Daler Rowney System 3 Removable Screen Block is used over screen drawing fluid to create handmade stencils that can be used for multiple prints.
Once the screen drawing fluid has dried the entire surface should be blocked out with System 3 Removable Screen Block applied with a squeegee. When this is dry (aqpprox. 1 hour) the drawn image is washed out in cold water to leave an open-mesh positive image ready for printing. After printing, screens can be reclaimed by softening up the block with very hot water then vigorously washing out the System 3 Removable Screen Block with a suitable brush and a very strong soap solution such as undiluted washing-up liquid.
