For masking open areas:
• Pour on to the inside of screen & spread using either a coating trough, plastic spatula or a piece of stiff card
• Remove any surplus from the reverse side of the screen
• Allow to dry – warm air will speed up the process
• For coarse meshes re-apply as necessary.
For spotting out:
• Examine screens for pin-holes. Use a brush or non-sharp instrument to apply a spot of filler to any pin-holes.
