Watercolour mediums expand creative possibilities by altering drying time, flow, gloss, and texture. Winsor & Newton also offers masking fluids to preserve white areas on paper.
Mediums
Add a small amount to paint to achieve desired effects.
Gum Arabic
Main binder in watercolour; controls flow, slows drying, and increases gloss and transparency. Enhances blending and reduces staining. Dilute with water as needed.
Ox Gall Liquid
Wetting agent that smooths washes and improves flow by reducing surface tension. Suitable for hard-sized paper. Use 3–4 drops per cup of water.
Blending Medium
Extends drying time for smoother blends and allows working colours into each other without affecting colour properties. Dilute with medium or water. Effective even in hot climates.
Granulation Medium
Low-viscosity formula that enhances granulation, creating mottled textures in colours that are normally smooth or intensifying granulating pigments. Dilute generously for best results.
Texture Medium
Contains particles that add fine texture and depth. Can be applied directly or mixed with paint to build textured layers. Shake well before use.
Aquapasto
Translucent gel that thickens watercolour or gouache to create impasto effects with added plasticity.
Effects
Effect auxiliaries enhance watercolour paintings with pearlescence or aid in lifting paint.
Iridescent Medium
Adds a metallic, pearlescent shine. Works best mixed with transparent colours or applied over dry washes, especially on dark backgrounds. Shake well before use.
Lifting Preparation
Applied to paper before painting, it prevents paint from sinking in permanently. Once dry, allows easy removal of watercolour with a wet brush or cloth for corrections or special effects.
Masking fluids
Used to protect areas of paper from paint, preserving the original colour.
Art Masking Fluid
Lightly tinted liquid that temporarily masks paper to prevent paint adhesion. Ideal for fine details. Avoid use on damp or soft-sized paper. Remove promptly after use. Clean brushes with water immediately.
Colourless Art Masking Fluid
Clear, non-staining version of masking fluid for temporary masking. Same usage and care instructions as tinted masking fluid.
Permanent Masking Medium
Non-removable, water-repellent liquid that masks paper areas permanently, repelling washes to preserve colour. Can be applied directly or tinted with watercolour. Allow to dry fully before painting over.
