When using water-based paint media, apply this masking fluid to areas of your design or painting that you wish to retain as the original colour of the paper or background.
This masking fluid is watersoluble when wet but waterproof when dry. Once this is dry (about 15mins) apply your water-based colour over the top. Wait for the colour to dry thoroughly then remove the masking fluid by rubbing gently with your finger or an eraser. The original colour is revealed in those areas
Apply with any appropriate tool - pen, colour-shaper, ruling pen, cocktail stick, brush - whichever will make the mark you want.
The blue/grey of the fluid makes it easy to see on the paper but the colour will not transfer.
This particular masking fluid has a reputation for being able to create fine-detail marks; for not gumming up brushes** (can be washed in soapy water); and for not drying to a ball of rubber in the bottle.
**Would still recommend not using your best brushes!
