Zellen paper glaze is an awesome product that can be used on paper crafts, watercolour, acrylic paints and more to create various effects. It is an acid-free, thick, glossy varnish that can be used to create 3D effects or simply to create a gloss layer over artworks or craft projects.
For those of you wondering – yes, you can use it over watercolour without your paint running or smudging! This is because it is not water-based like watercolour is. As you can see in the image below – the details and intricacies of the watercolour remain intact without any smudging. The varnish does make the watercolour appear darker though – which will happen with gouache too – so bear that in mind when working with it. You can use the darkening factor to your advantage – on coloured paper for example – to create images or patterns. See the heart example below.
Creating details with dots and lines or various shapes can add another dimension to your artwork, and accentuate details. Just be careful to work slowly when creating numerous dots on a page as you can get strands or ‘spiderwebs’ of varnish in-between. This is because the varnish is so thick and starts to become tacky quite quickly. Don’t worry too much if this happens though, as you can usually brush the strands away when dry.
You can use any sort of brush, but we found that synthetic acrylic brushes work well as they are soft, yet still springy and firm. Use thinners or acetone to clean your brush – turpentine won’t work here – and remember to clean your brush as soon as you are done working so it doesn’t get crusty! Drying time for the paper glaze is 24 hours but you will notice it becomes touch-dry in about an hour or two depending on the thickness. And if you’re wanting to thin down the glaze you can add a little bit of 95% ethanol/ alcohol until you reach the desired consistency.
