This exclusive speedball formula was created for safe and easy usage with speedball screen filler (block out solution). Position the screen in a horizontal, elevated position. Paint the drawing fluid over those area that you want to print.
After the drawing fluid is completely dry, apply the screen filler on the same side of the screen used for application of drawing fluid. Use a piece of stiff cardboard, plastic or squeegee to apply a thin, even coating over the entire screen. Use one pass only (multiple passes will prevent wash out of the drawing fluid areas).
After the screen filler is thoroughly dry, spray cold water on both sides of the screen. Concentrate the spray on the areas where the drawing fluid was applied. If some areas remain slightly blocked, scrub them lightly with a small, stiff brush on both sides of the screen. Allow the screen to dry in a horizontal position.
