How to use screen filler like a Pro

1

Before printing, completely air dry screen filler the same way you would dry your stencil. There should not be any moisture or wetness.

2

Use Ulano Extra Heavy Blockout No. 10 for easiest handling, whether for fixing pinholes or open areas with a single coating or with a coarse mesh.

3

For direct emulsion and CDF Direct-Film stencils: On the printing side of the screen, pour some Ulano Extra Heavy Blockout No. 10 onto the border area. Scrape it evenly into the mesh, using a piece of cardboard or plastic. Apply a second, “reinforcing,” coat to the squeegee side of the screen, if necessary.

4

For Indirect System stencils: For best register and a strong “knit,” between stencil and screen filler, apply the screen filler, as above, when the screen mesh is dry, but before the indirect film is completely dry. Apply the screen filler to the printing side of the screen, going over the edges of the backing sheet.

5

For touch-ups:Use as is or thin the screen filler with water and touch up with either end of an artist’s brush.

6

To remove Extra Heavy Blockout 10: Use water to dissolve screen filler after ink removal, but before stencil removal.
