency. Once dried, it becomes permanent and provides a resilient film. For a white surface, apply a single coat of White Studio Acrylics Gesso, known for its exceptional coverage due to high titanium white concentration.
