Acrilex Ultramarine Blue 543 fabric paint, 37ml, guarantees a classic blue depth with long-lasting cold fixation on cotton surfaces. Formulated with a water base for direct use, it evenly covers fabrics without a stiffened finish through clean brushstrokes or sponging techniques. It sets naturally at room temperature without the need for heat, and withstands frequent washing after 72 hours of drying. It is compatible with thinner for shading and suitable for tinting polymer clay. The ultramarine blue shade is indispensable for classic fine art illustrations, nautical motifs, and the personalization of fine textiles.
