What artists like about the Black Box Canvas, 40mm Deep Edge

“I love dry media as well and it works like a charm for charcoal. It is very forgiving and beautiful enough without framing.”

Jeanette Du Plessis

“Perfect, as advertised. Sturdy, no warping, drum tight.”

Daniel le Roux

“They are tight and smooth and you can add texture quite easily without sagging of the canvas.”

Linda McDonald

Questions artists ask

Do I need to prime or gesso this canvas before painting?

No. The canvas arrives pre-coated with our proprietary black gesso, ready to paint straight from the box - for oils, acrylics, mixed media and fluid art. You can apply additional gesso if your technique calls for it, but it isn't required. TIP: For oils, mixing mineral turps and linseed oil into your underpainting works particularly well on this surface.

Will the canvas stay tight over time?

Yes. The fabric is 100% Virgin Polyester, which doesn't react to humidity the way cotton or linen does, so tension stays where you set it. The strainer is engineered - dimensionally stable, no pine warping. Independent research at the Victoria & Albert Museum found polyester showed no measurable loss of strength under museum conditions equivalent to 80 years of display.

Can I use oils, acrylics and heavy texture on it?

Yes. The 300gsm Polyester surface holds oil evenly without sinking, takes acrylics without absorption issues, and handles palette knife and impasto work without denting. For oils, mixing mineral turps and linseed oil into your underpainting works particularly well on this surface.

How many canvases come in a pack, and what sizes are available?

Black Box Canvas is sold in packs of 2. Sizes range from small study formats up to 1000mm × 1000mm (40″ × 40″) and A0 (841mm × 1189mm). Every canvas in the pack is matched in tension and finish.
