Acrylic fabric paint covers about 50 in² per ounce with brush application. A 12" × 12" design (1 ft²) needs about 3.2 oz for 2 coats. Spray paint covers less (~35 in²/oz) while fabric markers cover only ~15 in²/oz.
Heat-set acrylic fabric paint lasts 50+ washes when properly applied and cured. Mix any acrylic paint with textile medium (1:1 ratio) for equivalent results at lower cost. Always heat-set with an iron for 3–5 minutes.
Yes. Heat-setting makes the paint permanent and wash-resistant. Use a household iron on medium heat for 3–5 minutes over a protective cloth, or tumble dry on high for 30 minutes. Skip this step and paint washes out in 5–10 cycles.
Pour techniques use 30% more paint than brushing due to runoff. Stamp and stencil methods use 20–25% more because excess paint stays on the tool. Brush application is the most efficient with only 10% waste.
