Chalky canvas

rudbeag

Hi I'm looking for some advice. I bought an acrylic triple-primed cotton canvas. The surface has a very chalky feel and some residue comes off if I wipe my hand over it. I've bought canvass from this company before and they weren't like this. Is it okay to paint on as is? Will the paint sink in? If it's not suitable, would a layer of acrylic paint (from a tube, not primer) or a layer of diluted oil paint make the surface okay to paint on?

Any help will be appreciated,
Best

I would not use that canvas. Any applied paint is unlikely to bond firmly to the surface. Delamination is a likely outcome.

Gesso is a simple mixture of titanium pigment, calcium carbonate (chalk) and glue. Probably the glue was missing, Insufficient or faulty.

Take it back for a replacement or refund.
