Primary Gesso is used under painting colors to reinforce coverage and adhesiveness and takes only 10 to 20 minutes to dry.?It serves to preserve the original shine and color of the over-paint while enhancing its preservability. It is necessary when painting on fabric, canvas, wood, clay, cement, or concrete. It should be applied after diluting with water to 20 to 30% using a large brush or a roller, and painted three times making sure to completely dry between layers to maximize its performance. When diluting, uneven mixture must be avoided as this may later cause cracks. It is suitable as an under-paint for not only Acrylics but also for Oil colors.
