<p>Jackson's Wooden Circular Plywood Panels are made of smooth, sanded light plywood, reinforced on the reverse to prevent warping. Sturdy yet lightweight, they are perfect for plein air painting projects and work in the studio. The rigid, warp-resistant design provides a stable support for oils, acrylics, mixed media, encaustic, collage, and decorative projects.</p> <p>These panels are made from wood and are not primed or sealed. If the panel is to be used for painting, it is recommended that you seal the surface with a quality glue size or an acrylic-based primer. When you're applying acrylic primer, avoid thinning it with water. After sizing, we recommend priming with acrylic gesso and sanding the surface to produce a smooth yet slightly absorbent surface.</p><p>Jackson’s Circular Plywood Panels feature a robust 6mm or 31mm-thick plywood construction in a choice of diameters. The solid plywood surface ensures durability and a lasting, professional quality artists’ panel.</p> <p>This is a Jackson's 31mm deep Circular Plywood Panel with a 40cm diameter.</p> <p><strong>Please note,</strong> these panels are sanded smooth on the front only. The sides and rear may need sanding if so required.</p>
