Lascaux Varnishes/Fixative
For the ideal finishing treatment of a work: acrylic varnishes increase resistance to the effects of weather, soiling and
mechanical stress and make cleaning easier. They have good adhesive properties, are non-yellowing, lightfast and
age-resistant. A final varnish can harmonize surface sheen in a painting.
Lascaux Acrylic Transparent
Varnish 1 gloss, 2 matt and
3 semi gloss
Composition
Pure acrylic resin dispersion
Properties
- water-thinnable
- dries to waterproof and clear film
- of superior transparency
- excellent adhesion, abrasion resistance and
hardness
- lightfast and age resistant
Applications
- Various applications on stable surfaces:
- protective varnish for acrylic paintings
- protective varnish for digital print
- painting medium for acrylic systems
- increases the hardness of Lascaux Artist and
Studio artists’ acrylic colours
- coating of wood, plywood and hardboard
- transparent wood varnish for interiors
Directions
Protective varnish for acrylic paintings: Provides excellent
protection against weathering, dirt and mechanical
damage. For use as a final varnish on painted objects,
dilute Lascaux Acrylic Transparent Varnish with about
25% of water and apply by spray gun or soft brush.
Leave to dry for 4-6 hours, then spray or brush on a
second coat.
The 1, 2 and 3 varieties can be mixed, allowing you to
adjust the degree of gloss as desired. A final coat
helps to bring out the intensity of the colours. Transparent
Varnish 3 increases the resistance without
altering the sheen of Lascaux acrylic colours.
Protective varnish for digital print: For best application
and to obtain an even coat the varnish is sprayed on. It
can also be rolled, whereby attention has to be paid to
avoid film irritations like air podcets.
Painting medium for acrylic systems: Add as required.
Increases the hardness of Lascaux Artist and Studio
artists’ acrylic colours: Mixed with Lascaux acrylic
paints, the varnish provides improved grip and hardness
and enhances the paints’ abrasion resistance.
Add 25-50% Lascaux Transparent Varnish to the paint.
Coating of wood, plywood and hardboard (chipboard,
etc.): Mix 1 part Lascaux Transparent Varnish with 1 to
3 part water. Apply one good coat to seal the surface.
When the varnish is dry, carefully sand off the raised
fibres.
Transparent wood varnish for interiors: Mix 1 part
Lascaux Transparent Varnish with 1 to 3 part water.
Apply one good coat to seal the surface. When the
varnish is dry, carefully sand off the raised fibres. Then
coat the surface with a mixture of 4 parts Lascaux
Transparent Varnish and 1 part water.
Special Notes
Before applying the varnish the paint layer should be
thoroughly dry. Depending on the thickness of the
layer, the temperature and humidity, this can take 1-2
days or longer if the layers is thicker.
The working temperature, given an average humidity of
40-60 %, should be above +8°C. When the humidity
(over approx. 75%) is higher, the varnish should not be
used below the temperature of 15°C, as problems in
the film building might occur otherwise. This applies for
both, the temperature during the application as well as
for the first hours of drying.
The film has to be thoroughly dry before exposing it to
the influence of weather or mechanical stress. Depending
on the thickness of the layers, the temperature and
the humidity this can be between 1-2 weeks, with
thicker layers even longer.
