Here’s the secret to painting detailed areas or leaving white areas in your artwork without messing it up! This liquid masking fluid is removable and meant for temporary coverage. Test it on the paper you’re using to be sure you get the result you want before doing using it on your artwork. When you’ve applied it and let it dry, you can paint over the film with watercolour.
Surfaces such as paper boards, photo paper or film won’t absorb the colour. When the areas around the applied masking fluid are dry, you can remove the masking fluid with an India rubber or your finger. Just make sure you rinse your brushes in water immediately after using masking fluid.
