Professional Masking Fluid, 4 oz (118 mL)

Control your composition with precision using Professional Masking Fluid. This removable liquid latex barrier protects designated areas of your surface from paint, ink, or other media, allowing for clean edges and crisp highlights when removed. Suitable for use on paper, board, and primed canvas, it applies easily with a brush or tool and dries quickly to a flexible film. Once paint is fully dry, the masking fluid peels away cleanly without damaging the surface. Perfect for artists working in acrylic, watercolor, ink, or mixed media, it enables detailed layering, resist techniques, and precise control in complex compositions.
