Mont Marte Double Thick Pre-Primed Stretched Canvas – 91.4 × 121.8 cm (36″ × 48″)

Go big, stay bold. This 36″ × 48″ deep-edge canvas spans a cinematic 3 : 4 rectangle across a 38 mm kiln-dried pine frame. The heavyweight 380 gsm high-density cotton duck is triple-gessoed and ready to paint straight from the wrap, and an acid-free ground locks pigment vibrancy for decades. Because the span dwarfs 60 cm, Mont Marte adds a centre brace plus stretcher keys—so impasto peaks, collage layers, or resin rivers stay drum-tight and warp-free.

TL;DR – Gallery-depth 36″ × 48″ canvas, 380 gsm cloth, pre-primed, braced, and born for sweeping skies, hero portraits, and oversized fluid art.

FAQs

Do I need to gesso the Mont Marte Premium Double Thick Pre-Primed Canvas 91.4 × 121.8 cm?

No—triple gesso is factory-sealed.

Can the 36″ × 48″ canvas handle large resin pours?

Yes—380 gsm cloth and centre brace keep it rigid for generous layers.

Why choose a 3 : 4 aspect canvas?

It flatters portraits and landscapes and matches common print sizes.

How do I fix a warped canvas this size?

Lightly mist the back, lay face-down on a towel under light books until dry, then tap the keys deeper to re-tension.

Are staples visible on the sides?

No—staples are hidden on the back for a clean gallery wrap.
