Daler-Rowney Masking Fluid is the ideal solution for protecting areas of watercolour artworks from washes of water-based colour. It can be used to create striking white highlights or areas for overpainting at a later stage.This fluid forms a fast drying water-resistant film on water colour paper or board, easily removed when dry by rubbing with an eraser, soft tissue or cotton bud. An old brush, pen or cotton bud should be used to apply the Masking Fluid as it is extremely difficult to remove from brushes when dry.75mlEasily removed when dryProtects areas of your work from washes of water based colourPerfect for watercolour workDaler-Rowney Art Masking Fluid 75ml
