Mont Marte Double Thick Pre-Primed Stretched Canvas – 76.2 × 101.6 cm (30″ × 40″)

Go big, stay bold. This 30″ × 40″ deep-edge canvas sports a 38 mm kiln-dried pine frame with rust-proof back-staples and heavyweight 380 gsm high-density cotton duck. It’s triple-gessoed and ready to paint straight from the wrap, while an acid-free ground protects your pigments for decades. Because the span tops 60 cm, Mont Marte adds a centre brace and stretcher keys—so heavy-body acrylic peaks, collage layers, or resin waves stay drum-tight and warp-free.

TL;DR – Gallery-depth 30″ × 40″ canvas, 380 gsm cloth, pre-primed, braced, and built for cinematic landscapes, hero portraits and fluid-art showstoppers.
