This Artecho formula is non-toxic, quick-drying, and spreads smoothly, offering artists a lightweight, fade-resistant base that becomes water-resistant when fully cured. The 500ml bottle supplies enough primer for multiple projects, making it practical for studio use and larger works.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this black gesso change the way paint behaves?\u003c\/h3\u003e\n\u003cp\u003eUsing a black ground alters contrast, saturation, and colour perception—particularly useful for moody palettes, chiaroscuro effects, or when you want highlights to dominate. Artecho’s opaque pigment ensures consistent coverage so underlying materials won’t show through. The primer also creates a slightly toothy surface that improves mechanical adhesion for acrylics and some mixed media.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eOpaque, even black coverage for consistent underpainting\u003c\/li\u003e\n  \u003cli\u003eSubtle surface tooth improves paint grip and layering\u003c\/li\u003e\n  \u003cli\u003eModifies contrast so highlights pop and midtones shift perceptibly\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat surfaces can I use Artecho Black Gesso on, and how do I apply it?\u003c\/h3\u003e\n\u003cp\u003eApply the primer to canvas, paper, card, primed or raw wood, and other porous substrates.
