Acrylic Paint Area Calculator

Acrylic paint quantity per square meter

How far acrylic paint goes comes down to opacity, viscosity and how absorbent the surface is. A single coat by brush or roller usually runs 0.1–0.3 L/m². Two coats, which is what most people recommend for full coverage on canvas or wall, land around 0.2–0.6 L/m². The math is V = A(m²) × coats × rate. That rate climbs on raw cotton or rough stucco and drops on primed canvas or polished drywall.

Acrylic is a water-based polymer, normally polyvinyl acetate (PVA) or a pure acrylic polymer dispersion. It dries as the water evaporates, taking 30–60 min at 23 °C / 55 % RH, and reaches full cure in about two weeks. Artist-grade brands like Acrilex Acrilex Galeria, Liquitex and Golden carry a 60–70 % pigment load, while architectural brands such as Suvinil, Coral and Sherwin-Williams aim for roughly 12 m²/L per coat on a wall. ANVISA classifies decorative and cosmetic acrylic finishes under low-VOC regulations.

Applications

Handy for pricing canvas commissions, stocking up the studio or budgeting an interior repaint. A 1×1.5 m canvas in two coats eats up about 600 mL; a 12 m² bedroom wall in two coats runs near 2 L. Mural artists, set designers at Globo Studios and DIY renovators heading out to Leroy Merlin or Telhanorte all lean on the same formula.

FAQ

Do I always need two coats? Going dark over light, or laying a saturated tone over white, yes. The first coat is rarely opaque enough. Light tones over a matching primer can sometimes close in one.

Can I dilute acrylic with water to stretch it? Up to about 25 % water and adhesion holds. Past that, switch to acrylic medium (matte, gloss or flow-aid) so the polymer binder survives.

Why does my acrylic dry darker than expected? Wet acrylic holds a milky white emulsion that clears as the water leaves, so the dry colour always ends up a step deeper. Test on a scrap before you commit to a large area.
