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

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

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

Please note, this product should be shaken gently before use to disperse the matting agent. Over-shaking will cause bubbles.
