Priming Wood Panels With Acrylic Gesso
A wood panel is a better painting substrate because it is less susceptible to expansion and contraction than flexible supports, like canvas. The movement of these flexible supports can result in cracks and damage to the artwork created on them.
Ampersand offers several ready to use sealed and primed panels, but for artists that prefer to prime their own painting panels, enjoy working with a natural wood texture, or need strong support for encaustic, collage, or mounting, Ampersand also offers three unprimed wood panel options: Hardbord™, Unprimed Basswood, and Birch Wood Panel.
Commonly, artists ask us if unprimed wood panels need to be sealed. The answer is yes. If wood is not sized or sealed properly before applying gesso, yellowing can occur. This is because water (a solvent) can cause acids that occur naturally in wood to migrate to the surface. In fact, it is extremely important to properly seal all unprimed wood substrates to prevent support-induced discoloration that can cause your paint film to yellow over time.
