Winsor & Newton Watercolor Mediums

Art Masking Fluid — This liquid is applied to make areas resistant to watercolor. Has a slight yellow tint. Not recommended for use on damp or soft sized papers, or if yellow staining of paper is a risk (Instead use Colorless Art Masking Fluid). Made from latex. Do not dilute.

Blending Medium — This medium slows the drying rate, allowing extra time for blending watercolors. As a result, it is particularly useful in hot climates. Dilute color with medium alone for maximum blending time.

Colorless Art Masking Fluid — A removable, colorless liquid, use it for masking areas of work that need protection when color is applied in broad washes. It is specifically designed for soft sized papers to avoid staining. Made from rubber and latex staining. Wash brushes immediately after use. 75 ml glass bottle.

Granulation Medium — A medium that is known for giving a mottled or granular appearance to colors that usually give a smooth wash. For maximum effect, dilute color with medium alone.

Iridescent Medium — Mix this medium with watercolors or apply it over a dry wash to give iridescent or glitter effects. It is particularly effective when mixed with transparent colors.

Lifting Preparation — Apply the medium directly to paper and allow it to dry before painting. The preparation then allows dry washes, including staining colors, to be more easily lifted from paper with a wet brush. Ideal for making corrections.

Ox Gall Liquid — Ox Gall is a wetting agent used with watercolors. It increases the flow of washes on the painting surface. It can also be used for marbling.

Permanent Masking Medium — A non-removable, transparent liquid mask, this medium is excellent for detail. It can be applied directly onto the paper, or mixed first with watercolors. Ensure that the fluid is thoroughly dry before overpainting. Wash brushes in warm, soapy water before using other colors.

Texture Medium — Producing a textured finish for watercolors, this medium can be applied directly onto the paper, or mixed with watercolors first.
