Aqua Fix developed by the reknowned company Schmincke for their quality watercolour paints dries watercolours to be waterproof.
It avoids dissolving of colour when painted in several layers and allows more possibilities for transparent painting.
It is best practice to clean your brush and palette thoroughly with water and soap immediately after using Aqua Fix.
Note do not mix medium and colour in the pan.
