Winsor & Newton Permanent Masking Medium - 75ml

£7.00

Permanent Masking Medium is not to be confused with Masking Fluid. This medium is a non-removable and water repellent liquid wax (rather than a latex). It is designed for masking specific areas of paper and making them resistant to water. This medium is excellent for detail as it will repel superimposed washes. Permanent Masking Medium can also be tinted with watercolour but care must be taken to use separate water cups for brushes as the residue can affect the qualities of the standard watercolour paint. Allow this medium to dry fully before over-painting.
