A fluid additive specially formulated to enable paint to flow easily across a surface. It thins paint to the ideal consistency, creates cell effects and reduces cracking and crazing. It will not slow down the drying time, alter the colour, or lessen the adhesion of paint. Mix with DecoArt Pouring Packs to create stunning effects on canvas, wood, or other art surfaces. Ratios can be adjusted for a variety of effects. Water-based. Non-yellowing. Soap and water clean up. Mix slowly into paint to avoid creating bubbles. Once paint is dry, finish with DecoArt Clear Pouring Topcoat if desired. Tips for Pouring: Pouring Medium is a water-based product, designed to be mixed with water-based paints. Introducing water or other additives other than DecoArt's Pouring Medium into your paint may compromise the integrity of the paint's adhesion to the surface. Care should be utilized when using tape to mask edges or other areas of the surface. When removing the tape, wait until the paint is dry to touch. Use a craft knife to score along the edges of the tape. This will ensure the paint will not be pulled up with the tape.
