Jo Sonja : Artists' Mediums : 60ml : Gloss Polyurethane Varnish

Jo Sonja Gloss Polyurethane Varnish is a clear, non-yellowing polyurethane varnish designed to protect painted and decorative surfaces with a durable gloss finish. Fast drying and suitable for both indoor and outdoor work, it is used as a protective topcoat to help preserve the finished surface over time.

It is applied full strength in thin layers, with a Jo Sonja Clear Glaze Medium barrier coat recommended beforehand, depending on climate and humidity. For greater durability, multiple coats can be built up, with 4 to 5 coats recommended for alcohol-resistant or outdoor use, and the varnish should be allowed to cure for at least two weeks before use.
