Pébéo Ultimate Pouring Medium sets with catalyst

Pébéo Ultimate Pouring Medium is a water-based system of medium A and catalyst B for acrylic pouring with cellular and lace-like patterns. Mix the components separately with acrylic paint, then pass the catalyst mixture over the wet colours with a painting knife. The finish is satin; this is not ready-coloured pouring paint.

You receive one selected set. Every version includes an instruction booklet and access to Nancy Wood’s video masterclass. Choose Discovery if you also need paints and a knife, or a larger medium size if you already have those materials. Provide your own painting surface, mixing cups and stirrers.

Prepare two separate mixtures

For the background and each additional colour, use a separate cup to mix approximately 85–90% medium A with 10–15% acrylic paint. Stir for several minutes until smooth and free of lumps. Studio Acrylics is recommended. The proportion also depends on the fluidity of your paint; add a few drops of water only if needed.

In a small, separate cup, prepare a second mixture of approximately 50% catalyst B, 25% water and 25% acrylic paint. Only a little is needed. Mix until smooth and keep it separate from the background cups. Use the included booklet and video for the complete technique.

Pour, form patterns and allow to dry

Work on a rigid, suitably primed painting panel or supported canvas, with protection underneath. Pour the background and tilt the surface to distribute it. Pour the other colours on top or beside it. Pick up a little catalyst mixture on the knife and skim very lightly across the wet colours. Clean the knife after each pass and reload it.

Leave the work flat and undisturbed for at least two days to dry. Drying time and patterns depend on film thickness, paint and working conditions. Start with a small trial: record paint colours, proportions, water drops, colour order and knife movement. Compare edges, cells and sheen after drying. This is a suggested trial method, not a result from our own tests.

Handling and keeping a trial record
