Speedball Screen Filler 946ml
Designed to block out areas not intended to be screen printed. You can simply paint it onto the areas you do not wish to print and then leave the screen to dry, laid horizontally, somewhere with good air circulation. Once dry, it is ready to print with. Alternatively, first draw a positive image with Screen Drawing Fluid, then apply the Screen Filler all over the screen with a squeegee.
Leave to dry, laid horizontally, somewhere with good air circulation, then spray cold water on both sides of the screen mesh to wash out the positive image and allow to dry as before. Once dry the screen is ready to use.
