Colourless Schmincke Masking Fluid will not stain the paper and should be used on watercolour papers that softer, such as a 100% cotton paper. This Schmincke Masking Fluid Pen has a fine tip nozzle so that a precise application of masking fluid can be achieved. It is ideal for creating the fine details, lines, scripts, etc.
Designed for use with Watercolour Paints, Schmincke Masking Fluid is a removable masking fluid that should be used to mask off the areas that you want to remain white.
Once the masking fluid is dry you can paint over it with your watercolour paints without the worry of the paint going onto an area that you want to keep colourless.
Do not leave the masking fluid on the paper for longer than 2 days. Once the painting is finished and dry, simply rub off the masking fluid with your finger or an eraser. It is easy to remove.
Shake well before use.
