Winsor & Newton Galeria Acrylic Mediums

Push the performance of Galeria Acrylics further with Galeria Acrylic Mediums!

Winsor & Newton’s Galeria Acrylic Mediums are designed to work with their Galeria line, allowing you to explore the full range of acrylic property possibilities, from thinned fluid media effects with Flow Improver to heavy, carvable paste that can be tinted and built up. Slow drying time with Retarder, thin and extend acrylic color, and even Varnish Galeria works for final shine and protection.

Galeria Extender - A highly economical medium, Galeria Extender increases volume of paint and maintains opacity. Color will dry to a matte finish. A great product for those on a limited budget.

Galeria Flow Improver - Additive that loosens the surface tension of water within the acrylic paint, increasing the flow and allowing the application of areas of flat color evenly without changing the color strength. Increased flow is ideal for masking application, flowing gestural watercolor-like techniques, and “staining" applications. Should be used only in the amount needed to achieve the desired effect.

Galeria Fluid Retarder - and additive for extending the drying and working time of acrylic colors. Small amounts (a few drops) will allow for extended blending and manipulation. Fluid Retarder does not contain sufficient acrylic resin to act as an additional “binder" and should be used only in the amount needed to achieve the desired effect.

Galeria Gloss Medium - high clarity and even flow, Gloss Medium boosts the brilliance and transparency of the color as well as improving adhesion and durability. Ideal for glazing or applying thick, highly transparent layers of brilliant color for depth and “stained-glass" effect.

Galeria Gloss Varnish - A unique, removable gloss varnish of the protection of finished acrylic works. Can be mixed with Galeria Matte Varnish to vary the final varnish.

Galeria Heavy Carvable Modeling Paste - Tough and fully carvable, it remains flexible on a variety of surfaces and is suitable for multiple layers. Formulated to have the least effect on color shift from wet to dry. May be overpainted. Acrylic color may be added directly into paste during application (note it will become lighter and ‘chalky’ and the resulting paste will have reduced body).

Galeria Iridescent Medium - Developed to provide pearlescent effects when added to color. Most effective when used with transparent colors over dark under layers.

Galeria Matte Medium - Creates a flat, even finish. Maintains brilliance of color while boosting transparency, adhesion and durability.

Galeria Matte Varnish - a uniquely removable matte varnish which may be mixed with Galeria Gloss Varnish to vary the final finish.

Galeria Satin Varnish - A uniquely removable satin varnish for the protection of finished acrylic paintings.

Galeria Modeling Paste - a lighter weight, flexible modeling paste for use on canvas (to minimize sagging). Finely textured with a soft sculptural consistency. Suitable for building multiple layers. May be overpainted, color may be added directly to paste (will become lighter and more ‘chalky’, and give paste a reduced body). Matte finish.

Galeria White Gesso Primer - made from high quality acrylic resin with a good level of pigment strength, can be used straight from the container and provides excellent tooth for adhesion. To reduce absorbency and boost film integrity of the film a minimum of two coats is required if working with oils.
