Blockout Red 421 is an inexpensive, water-based solution used as a plastisol, UV and solvent-based ink barrier. This bright red blockout and touchup liquid has just the right viscosity to spread easily over every mesh count. Solvent-enhanced agents greatly reduce dry times, yet the formula is non-flammable. Blockout Red 421 is water-soluble therefore, it is not intended for use with water-based inks.

Bottom Line:  Hey, not every stencil will be defect-free.  Touch-up & go!
