For airbrush we recommend Amsterdam Acrylic Ink. This ink has already been diluted and can be applied immediately, without thinning.
Amsterdam Inks have been tested with a 0.2 mm needle. In the colours white and metallic, the pigment parts are larger and we therefore recommend a 0.4 mm needle to prevent jamming.
Oil colours form a greasy layer and are therefore not suitable as a ground for acrylic colours.
Brushes made of firmer types of hair are the most commonly used for acrylic painting.
- Hog hair brushes can hold a lot of thick paint, but have a brush stroke that is too inaccurate for working in fine detail. What's more, with water hog hair brushes become a little less resilient.
- Synthetic (selected filament) brushes are not affected by water and are suitable for both thick and strongly diluted paint as well as fine details.
Acrylic colour brushes have a long handle so that sufficient distance can be maintained from the painting.
Mediums are used to change the properties of the paint, such as thickness, gloss, flow, drying time, transparency and durability.
A lot of painters only use water with acrylics, but this does not always produce the best results. Mediums can be used to achieve better and more durable results with less paint.
The addition of too much water can separate the pigment in the paint from the binder; the pigment is then unprotected on the painting and may run.
Acrylic Medium, Gel Medium, Heavy Gel Medium and Extra Heavy Gel Medium can be added to the paint unlimitlessly. Only the Amsterdam Acrylic thickening medium must be added in very small amounts.
