What is Masking Fluid?

Masking fluid is an art medium used to preserve white areas and highlights in watercolour paintings. Composed of a water-resistant latex solution, masking fluid can be easily applied to paper to block out areas where the artist wants to maintain the paper's natural whiteness. Once dry, masking fluid forms a protective barrier that resists water and paint, allowing artists to add intricate details and colours without worrying about accidentally overpainting these preserved sections. Masking fluid is typically applied with brushes, dip pens, or other applicators. It is removed once the painting is complete, revealing crisp, clean highlights.

Why Do Artists Use Masking Fluid?

Artists use masking fluid to retain the white areas of their paper, creating striking highlights and intricate details within their work. By applying masking fluid to specific areas before painting, artists can ensure that these parts remain untouched by paint, allowing for precise control over light and shadow in their work. This technique is invaluable for maintaining the luminosity of the paper and for creating contrast within a painting. Additionally, masking fluid helps prevent accidental smudging or overpainting, enabling artists to work confidently and experiment with complex layering techniques. Whether used for detailed work, landscapes, or abstract compositions, masking fluid is a fundamental tool for achieving professional results. ‘Masking fluid can be a real game changer for your watercolour painting, as it allows you to keep very fine highlights, even when placed among the most fluid and bold brush marks. It can be applied with a variety of tools, from a brush to a toothpick, and dries on the paper to provide a waterproof cover over the parts of your painting that you wish to keep unpainted. You can then paint your work in as carefree a manner as you wish, knowing that when the painting is dry you will be able to remove the masking fluid to reveal crisp, bright white details.’ - Lisa Takahashi, Jackson's Art Supplies Expert

How Long Have Artists Been Using Masking Fluid?

Masking fluid has been a staple in the toolkit of watercolour artists for decades. Developed to address the challenges of preserving white spaces and creating clean highlights, masking fluid quickly became indispensable for artists seeking greater control and precision in their work. While traditional watercolour techniques date back centuries, the innovation of masking fluid allowed for new levels of detail and complexity in paintings. Artists have utilised masking fluid to achieve intricate patterns, delicate highlights, and sophisticated layering effects, pushing the boundaries of watercolour art.
