Question about Edding Clear lacquer spray

The clear varnish is basically suitable for fixing and protecting paint applications on many materials, including paper and cardboard, which indicates a possible suitability for watercolour and gouache paints. It is a quick-drying, silk-matt acrylic clear varnish that is water-resistant, lightfast and smudge-proof, thus protecting the colours from yellowing and fading.

However, the available product information does not explicitly mention that it is specifically recommended for watercolour or gouache paints. As these colours are sensitive and may be altered or discoloured by spray paints, caution is advised. The varnish is suitable for decorative items and similar applications, which indicates a certain compatibility with sensitive surfaces.

In summary: The clear varnish can be used to fix watercolour and gouache paints if a protective, water-resistant coating is required, but a small test area should be used to check that the colours are not affected before use. There is no explicit manufacturer's recommendation for watercolour or gouache paints.
