What the AI looks for in Paint Primers & Sealers
- Ground compatibility
- Acrylic gesso accepts both acrylic and oil; an oil ground accepts only oil. Acrylic will not adhere over oil.
- Size before oil on raw fabric
- Size raw linen or cotton with an acrylic size, PVA or acrylic gesso before an oil ground. Oil in direct contact with fabric fibers rots them.
- Coats and sanding
- Apply two to three thin coats, alternating direction, and sand lightly for a smooth surface. Thin layers bond better and give an even tooth.
- Panel sealing
- Seal wood or hardboard panels before gesso to block support-induced discoloration. Tannins and resins can migrate and yellow the ground.
Brands that matter
- Golden: Gesso, GAC sizes and Absorbent Ground.
- Liquitex: Professional and Basics gesso.
- Gamblin: Oil Painting Ground and PVA Size.
- Winsor & Newton: Acrylic gesso primers.
What to avoid
- Rabbit-skin glue on flexible canvas, which cracks with humidity
- House primer on fine art supports
- One thick gesso coat instead of several thin ones
Questions
Is pre-primed store canvas good enough?
Usually yes, but cheap canvases have thin gesso; an extra coat improves tooth and absorbency.
