Use Colourless Art Masking Fluid on softer papers when there is any risk of staining from the pigmented Art Masking Fluid. Masking Fluid protects areas of your work when color is applied in broad washes.
- Unlike Permanent Masking Medium which is inter-mixable with water colours, Art Masking Fluid works by direct application to the paper.
- It can be applied to white paper or previously coloured areas.
- Shake bottle before use. Do not use on wet or damp paper.
- Use gelatine surface sized paper, this helps to prevent the fluid from adhering too strongly to the paper.
