​

A non-removable, water repellant liquid wax designed for masking specific areas of paper, making them resistant to water. When dry, the medium will repel superimposed washes. Excellent for detail. Apply directly to the paper or tint with small amounts of water colour. Allow to dry completely before overpainting.

​

All watercolour washes mixed with Permanent Masking Medium remain open and workable while the wash is still wet. Once dry, the area becomes isolated and cannot be fully penetrated by further washes. A hairdryer can be used to speed the drying. Brushes should be washed in warm water and soap before using other colours.

​

・Permanent Masking Medium can be added to colour

・Brushes are easier to clean

・Art Masking Fluid is recommended for crisp whites and larger areas of masking, and is faster drying, while Permanent Masking Medium is recommended for fine detail and expressive effects within the painting.
