This panel combines two of our most popular panels: our extra smooth Cotton Polyester canvas with the Rublev Lead Alkyd ground. The combination of the two creates a one of a kind painting surface unlike any other among the Artefex roster. This extra smooth canvas provides a consistent canvas pattern with the most minimal weave. The Rublev Lead Alkyd ground creates a less absorbent surface from the original acrylic ground of the 513 Artefex panel.
