Video: Winsor & Newton Galeria Mediums

Winsor & Newton Galeria is a collection of mediums designed to enhance the creations of artists working with acrylic paint, such as 
Winsor & Newton’s Galeria Acrylic Colour range. Galeria Gloss Medium provides an even flow, high clarity, and boosts colour brilliance, transparency, adhesion and durability.

What is a Medium?

Any liquid which changes the consistency of the paint it is mixed with may be classed as a medium. Winsor & Newton Galeria Acrylic Mediums are designed specifically for use with acrylic paints, and range from thin glaze to thick impasto mediums, with a variety of choices in between.

Why use a Medium?

By changing the properties of paint, a medium extends the possibilities of how an artist works with the colour, and affords a plethora of exciting techniques and effects.

Winsor & Newton Mediums Finder provides an easy, interactive method of choosing the correct medium, for the artist to achieve the desired effect.

Why choose Winsor & Newton Galeria Gloss Medium?

 All Winsor & Newton Galeria Mediums are fully intermixable, and can be layered or mixed on the palette, allowing the artist to fully explore both the textural and visual properties of Acrylic Colour. Giving a clear, brilliant finish, Galeria Gloss Medium is ideal for applying thick, highly transparent layers for strong depth of colour, glazing or creating a “stained-glass” effect.
