8oz jar of screen filler

Speedball Screen Filler can be used alone or with Speedball Drawing Fluid. The Screen Filler method of printing is called direct block-out or "Negative Method". This is where Screen Filler is used to block out those areas that you do not wish to print. This allows the ink to be forced through the screen wherever the Screen Filler has not been applied. This product is AP Non-Toxic and conforms to ASTM D-4236.

To clean up:
Use Speedball Speed Clean to remove screen filler or mix 1 cup of Arm & Hammer’s Washing Soda dissolved in one 1 gallon of water. Apply cleaner to both sides with paintbrush. Scrub with a nylon bristle brush. Apply again to both sides. Let stand in a horizontal position for three to five minutes. Scrub with a nylon bristle brush while spraying with a forceful stream of hot water.
