Water colour medium Winsor&Newton Surface Preparation

Winsor&Newton Surface Preparation watercolour medium is a creamy foundation that transforms a wide range of materials—including canvas, plastic, wood, glass, and metal—into a subtly textured ground resembling watercolour paper. It prepares these materials for watercolour use, giving artists the freedom to paint on non-traditional supports.

Surface Preparation medium preserves colour intensity and achieves the ideal balance between absorbency and vibrancy, especially suited for artists seeking richer, truer tones. It forms a slightly textured, uniform finish with no patchiness, offering watercolour-paper-like absorbency. It allows better control of paint flow and saturation while preventing colours from appearing dull, and performs consistently on materials such as wood and canvas with no adhesion issues. For best results, apply two brushed coats, allowing each layer to dry fully before painting.
