Atelier Slow Medium
For extending drying time. It also allows thinly applied paint to remain workable. Even paint which feels dry to the touch can be reactivated with water for reblending techniques.
Atelier Clear Painting Medium
Prevent runs in diluted paint applied vertically on an easel. It is used with the paint to dilute the viscosity and blend colours. This medium allows paint to spread over a surface for more blendable gradations of colour and fast glazing techniques.
If washproof fabric paint is required, Derivan Fabric Fixative mixed with Derivan colours will become permanent on clothes after heat fixing. Mix equal parts of Fabric Fixative and Derivan colours, then paint and let dry before you heat set with an iron to make the garment wash-fast. Some synthetic fabrics are non-absorbent and thus not suitable for paint application.
Test your fabric beforehand. Also avoid applying the paint too thickly as this may cause the paint to crack. Heat Fixing Prints It is necessary to heat fix the image.
To render it washproof. Heat fixing can take many forms.
Retarder as the name suggests, retards or slows the drying time of the paint. There are two ways to use this medium.
The first is to use up to 3% Retarder to colour; this will result in a slightly more fluid colour that will stay wet for much longer.
The second method is to put the Retarder in a hand pumped spray bottle (atomiser) and spray it onto the painting you want to keep wet. (The spray bottle should create a mist not a hard squirt).
Additions of drying retarder to mixing water may be used in water colouring, water wash effects, stain painting and hard edge techniques where it assists in pigment wetting, rapid colour diffusion and penetration. .
Spreader Medium: is used to spread large volumes of transparent colour over selected areas while maintaining a controlled paint viscosity. Acrylic colour can be added in small or large increments to the Spreader Medium.
Spreader Medium is a transparent flowing paste. It dries fairly "flat" and when dry can hardly be discerned on a painted or unpainted area, i.e. it leaves almost no stain. Its main application is for glazing where it imparts fine flow and controlled spreadability and lubrication to the paint.
This is an additive that is meant to be stirred into the colour to give a thick buttery consistency. Originally it was formulated to give the perfect paint thickness for screen-printing. However, it is now widely used to thicken colours to achieve an impasto effect in painting.
Add 2 teaspoons of thickener per 250ml of paint. Use sparingly as this a very effective medium (not compatible with fluorescent colours). Paint that has been thickened with Viscosity Thickener should be used within 48 hours or so.
GOLDEN Gel Mediums offer artists many ways to build texture. They range in consistency from pourable to moldable with varying degrees of sheen and transparency. They can be used to create glazes, extend paints and change finishes. Some gels incorporate pumice, glass or acrylic granules that impart unique reflective, rough or absorbent surface qualities.
Gels can be thought of as colorless paint, as they are composed of 100% acrylic polymers similar to acrylic paint. They can also act as adhesives in collage and mixed media that dry to form continuous films with excellent flexibility with chemical, water and UV resistance.
Mediums and Additives
GOLDEN Mediums offer artists infinite control of changing acrylic colors. Use Mediums to control transparency, viscosity and surface sheen. Mediums can be thought of as colorless paints, as they are composed of similar polymers as are the acrylic paints. They are the "glue" or binder that dry to form continuous, durable films. They are made of 100% acrylic polymers, which have proven to have excellent flexibility and chemical, water and ultraviolet radiation resistance.

GOLDEN Pastes are tools that artists can use to achieve a variety of effects and expressions. Pastes used in conjunction with acrylic colors broaden working properties and expand creative possibilities.
Pastes differ from most gels in that they are opaque and may contain Marble Dust, Diatomaceous Earth, fibers, clays or other fillers resulting in a white or clay-tone finish with a variety of textures and properties. Pastes can also be used to create textured foundations for painting.
Extra Heavy/Molding Paste – A blend of Extra Heavy Gel Gloss and Molding Paste. Dries to a satin, semi-opaque finish. Excellent for increasing viscosity and building surfaces
