Liquitex Soluvar Gloss Varnish (aerosol spray) (Item is spray can on right in above image.)Protects painting against harsh elements.
Spray on finished painting for a gloss varnish protection. (This is the gloss/shiny version. Not recommended for artwork that will have prints made of it.) Liquitex Soluvar Gloss Varnish is highly recommenmded because it is easily removed o touch up art as needed over the years. See below for instrctions on how to remove varnish with turpentine, (or go to professional restorer.)
Archival Removable Varnish For Acrylic and Oil Painings / Contains UV Light Stabilizers for protecting color
Resists discoloring (non-yellowing, non-fogging) due to humidity, heat and ultraviolet light.
Low viscosity, very fluid.
Apply as a final varnish over dry acrylic or dry oil paint.
Increases the depth and intensity of color.
Permanent, removable, final varnish for acrylic and oil paintings that protects painting surface and allows for removal of surface dirt, without damaging painting underneath. Once surface is clean, a new coat of Soluvar may be reapplied to surface.
Thin with mineral spirits or turpentine. Do not use Odorless Mineral Spirits.
Dries to a clear, non-tacky, water resistant, hard film that is resistant to retention of dirt and prevents dirt and pollutants from contacting paint surface.
Self-leveling. Will not hold brush strokes.
Flexible. Will not crack as surface expands and contracts during temperature and humidity changes.
For interior and exterior use.
Refer to Techniques on Airbrushing for more detailed information.
Most even application method.
Use for textured surfaces (thick impasto, thick textures), where brush application may result in foaming and fragile surfaces (watercolor, tempera, graphite, pastel, gouache), where brush application may disrupt drawing or painted surface.
Select air pressure (PSI) depending on air gun used and viscosity of varnish. Greater PSI permits thicker varnish to be sprayed, but may affect fragile surfaces.
2-3 light even coats are better than 1 thick coat.
Spray a continuous film by moving the spray gun in a smooth motion from one side of the painting to the other. First coat horizontal, second coat, third coat horizontal, etc.
During spray application maintain same distance across the surface of the artwork. Move your body as well as your arm to avoid "arching" motion and uneven application.
Good ventilation and a carbon dual filter mask are important.
Brush and Paint Pad Application
Use a wide, soft hair brush or paint pad (vacuum pad prior to use to remove lint). Size of area to be varnished will determine the size of the applicator. The smaller the surface area, the narrower the brush. Generally, a 1-4" flat brush is used.
Apply varnish in 1-3 thin coats, rather than 1 thick coat. A thick coat will take longer to dry, may dry cloudy, may drip or sag during application and has a greater chance of showing brush strokes when dry.
Horizontal surface application is best with less chance of varnish running. After varnishing, the surface should be shielded with a protective "tent". This will prevent any dust or airborne particles from settling into varnish as it dries.
Apply varnish in slightly overlapping pattern that covers entire artwork. Apply in horizontal and vertical brush strokes, so that entire area is evenly coated.
Do not rework areas you might miss, as the brush could pick up partially dried varnish and cause clouding. If areas are missed, wait until the varnish is dry and apply another coat.
Over Acrylic Paint
Allow acrylic paintings to dry for a minimum of 72 hours or longer if paint is very thick.
Apply 1-2 coats of Gloss Varnish as an isolation barrier. The barrier coat physically separates the acrylic painting from the Soluvar Varnish and seals the surface. This aids in a more even application of Soluvar Varnish and protects the painting if the Soluvar Varnish needs to be removed. Allow to dry for 3 days.
To insure proper adhesion, surface must be cleaned with lint free rag lightly dampened with mineral spirits.
Apply 1-2 thin layers of Soluvar Varnish. Let each layer dry 24 hours between coats.
Thinning increases penetration and can make it easier to apply varnish.
Over thinning may result in weak varnish film, poor adhesion, running and soaking into substrate.
Thin with up to 25% mineral spirits or turpentine. Do not use Odorless Mineral Spirits.
Remove varnish in clean, well-ventilated area.
Wear a dual filter respirator (NIOSH approved) and neoprene gloves. Dampen a small piece of lint free, soft, white cloth with mineral spirits (not "odorless") or turpentine - nothing stronger. Do not use ketones or paint removers.
Work horizontally. Apply mineral spirits generously and allow it to lay on surface for 15-30 minutes. Check periodically. Longer time may be necessary, depending upon age of artwork and strength of mineral spirits. If varnish is not dissolving or dissolving slowly, use a higher strength mineral spirits or turpentine (cover with plastic to slow down evaporation of mineral spirits). Stronger mineral spirits are not labeled as such, but have a stronger odor.
Rub cloth gently over a small area 1-2 square inches until varnish starts to dissolve.
Using a clean cloth and clean solvent, rub the area again to remove residue. Repeat this procedure for the entire area to be cleaned. If any paint color shows on the cloth, stop immediately and allow the surface to dry.
Allow painting to dry before reapplying a fresh coat of Soluvar Final Picture Varnish.
