Pros
- Genuinely archival — acid-free core, professional ground
- Rigid surface doesn't flex or dent under the brush
- Fine tooth grips paint without showing canvas weave
- Takes oil, acrylic, encaustic, and mixed media
- Excellent value for an artist-grade archival panel
Cons
- Uncradled panels can cup at larger sizes in humidity swings
- Heavier than stretched canvas
- Smooth surface won't suit painters who want visible weave
Gessobord is what most painters mean when they say "panel." The construction is honest all the way through: an acid-free hardboard core, then multiple coats of true acrylic gesso, sanded between applications to produce a surface that's smooth without being slick.
The fine tooth is the quiet achievement. Too smooth and paint slides around with nothing to grip; too rough and the texture dominates the image. Gessobord sits in the middle, which is why it works across such different media.
Our Pick
The archival panel standard. An acid-free hardboard core with multiple coats of sanded acrylic gesso, giving a smooth, rigid, slightly toothy surface that takes oil, acrylic, and mixed media equally well.
Buy Gessobord for finished work in any medium. It's the default choice for painters who want rigidity and archival construction without preparing their own panels, and it suits detailed work that stretched canvas fights.
What we don't like
Uncradled 1/8-inch panels can cup slightly at larger sizes as humidity changes — above roughly 11 × 14 the cradled version is worth the extra cost. It's also heavier than canvas, which adds up when shipping a body of work.
