Description
Langridge Impasto Medium is an incredibly thick clear-gel medium. Add to oil colours to for extra body without altering the colour.
Constituents: Refined Safflower Oil, Â Fumed Silica, Cobalt Drier, Calcium Driers
Product Application:
Langridge Impasto Medium should be added to oil colours in quantities no more than 25%. Mixed with oil colours, it may be applied with a brush or palette knife in thicker films than any other Langridge medium. Initially small additions will stiffen the handling of existing oil colours. As more medium is added, the oil colour will be suspended and extended forming a thick paste. When worked using a brush or palette knife the medium becomes slightly looser allowing for easy incorporation with colours. The Safflower oil content in Impasto Medium is slow drying allowing for a wet-in-wet technique with very controlled manipulation of paint including soft blending.
Langridge Impasto Medium has a high oil content and, as such, is a fat medium. Due to its physical nature Langridge recommends not over painting Impasto medium with any other medium.
Dries to a satin finish.
Thinning: For best results thin with Distilled Gum Turpentine. However, Artists White Spirit or Langridge Low Toxic Solvent may be substituted. The use of the latter solvents will tend to reduce the fatness of stroke and the oil film will dry with less richness due to the partial destruction of the paint film.
Appearance:Â Langridge Impasto Medium is a clear paste with a characteristic safflower oil odour. Very fresh medium may exhibit a slight bluish-grey cast. The colour of the medium will not effect the oil colours with which it is mixed.
Clean Up: Clean brushes with any artists solvent (e.g. Gum Turpentine, Low Toxic Solvent, etc). For further washing apply a small quantity of Marseille or other pure olive oil soap and massage the bristles of the brush to release any remaining colour. Wash thoroughly in warm water. Leave to fully dry before using for oil colours.
Drying Times 48-72 hours to touch dry. Any airflow over the surface will evaporate the solvent more rapidly which will reduce drying times.Full film drying 3-6 months in less than 3mm thickness.
