Once touch dry your paint may “sink” ie dull matt
patches appear. To freshen up the picture and to give temporary
protection you may use Retouching Varnish. This is a dilute
varnish which, if used sparingly in thin layers, does not affect
the long term drying process.
Talens Retouching varnish – is non-yellowing and dries
in a few hours. The spray format is useful for keeping layers
thin. Roberson retouching varnish is available in 60ml and 250ml
bottles. |

Once your picture is properly dry a final varnish can be used
to give a uniform degree of gloss and protection to the paint
layer. We recommend a modern non-yellowing varnish.
Rembrandt Picture Varnish is available in gloss and matt which,
according to Talens, can be mixed together to adjust the degree
of sheen. It is available in liquid or sprays.
Roberson Picture Varnish is available in 60ml and 250ml bottles.
(Matt varnishes are created by the addition waxy matting agents.
Using too thick a layer directly on to your paint can cause
a milky effect in areas which are more porous. To avoid this
I suggest applying a thin layer of gloss varnish beforehand
in order to give a uniform absorbency). |
