More Information

What is a Medium?

Any liquid which changes the consistency of the paint it is mixed with may be classed as a medium. Liquitex mediums are designed specifically for use with acrylic paints, and produce effects ranging from thin glaze to thick impasto, 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.

Acrylic Mediums: Exploring The Possibilities gives further information on the Liquitex range of acrylic mediums, and how they can be used.

Why choose Liquitex Slow-Dri Fluid Additive?

Providing a fluid consistency when added to acrylic colour, medium or gel, Liquitex Slow-Dri Fluid Additive extends working time by up to 50%, and increases flexibility. Aiding colour blending and detailed brushwork, Slow-Dri Fluid Additive also prevents paint skins forming on the palette.

Ideal for using with Soft Body Artist Colour, Liquitex Slow-Dri Fluid Retarder is suitable for mixing with all paint and mediums within the Liquitex Range. However, it should be noted that the thickness of Heavy Body Artist Colour and Heavy Body Gel Mediums will be reduced to a more fluid consistency.  

Fully intermixable, all Liquitex Mediums are water resistant and ph neutral when dry, non-yellowing and permanent.

How do I use Liquitex Slow-Dri Fluid Additive?

Liquitex Slow-Dri Fluid Additive does not contain sufficient acrylic resin to act as a binder, and should only be used in the amount needed to achieve the desired effect. Adding more than 25% Fluid Additive to colour will prevent the paint from drying.

Who are Liquitex?

Founded in 1933 by Henry Levison, Permanent Pigments, an oil colour producing company from Cincinnati, Ohio developed the first water-based artist acrylic paints. Their new formulation was launched in 1955, under the new company name Liquitex, an abbreviation of “Liquid texture”, which Levison believed better captured the product’s essence.

Today, Liquitex offers a vast array of intermixable vibrant acrylic paints and mediums, enabling artists to continually explore new and innovative ways of working with Acrylic Colour.
