Cobra painting medium 091 - If you use painting medium the paint becomes smoother and fatter. This allows the paint to be smeared out easily and the brush stroke to become less distinct. Adding the medium does not affect the drying time. It does, however, increase the degree of sheen and the durability of the paint film. You can mix the medium with water and it can be applied in the layered painting technique perfectly well. Cobra painting medium is based on vegetable oil, synthetic resin and water.
Cobra glazing medium 092 - Cobra glazing medium makes the paint flow better. The added amount affects the degree of transparency. This technique – making coloured transparent paint layers without a brush stroke – is referred to a glazing. Cobra glazing medium is very fat and may only be applied in the last few layers of a painting. The medium increases the degree of sheen and the durability of the paint film, but does not affect the drying time of the paint. Cobra glazing medium is based on vegetable oil. It can also be thinned with water.
Cobra painting paste 087 - Cobra painting paste is a colourless medium that can be mixed with water mixable oil paint in any ratio. The paste is as thick as the paint and could therefore be described as a water mixable oil paint without any pigment.
Cobra painting paste has various uses:
Increasing the amount of paint:
Painting paste can be mixed with water mixable oil paint in any ratio. For example for impasto techniques (applying pure paint in thick strokes with a painting knife) using the more expensive colours you can increase the amount of paint without there being any colour difference. The more paste you add, the more transparent the paint becomes; depending on the type of pigment, however, this will not or hardly be visible in thicker layers.
Decreasing the colour intensity:
The colour intensity of the paint will decrease as more painting paste is added. This may be particularly important with the alla prima (wet-on-wet) technique when mixing colours with a highly divergent colour intensity with one another in the painting. By adding more painting paste to a stronger colour this will become less prominent.
