Derivan Screen Block Out is the second part of a two part silk screen paint system.
After painting on the Derivan Screen Drawing Fluid and letting it dry, apply the Derivan Screen Block Out to the whole silk screen.
Allow the Block Out to dry then you can wash out the Drawing Fluid with water to reveal your design. You are now ready to print. The screen will last for many prints. When you finish your print run you can remove the block out with soap and warm water leaving the screen clean and ready for your next design.
