Modern paint technology has facilitated the production of a true clear Gel Medium. The purpose of the Derivan Gel Medium is to act as a clear transparent gel gloss colour extender in the production of brilliant coloured glazes and as a transparent impasto for thick 3-dimensional brush and knife applications of Derivan Acrylics. Its prime requirement is to be thick and buttery whilst remaining fully transparent.
Available in 250ml size.
It acts as the main intermixing medium in acrylic painting when its rich buttery consistency is required for impasto work, 3-dimensional extrapolations, multi-layer work and heavy, smooth or textural glazes.
When dry, it maintains the structure, brushstrokes and textural effects of undiluted Derivan Acrylics colours. Its inherent firm and buttery consistency make it ideal for application by palette knife to achieve heavily textured grounds.
Reduced with water and Derivan Spreader Medium it adapts for thick but smooth flowing glazes.
Derivan Gel Medium, because of its viscous non-spreading consistency, enables the artist to apply thick and heavily defined brushstrokes.
It is well known that acrylic paints "surface" dry very rapidly but heavily imposed brushstrokes of paint take much longer to dry than thinly applied coats. The fact that the surface of the paint film dries rapidly causes moisture entrapment in the film underneath. This effect need not be detrimental to the painting as acrylic mediums are porous and allow for the gradual release of moisture during air drying. Nor does the artist experience any great problem of cracking or wrinkling because Matisse is a highly concentrated paint and once the available moisture has evaporated, the paint remains as a strong, solid, pliable and non-cracking film.
Avoid force-drying: The application of intense heat in order to prematurely dry paintings constructed with heavily imposed layers of colours is not recommended - the surface layers of paint can seal off, permanently trapping moisture underneath. Subsequently, the painting could crack and the canvas shrink or distort.
Derivan Gel Medium dries to a glossy finish.
Glass: Derivan Gel Medium can be applied directly to glass either by itself or with Derivan Acrylics.
Frosted glass finish: If a finish such as frosted glass is required, apply Derivan Gel Medium directly onto the glass.
