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.
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. .
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.
Impasto medium is a heavy-bodied paint, free of colour pigmentation (it isn't a gel).
It is most valuable for painting brush stroke and impasto techniques, particularly when heavy built-up areas of colour are required.
Impasto Medium dries to a low subdued sheen which is similar to the sheen on a dried paint film of acrylic colour.
It is equally water-resistant.
Impasto Medium is also suitable for use as a light modelling compound.
It can be applied by knife or brush in heavy blobs onto the original primed canvas and when dry, fully over-painted with Derivan colours.
Derivan Pouring Medium is a clear product that when applied to a surface or as a paint additive will automatically spread and create a smooth, glossy finish with minimal surface texture.
It is ideal for high gloss thick varnishing, pouring and marbling techniques.
Apply with a brush, palette knife or Refillables containers.
Can be tinted with Derivan Acrylics or Derivan Inks
Printing Gel is used in silk screen printing with Derivan acrylics.
Both Derivan Student and Artist can be mixed with Derivan Printing Gel to keep the colours from drying and clogging the screen mesh.
Using this medium, many prints can be made at one time without having to clean the mesh between every print.
Screen printing can be done on paper, board or fabric.
For fabric printing use Derivan Fabric Fixative in conjunction with the acrylic colours.
Printing Gel is also used to reduce colour strength when transparent colours are required for printing.
Mix the Printing Gel into the colour until desired transparency is reached.
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.
Derivan Viscosity Thickener
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.
Derivan WB Cracking Medium 250ml
Put medium onto surface, when dry paint over colour and it will crack.
Crackle can be painted over colours so top coat will crack to reveal base colour. Must be Matisse Flow or Structure and done within 12 hours.
Impasto Medium is a semi- opaque modeling paste applied witha brush or palette knife to produce three-dimensional structured affects.
Mix the medium with Global Colours Acrylics as an economical extender and to maintain a firm buttery consistency.
No visible colour change will occur when mixed in equal quantities with the colour.
The medium can also be used direct onto any prepared surface and then painted over when dry.
This medium will not crack.
Flow may be adjusted by adding water or other Global Mediums.
Not suitable for use as a glue or for transparent effects, for which we recommend Global Gel Medium.
Global Regular Gel Medium
Gel Medium will increase the transparency and brilliance of Global Colour Acrylics without altering the smooth impasto consistency.
An excellent binder for powdered pigments, sand, sawdust etc, as well as being an ideal glue for attaching heavy objects to a hard surface.
Global Gel Medium dries to a smooth satin finish but can be mixed with water or any other Global Medium for a wide range of effects.
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.
