Professional Gloss Varnish Spray

Seal your acrylic work with a transparent, gloss acrylic layer which is breathable, permanent and protects against UV damage.

Size: 400ml
Key Features
  • 100% acrylic polymer varnish adds a gloss sheen, protects and resists dirt retention
  • Increases brightness and color saturation and dries clear to a flexible, non-tacky, hard surface
  • Improves surface durability - ideal when shipping or exhibiting
  • Resists discoloration - yellowing and fogging - caused by humidity, heat and UV
  • Semi-opaque when wet, transparent when dry
How to Use
  • Before varnishing ensure paint surface is fully dry (72 hours-two weeks depending on thickness)
  • Ensure your space is well ventilated and dirt and dust-free. As this is permanent, do a patch test first
  • Place the artwork flat on a surface - always varnish horizontally
  • Use long, even strokes, covering the surface top to bottom while moving from one side to the other - don't go over bits you have missed, but leave to dry and then re-varnish area
  • Apply 1-2 thin coats, allowing at least three hours dry time between coats. If you require more than two layers, first use Gloss Varnish as a base layer and build to your desired thickness, then apply Gloss Varnish as your top coat

Even though they're tough and durable, acrylics love varnish. It's not just about protection; acrylic varnish helps unify your surface finish and increase color saturation, while slowing UV ageing and keeping out dust/dirt. And if you're moving pieces around or transporting them, varnish gives you an extra damage control. Whether you work inside or outdoors, our 11 varnishes can be used on all types of artwork. Choose from different surface sheens, application methods (spray or brush-on) and permanent or removable options. Our iconic Soluvar range allows you to periodically lift the varnish and reapply a fresh coat, while Gloss Spray increases color saturation and is ideal for heavily textured or vertical applications.

Can Liquitex Spray Varnish be used on top of traditional gouache to make it waterproof?

To waterproof gouache on canvas, you can use Liquitex Permanent Spray Varnish. However, subsequent paint layers may not adhere well to the varnished surface.

How do I look after my Spray Varnish and stop nozzle clog?

Prevent nozzle clogs by shaking aerosol cans before use and storing them above 15°C and spraying propellant to clear the nozzle. Hold the container upside and spray for a couple of seconds before and after use- this will send a spray of propellant only out of the nozzle and clear it.

How long should I wait between applying each layer of Liquitex Permanent Spray Varnish?

Ensure the artwork is fully dry before varnishing and allow at least 12 hours drying between coats of varnish.
