On wood panels, which preparation step is recommended?

• A. Gesso can be applied to wood to seal the surface and make it smoother.
• B. Gesso should not be used on wood
• C. Gesso is only for canvas
• D. Oil is best for priming wood

Answer: (A)

Priming wood panels with gesso is recommended because it seals the porous surface and creates a uniform ground for painting. Gesso fills the wood’s pores, reduces absorbency, and gives a consistent texture that helps paints adhere evenly and resist uneven drying or tannin bleed. It also protects the panel and provides a smoother, toothy surface for brushwork, which is helpful whether you’re using acrylics or oils. Gesso is not exclusive to canvas and is routinely used on wood as well. Using oil as a primer isn’t typical panel preparation because it can hinder adhesion of subsequent paint layers.
