Q: Can a painting with the Michael Harding Non-Absorbent Acrylic Primer base be rolled for transportation?

A: Yes, a painting with a Michael Harding Non-Absorbent Acrylic Primer base can be rolled for transport, though not ideal. If rolling is necessary, ensure the primed and painted surface faces outward. Use a large-diameter tube to reduce pressure on the surface, and interleave with protective materials like silicone release paper or glassine to prevent abrasion. Roll the painting loosely and unroll as soon as possible at the destination to minimize deformation or stress on the primer layer.

Q: Can I use Michael Harding Non-Absorbent Acrylic Primer on fine canvas?

A: Yes, the Michael Harding Non-Absorbent Acrylic Primer can be applied to fine canvas, but the weave should be assessed first. Hold the canvas up to a light source-if light is visible through the warp and weft, the weave is too fine and may not provide optimal adhesion for the primer. For best results, use a medium- to heavy-weight canvas with a tighter weave, which will support the primer application more effectively. This helps prevent seepage and ensures a stable, even surface for subsequent painting layers.
