I highly recommend using Liquitex High Gloss varnish for a gorgeous, gloss finish to your artwork.
Tip: Dilute a little of the varnish with a dash of water and use a sponge brush to spread evenly. It will help avoid brush strokes. Let each coat dry before applying the next coat. A little goes a long way!
The high gloss varnish from Liquitex is perfect to protect your art work from outside elements. Add a high glossy sheen to your work. Mix the varnish with other sheens and create a unique look to your art work.
