Each beautiful surface is ready for traditional priming, gessoing, or mounting canvas, linen, or cotton papers (easily accomplished using Soho Gloss Gel, a permanent, acid-free adhesive). These artist-grade gesso panels are primed with acid-free, professional quality acrylic polymer gesso. The MDF smooth hardboard panel is first sealed, and then coated up to three times with the gesso primer. Kiln dried New Zealand Pine cradles provide an incredibly strong, true support that will not warp due to its’ excellent dimensional stability. All styles of panels have been thoroughly tested for long term warp resistance, making them perfect as an archival painting or mounting surface.
