Medium W

for water mixability

50043

Jelly like ("lean") medium for mixing oil colours with water instead of organic solvents such as turpentine or turpentine substitute. Increases gloss and transparency, reduces viscosity; harmonizes drying process; odourless. Mix 2 parts of oil colour and 1 part of medium W gel on a palette, than add water like you want; if necessary add more medium W gel. Painting tools can be cleaned with water. There is no change of the product quality based on the colour change of the raw material alkyd resin. Dosage: 50%.

Thinner: Water

 

Medium W is also available as a gel >

 

 

Handling

  • Shake well before use. 
  • Mix one part medium W with two parts oil paint on your palette; than add water as desired or more medium as needed.
  • Please clean tools like brushes or palettes as soon as possible with water or water and soap.
  • There is one typical property that medium W has in common with commercially available “ready-to-use” water-soluble oil paints and many types of acrylic colours. In a yet undried state, oil paints mixed with medium W and water undergo a shift in colour, appearing to be somewhat lighter in hue or even “milky”. (Effect depends on the colour shades of the oil paint involved and the amount of water added: The darker the oil paint and the more water is added, the lighter in hue the wet paint film will appear.)
  • Close immediately after use.
  • Store in a cool and dry place.
  • Individual pre-tests are required. 

 

General hints for painting in oil

  • Ideally, oil colours should be applied in thin layers. When working with oil colours in a pasty putty-knife or prima technique, we strongly recommend the addition of megilp 50034. It accelerates the through-drying of thicker oil paint layers, thus reducing the risk of cracking or other damage.
  • Also if a picture consists of several thin coats of paint, the bottom coats must be completely dry before other follow. For this reason, the traditional rule of oil painting "fat over lean" applies.
  • Dried oil colours and oil painting mediums with oils and/or alkyd resins show a tendency for yellowing specially in the dark.
  • For varnishing pictures being painted in oil please wait for minimum 8 to 12 month.

 

General hints for working with drying vegetable oils

  • Colours with a binder based on vegetable oils show a tendency for yellowing specially in the dark.
  • Materials such as cleaning rags, paper wipes and protective clothing, which are contaminated with the product may spontaneously self-ignite some hours later. To avoid the risk of fires, all contaminated materials should be placed in a close metal container soaked with water or washed out well with warm soapy water before disposal. Contaminated materials should be removed from the workplace at the end of each working day and be stored outside.
