Mont Marte Double Thick Pre-Primed Stretched Canvas – 50.8 × 76.2 cm (20″ × 30″)

Need a canvas roomy enough for sweeping brushwork but still studio-door friendly? This 20″ × 30″ deep-edge canvas rides on a 38 mm kiln-dried pine frame, hidden rust-proof back-staples and heavyweight 380 gsm cotton duck that’s triple-gessoed and ready to paint straight out of the wrapper. Acid-free sizing locks colour vibrancy and guards the fibres, so your statement pieces stay gallery-fresh for decades.

TL;DR – Mid-large gallery-depth canvas, 380 gsm cloth, pre-primed, perfect for expressive landscapes, portrait commissions and resin waves.

Key Features at a Glance

38 mm deep edge – sturdy profile resists warp and looks pro without a frame.

Back-stapled, zinc-coated staples – paint the sides; no rust freckles later.

Triple-gessoed, pre-primed surface – even tooth; acrylics & oils pop right away.

380 gsm tight-weave cotton duck – built for heavy-body acrylic, impasto oil & moderate resin pours.

Acid-free ground – stops yellowing, keeps fibres flexible for archival longevity.

Centre brace & wooden keys – extra support for texture-heavy techniques (sizes ≥ 60 cm get the brace boost).
