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 Matt Medium creates an even, flat finish, maintains brilliance of colour, and boosts 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 Matt 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. Galeria Matt Medium creates a smooth, velvety, matt finish, without affecting the original colour or strength of the pigment.

Good quality
This is my second purchase, excellent product and a good price.
Not used it a lot yet but seems fine so far. First time I've used matte liquid medium so have nothing to compare it to but I'm happy with. Got it at a very reasonable price.
Haven't tried is this a knock off too ?dont know yet
I use the product with stencils to create a relief which I then colour with watercolour pencils.
Dose what it says on the tin, :)
I use a lot of this Matt medium in my collages. It's a nice consistency, spreads easily & dries mat, so can be painted over etc. Good price from this company. Thank you.
