Winsor & Newton Permanent Masking Medium - 75mL

Permanent Masking Medium is a non-removable, water repellant liquid wax designed for masking specific areas of paper, making them resistant to water. This medium can also be mixed with watercolours and is ideal for isolating areas of fine detail. Sections which have been treated with Permanent Masking Medium must be allowed to dry before over painting. A hair dryer can be used to speed the drying. Once dry these areas remain protected and cannot be penetrated by further washes.

Excellent for detail. Apply directly to the paper or tint with small amounts of watercolour. Allow to dry completely before over painting.
