Planning the painting: This is very important!
First read through all the notes and watch the video clips -
Pebeo masking fluid's consistency is thinner than most masking fluids which allows a variety of tools to be used including hinged ruling pens, gillott pens, tooth brushes and watercolour brushes. When using a watercolour brush apply generously, if the fluid is applied too thinly it is very often difficult to remove.
If this is the first time you have used Masking fluid, a little practice before you apply this to your farm drawing will be worth the time taken, after you have finished your trial let it dry and apply a few colour washes over it, then let the colour dry totally before removing the Pebeo.
Never apply the fluid to damp paper and never try to remove it from damp paper.
Remove it by rubbing your fingers over it. Try it out on your - trial pad!
