Lascaux Water Resoluble works as a binder to make perfect watercolour paints (resoluble film) by mixing it with dry pigments or watersoluble colour pastes. Easy to use, they can be progressively thinned with water into flawless fluid washes. Paint films remain flexible in restoration work, this medium is used as a retouching medium, i.e. for paintings in layers. As a medium for Lascaux Aquacryl watercolour or Lascaux Gouache, if added to diluted water, Water Resoluble Medium will increase binder content and consistency. The sheen of the paint will change from a matt one to a silkier one and can also be used as the first layer on a support to reduce absorbency, thus facilitating subsequent colour washes.
To make small quantities of handmade paint, work dry pigments or paste directly into Water Resoluble Medium with a palette knife or bristle brush. Pigment is absorbed into the binder readily, forming a smooth paste.Wetting properties are improved by working the pigment into a stiff paste with Medium diluted in a proportion of 1 to 9 with water and then adding further amount of pure Medium as necessary. For larger quantities, the use of a whisk or mixer is advisable.Used as a binder, more Medium produces a water-colour, less Medium produces colours with a matt and opaque appearance similar to that of tempera or Gouache.Start with a 1:1 ratio and vary the ratio of Medium to pigment according to requirements (bearing in mind that light pigments need more binder than heavy ones).
